Title: Sepg. socks knitted as a continuous strand - by atomising heat sensitive connecting thread detected photo electrically
IPC: D04B15/88
Filed: 1975-08-20
Abstract: Socks are knitted in a continuous strand on a circular machine. The socks moving down from the knitting zone to a zone of the machine beneath are joined together by threads which collapse when exposed to heat. This joining zone of the socks, is pulverised by a medium raised to a temp. at which the joining threads disintegrate, during the descending motion as the socks leave the knitting zone. A photoelectrical device is used to detect the position of the connecting zone between the toe of one sock and the welt of the next and to initiate the pulverising action. At the commencement of the passage of the strand through the station where sepn. takes place, a downwards tension is applied to the sock by jets of compressed air which widens the joint so that reflectors provided to assist the working can direct the rays to the light sensitive element. System prevents any damage to the sock by a sepg. mechanism, and saves the extra operations necessary to remove the remnants of the joining thread.
