       BACKGROUND 
       [0005]    1. Field of the Invention 
         [0006]    The invention relates to a single circular knitting machine, consisting of a central rotatable needle cylinder (Z), around which a sinker ring (PR), which rotates simultaneously, comprising sinkers (P) as well as stationary cam systems (S), which act on the needles ( 1 ), which are in each case assigned to the sinkers (P) and which can be moved vertically up and down. 
         [0007]    2. Background of the Invention 
         [0008]    The current state of knowledge is as follows. 
         [0009]    Single circular knitting machines are an important branch in the use of knitting machines. Over decades, a structural design has thereby established itself, which has since not been questioned anymore. The basic elements of all of the single circular knitting machines, which are available today, are the central needle cylinder comprising the needle slots for the latch needles arranged on the periphery, of an invention from the year 1852. In response to the knitting loop formation process, the needles are moved back and forth by means of control bases, which stick out of the periphery, via control curves in sector cam systems, which are arranged side by side on the periphery. When pushing the latch needles forward, the last knitting loop, which is located in the hook, must open the latch and must overcome the increasing interior latch surface, so that it reaches the needle shaft behind the latch. A sinker ring, which is connected to the cylinder and which comprises sinkers arranged in horizontal slots, the pitch of which is staggered relative to the needles, ensures that the knitted fabric is thereby not lifted off the upper cylinder edge (=cast-off edge). The movements of the sinkers must be accurately coordinated with those of the needles. This is carried out in a laborious manner by means of a sinker cam plate, which is stationary in the space above the sinker ring and to which the sector-like sinker cams are fastened on the bottom, said sinker cams move the sinkers, which are also provided with control bases, back and forth when they are rotated past in operative connection with the needles. An adjusting possibility, which is not easily accessible, is thereby necessary in the sinker cams. 
         [0010]    The enumeration makes it clear that many different courses of movement and functions take place simultaneously within a very small space of the knitting loop formation and that the stationary control systems, which are necessary for this, must be available. The demands on the accuracy have been increased extremely due to the needle pitches, which become finer and finer, so that fewer and fewer manufacturers can meet them, that is, a selection of only a few, who remain and who rule the market, is created. To alleviate the demands on accuracy, which meet in a confined space, the pitches of the cylinder and of the sinker ring, which meet directly, are particularly difficult.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0057]    The object of the invention characterized in claim  1  is to specify a single circular knitting machine, in the case of which the fixedly meeting pitches are replaced with a sinker grid system, which is flexible per se and which is oriented automatically in the needle gaps. The basic idea, which led to the invention, was to make the possible pitch accuracy in the needle cylinder to be the determining aspect for a more flexible allocation of the sinker in the functional area. The storage pitches of the sinkers could then be arranged further away on the sinker ring and the difficult taring of the tolerances of two pitches relative to one another, that is, the horizontal sinker slots would no longer be necessary. The connection of the sinker ring with the needle cylinder would be alleviated and would be possible without any problems. A more flexible sinker-grid formation is created in this manner from the storage to the needles in the cylinder. Different sinkers result, which are automatically oriented according to the needles when passing through in any system. Instead of the currently standard horizontal longitudinal movement, the sinkers are pivoted parallel to the needles. Advantageously, this has the result that, upon pushing the needles forward, the knitting loop is not only stopped, as has been the case until now, but is transported to the needle shaft in a more effective manner by means of a counter movement. In addition, the complicated sinker control by means of sinker cams, which are fixedly attached to a sinker cam plate above the rotating cylinder, becomes superfluous and the cam system takes over this task in a much more clearly arranged setup. The sinkers can furthermore be used as a template for inserting the thread into the needle hook, without having to additionally attach a thread guide. The current help from the take-up motion when casting off the old knitting loop by pushing it away by means of the sinker is replaced with a different measure. The described advantages have considerably simplifying effects on the overall design of the single circular knitting machine. 
         [0058]    A basic idea of the invention is thus to equip the sinker ring with a plate area, which in particular does not encompass any sinker slots and which is thus substantially flat, so that the sinkers are arranged thereon so as to be movable relative to one another, wherein the sinkers are in particular supported only on the outer periphery of the sinker ring. The ends of the sinkers on the needle side can carry out movements transversally to their longitudinal axis, so as to align in the needle gaps. These transverse movements are thus not limited by the side walls of the sinker slots, which are known from the state of the art. In particular, the sinkers form a so-called sinker grid system, which is to be understood in the instant application as the plurality of sinkers, which are arranged on the sinker ring and which are in a detachable contact with one another at least at one point. The contact thereby preferably exists only in a lateral contact of adjacent sinkers, as is described below in more detail. 
