Abstract: 820,831. Knitting-machines. STIBBE & CO. Ltd., G. Jan. 10, 1957 [Jan. 16, 1956], No. 1399/56. Class 74 (2). Needle selection is made at each feeder of a multifeeder circular machine, for example, a superposed cylinder machine, by a selector unit, the bits 26 of which act on selecting jacks 25 which raise first intermediate jacks 20 so that their butts engage a raising cam 22 to cause them to raise second intermediate jacks 16 such that their butts are engaged by a further raising cam 17. The cam 17 raises the second intermediate jacks and consequently the needles through their abutment with the lower end of the sliders such that the needles are raised to a height whereat the yarn is fed beneath their latches. Each jack in turn is immediately returned to its lowered position after having been raised by its appropriate selector or cam 26, 22 or 17 by a lowering cam 29, 24 or 19 respectively. In addition to needle selection for yarn feeding mentioned above, needle selection may also be made prior to the main feeder for links-links patterning and operates in a similar manner such that the selected needles are transferred into the upper cylinder. A lower selector jack cam 27 is also provided in advance of each selector unit to bring the selector jacks to the correct height in which they engage the lower end of the first intermediate jacks. By providing butts 25b of varying length and appropriately positioning the cams 27 by operating them as bolt cams, further patterning selection can be achieved. The first intermediate jacks 20 are chamfered at their lower rear edges so that the butts 20b of those which are not selected are pressed inwardly causing the jacks to pivot by engaging the face of the raising cam 22, the leading edge of which is appropriately bevelled to accommodate the butts. A recessed portion 23a is provided in the upper guide cam 23 to permit the upper portion of the jacks 20 to pivot outwardly when the butts 20b are depressed. Specifications 761,994 and 820,832 are referred to.

Abstract: 764,453. Wrapping-machines. PACKAGING MACHINERY CO. Jan. 25, 1955 [April 16, 1954], No. 2183/55. Class 94(1). In a machine for wrapping thin flat articles, such as rashers of bacon, the articles A are supported on cardboard pallets P and fed in succession into the machine by pushers 2 on an endless conveyer 1, each article and pallet engaging the depending end of a wrapper web Wand being pushed into a clamping device on an oscillatable transfer member 4, whereby the web is folded about their leading edges. The member 4 is then swung upwardly into alignment with an inclined sealing channel 5, whereby the web is folded over the upper side and trailing edge of the article by a roller 6 and a flexible member 7, and the wrapper is severed from the web by a knife 8 to leave an extending portion b sufficient to overlap the portion a previously applied to the undersurface of the pallet. The partially-formed package is then removed from the clamping device by one of a series of pairs of pushers 31 on intermittentlyoperated endless chains 32 and the member 4 is swung downwardly to receive the next article and pallet. During the first step of movement of the chains 32, the portion b is folded upwardly by the floor of the channel 5 to overlap the portion a, thus forming the wrapper into a tube having portions extending beyond the ends of the article. At a first sealing station, the overlap is heat-sealed by a plate 38, which is swung upwardly through an aperture in the floor of the channel, the ends of the extending portions of the tube are clamped by crimping dies 36, Fig. 11, co-operating with heated plates 56, and the extending portions are heatsealed between the clamped portions and the ends of the article by shoes 37 co-operating with heated members 79, thus drawing the wrapper tightly about the article. During the next step of movement, the sealed extensions are folded upwardly against the undersurface of the package and at a second sealing station spring- loaded pads 43, Fig. 7, engage the ends of the package to press the folded portion against heaters 80 which secure them in position. The dies 36, shoes 37 and pads 43 are mounted on rocking shafts 51 and the heaters on fixed shafts 50. Three pads 43 are provided for each end of the package and are individually spring- loaded so that they may adjust themselves to irregularities in its upper surface.
