Title: Improved process for the manufacture of bars, blocks, profiles and suchlike objects from polyamides and other artificial materials with a short melting zone
IPC: B29C45/00
Filed: 1951-02-13
Abstract: 702,672. Moulding bars &c. of polyamide resin. &c. NAAMLOOZE VENNOOTSCHAP ONDERZOEKINGO-INSTITUUT RESEARCH. Feb. 13, 1951 [March 21, 1950; Aug. 30, 1950; Aug. 30, 1950], No. 3513/51. Class 87 (2) In a process for moulding elongated articles of synthetic superpolymers having a fairly sharp melting-point, e.g. polyamides, in which a preheated elongated mould is filled with molten superpolymer and a constant stream of additional molten superpolymer is fed under pressure to the filled mould during progressive cooling of the mould from an end of the mould towards the feed opening, part of the constant stream of additional material is diverted through an overflow device under an adjustable constant pressure, the total amount of the additional stream of material exceeding the rate at which material is taken up by the cooling mould. The material may be obtained by melting material that has previously been polymerized and cooled, or may be freshly polymerized material. Figs. 1 to 3 show apparatus comprising column 1 in which polyamide is formed. The polyamide is fed by a gear pump 2 through a valve into a mould 3 supported on a head 5 and surrounded by a furnace 4. A gauge 7 indicates the feed pressure. When the mould has been filled the furnace is removed (Fig. 2) and the end of the mould remote from the filling end is cooled by refrigerant from nozzle 10. A movable collar 11, e.g. of rubber, limits the cooling area. The collar is then gradually moved down the mould to the lower end, cooling being maintained during this movement and for some time afterwards. During the cooling, polyamide is forced into the mould and excess escapes past a valve 9a through a pipe 6. The valve is loaded by a spring the pressure of which can be adjusted by turning a screw 9. Fig. 4 illustrates a modification in which two moulds are used, one mould 3 which has previously been filled being cooled whilst the other mould 3<1> is being filled with the furnace 4 in position. The moulds are carried by a head 13 which can be rotated about a shaft 14 supported by a stationary head 5. When mould 3 has been cooled the supply of polyamide is stopped, the furnace is removed from mould 3<1> the head is turned through 180 degrees, the cooled mould 3 is unscrewed from head 5 and replaced by an empty mould, the furnace is reapplied, the supply of polyamide resumed and the process repeated. The polyamide enters the mould 3' through. passage 16 in stationary head 5, past valve 10 and through passage 18. A safety valve 20 indicates filling of the mould. Overflow from passage 16 proceeds to mould 3 via passage 17. More than two moulds 3, 3' may be used. Specification 656,725 is referred to.

Filed: 1947-02-11
Abstract: 621,255. Making pottery. MILLER POTTERY ENGINEERING CO. Feb. 11, 1947, No. 4003. Convention date, Feb. 6, 1946. [Class 87(i)] [Also in Group XIII] In a completely automatic step-by-step pottery-making machine, clay is fed into empty moulds 4 at A, pressed at B, shaped by a jigger C, dried by an infra-red dryer 2 and removed in a finished state at H, the empty moulds being returned by a conveyer 7. An empty mould is moved from the conveyer 7 to a position below the delivery pipe 9 of a pug-mill 8 to receive a charge of clay by a horizontally reciprocating fork. A second fork moves the mould to a transfer point L where it is received by the first of three ring checks which carry it successively to the press B, jigger C and a conveyer 51. It is pushed at D on to a conveyer 5 by a reciprocating plate 87. When sufficient moulds are assembled on the conveyer 5 to fill the width of the dryer conveyer 3 they are pushed by a plate 98 on to free rollers 75 and pass to the dryer conveyer. At F, they pass to rollers 122, of which the first two are driven, and are held by a stop 134 until a conveyer 6 is empty when the stop is lowered and they are drawn forward by a plate carried by a member 141. The conveyer 6 carries them to a transfer point G where a plate 162 pushes them on to a conveyer 7. The finished ware is removed from the moulds at H by a suction chuck and placed on a conveyer 218. If the ware is not removed owing to a fault &c. it is blown from the mould at J by a photo-electrically controlled air jet 224. The various conveyers are operated through a geneva drive, while the pusher members for shifting the moulds on to or off the conveyers are operated by pneumatic means controlled by cams and electric switches.