         [0059]    The invention can be used advantageously for all single circular knitting machine alternatives and considerably alleviates the demands on accuracy in the case of the ultra-fine needle pitches. 
         [0060]    Advantageous further developments of the invention are specified in the subclaims. 
         [0061]    The further development according to claim  2  relates to the geometric contexts in the determination of the pivot point of the sinkers (P) to the desired x-y movements of the sliding nose ( 47 ) in response to the knitting loop formation. 
         [0062]    The further development according to claim  3  relates to the front design of the sinkers (P) for the thread insertion by means of a template ( 46 ) and of the sliding nose ( 47 ). 
         [0063]    The further development according to claim  4  describes the possibility of the invention to hold the last knitting loop on the cast-off edge of the needle cylinder (Z) by means of the sliding nose ( 47 ) when pulling the new thread loop through. 
         [0064]    The further development according to claim  5  relates to the design of the pivot inlet ( 43 ) of the sinkers (P) and to the embodiment of the rocker ( 44 ). 
         [0065]    The further development according to claim  6  relates to the control of the sinkers (P) by means of the control curves ( 49 ), which are attached to a support rail ( 48 ) by means of the unit E. 
         [0066]    The further development according to claim  7  relates to the embodiment of the sinker ring (PR) with additional guide slits for the rocker ( 44 ), which are available in the area of the control curve ( 49 ) so as to be aligned laterally with the pivot point slits ( 41 ) and also serves to stabilize the sinkers. 
         [0067]    The further development according to claim  8  relates to the central connection of the needle cylinder (Z) to the sinker ring (PR). 
         [0068]    The further development according to claim  9  relates to the embodiment of the sinker P as a composite element of a sinker-grid formation. For this purpose, spacing bumps H are preferably attached above the cavity between needle cylinder (Z) and sinker ring (PR) at the sinkers (P) so as to be capable of being released or spacing springs or other space maintainers, for example in the shape of U-shaped slides, such that they encompass the entire needle pitch at this location. The sinkers thus contact one another on the spacing bumps, spacing springs or space maintainers, so that the thickness of the sinkers at this location accounts for the entire needle pitch. The sinkers thereby form a sinker grid, which refers to the sinkers located next to one another, which are thus in particular not connected to one another so as not to be capable of being detached. The sinkers are in particular located next to one another in a circle of contact. A single one of these sinkers as component of this sinker grid can also be identified as grid sinker. 
         [0069]    The further embodiment according to claim  11  relates to the stable embodiment of the sinkers (P) for the ultra-fine needle pitches. For this purpose, the sinker shaft preferably encompasses the full pitch distance above the cavity between needle cylinder (Z) and sinker ring (PR), and narrows laterally forwards for the engagement with the needle gaps, while lateral depressions, which form a guide latch ( 52 ) with the thickness of the pivot point slits ( 41 ), are preferably impressed in the back of the pivot inlet ( 43 ). It is thus possible for ultra-fine needle pitches to place the sinkers directly side by side, without providing for additional space maintainers, and to simply embody the area on the needle side to be narrower than the area, which is spaced apart from the needle. 
         [0070]    According to a preferred embodiment, provision is made for the pivot point projection to be embodied as an endless thread, which is arranged in a revolving groove, which is arranged in the outer periphery of the sinker ring. An advantageous support of the sinkers can be attained through this. 
         [0071]    Preferably, the endless thread is made of rubber or highly-elastic carbon or is embodied as a coil spring ring, which provides for a simple production. 
         [0072]    A sinker according to the invention for a single circular knitting machine in each case encompasses at the end, which is spaced apart from the needle, a rocker ( 44 ) comprising an upper and a lower control bump ( 45 ) as well as a pivot inlet ( 43 ), wherein the thickness of the sinker (P) encompasses the full pitch distance at least at a distance to the end on the needle side. Through this, the sinkers are located laterally side by side at least at a distance when arranged in the machine and they are stabilized against one another, which makes it possible to use a flat plate area on the sinker ring instead of the otherwise common sinker rings comprising sinker slots, whereby the sinkers can be oriented according to the needle distances, because the transverse movements thereof are not limited by sinker slots. 
         [0073]    According to a preferred embodiment of the invention, the sinker encompasses a spacing bump or a spacing spring or a space maintainer, which is preferably embodied as a U-shaped slide, at a distance to the end on the needle side. Through this, it is made possible to determine the desired pitch space in a simple manner. 
         [0074]    According to an advantageous embodiment, the sinker shaft narrows laterally forwards, starting at the distance to the end on the needle side, in which it encompasses the full pitch distance, for the engagement with the needle gaps, while lateral depressions, which form a guide latch ( 52 ) with the thickness of the pivot point slits ( 41 ), are preferably impressed in the back of the pivot inlet ( 43 ). Such sinkers can be produced in a simple manner. 
         [0075]    Exemplary embodiments of the invention will be defined by means of  FIG. 1  to  FIG. 24 . Unless otherwise specified, all of them are embodied in an enlarged scale of approx. 5:1. The direction of rotation of the cylinder (Z) and of the sinker ring (PR) is thereby clockwise. 
       DETAILED DESCRIPTION OF THE FIGURES 
       [0076]    Referring now to the figures, The first housing, according to  FIGS. 1 and 3  (e.g. a motor housing for holding an electric motor) is connected to a second housing, according to  FIGS. 1 ,  2  and  3  designed as a modular transmission housing  2 , according to the connection structure of the invention. 
         [0077]    The motor housing  1  is designed with a cylindrical shape and on the output side has a bearing plate with a cylindrical flange  7 , in which the output shaft  9  of the electric motor is mounted. 
         [0078]    The transmission housing  2  holds a planetary gear and comprises a motor flange  2   a  with which the motor housing  1  is connected. In addition, the transmission housing has two gear stages  2   b  and  2   c , each of which comprises an annular ring with sun gear, planetary gears and planetary carrier (not shown in the figures). The closure on the output side of the transmission housing  2  forms an output flange  2   d  with an output shaft  10 . 
         [0079]    For connecting the motor housing  1  with the transmission housing  2 , the motor flange  2   a  is equipped with a hollow cylindrical recess  3 , which is formed of a circular collar  4  on the drive side of the transmission housing  2 . The inner diameter of the hollow cylindrical recess  3  formed by this collar  4  corresponds to the outer diameter of the motor housing  1  in the area of its bearing plate with the cylindrical flange  7 . This hollow cylindrical recess  3  also has a central pocket hole  3   a , the inner diameter of which corresponds to the outer diameter of the cylindrical flange  7  of the motor housing  1 . 
         [0080]    As the cross section representation according to  FIG. 3  shows, the motor housing  1  is inserted with its cylindrical flange into the recess  3 , whereby the flange  7  is held by the pocket hole  3   a  for centering the transmission housing  1 . The face side  11  surface of the motor housing  1  lies flush on the recess base  12  of the recess  3 . 
         [0081]    For axial and radial fixing and securing of the transmission housing  2  on the motor housing  1 , the transmission flange  2   a  has two radially-running threaded screws  5  as tensioning elements in the area of the collar  4 , which are each screwed into a diametrically opposed threaded hole  13 , until they each engage in an engagement groove  6  on the lateral surface of the motor housing  1  and because of this the transmission housing  2  is tensioned against the motor housing  1 . 
         [0082]    The motor flange  2   a  is equipped with a drive shaft  8  in a ball bearing, which is in active connection as a four-cornered shaft with the output shaft  9  of the motor housing  1 , whereby this output shaft  9  has a hollow shaft profile with recessed square. 
         [0083]    Naturally, the invention is not restricted to this active connection that is explained, rather any other suitable active connection can be provided between the output shaft  9  of the motor housing  1  and the drive shaft of the transmission housing  2 , e.g. a usual motor-side output shaft with motor pinion pressed on. 
         [0084]    According to  FIG. 3 , the drive shaft  8  of the motor flange  2   a  is connected to a sun gear  14  of the gear stage  2   b  mounted on the motor flange  2   a  by means of a threaded connection  15 . 
         [0085]    Finally, a tensioning element different from the threaded pins  5  shown in the exemplary embodiment can also be used; e.g. the use of a snap ring is also suitable.
