Title: Simultaneously twisting and interlacing a continuous multifilament yarn
IPC: D02G1/16
Filed: 1969-10-02
Abstract: A multi-filament yarn is processed by subjecting the yarn to the action of a jet of gaseous medium and twisting the yarn so that the point of action of the jet is disposed at or near the point, disposed above a wind-on bobbin, from which, in the direction towards a traveller, a yarn balloon forms in operation. As shown, multi-filament yarn 1 passes through a guide duct 9 to the traveller of a twisting ring 12 to be wound on a bobbin 14 co-axial with duct 9. The thread balloon formed between the traveller and duct 9 thereby rotates around the latter. The yarn in duct 9 is subjected to the action of a jet of compressed air directed thereon by a nozzle 10, the axis of which is disposed at right angles to the axis of duct 9 and in alignment with the axis of a blind resonance bore 11. Various forms of air treatment devices are described.

One of the pair of cams, referred to as a two color cam, is arranged to open and close the two color grippers for two color printing and the other of the pair of cams is arranged to open and close the perfector grippers and the two color grippers for perfector printing. The pair of cams, i.e., the two color cam and perfector cam, are secured to each other and movable axially relative to the transfer cylinder. The perfector grippers and two color grippers have a cam follower associated therewith that is actuated by either the two color cam or the perfector cam. The two color and perfector cams are connected through a lever mechanism to an actuator device that is arranged to move the pair of cams axially relative to the transfer cylinder. The tumbler is also connected to the actuator device located on an exterior portion of the press so that the actuator device simultaneously moves the pair of gripper actuating cams and the tumbler cam to adjust the transfer cylinder for either the two color or perfector printing.

Title: Feeding device for advancing undelimbed tree trunks
IPC: B27B25/02
Filed: 1975-03-12
Abstract: A feeding device for use with tree processing machines such as delimbing, barking and slashing machines wherein feed rolls are provided on each side of a feed path for the tree trunk.

Title: Winding machine friction clutch - incorporates idling arrangement permitting driven part slow movement and prevents faster inertia running
IPC: F16D21/08
Filed: 1977-03-28
Abstract: The device is for coupling a driven part to a drive, particularly for a drawing or winding machine and has a friction clutch which permits the torsion of the driven part against the drive against friction force. To prevent the further rotation of the driven part (1, 20) by reason of its inertia when the drive (3) stops, a free run or idling arrangement (1, 9, 5) is fitted between drive and driven parts. This allows the slow movement of the driven part (1, 20) relative to the drive (3, 5) but prevents the driven part (1, 20) running through its own inertia as opposed to the drive (3, 5). The driven part (20A) of the friction clutch (12, 14, 20A) is arranged between two counterposed surfaces (12, 14) of the drive (3).

Title: Traverse bottom structure of bag
IPC: B65D30/24
Filed: 1977-09-30
Abstract: The ends of the flattened tube that is to form the plastic bag are first turned outwards, forming flanges at the sides connected by turned-under triangular pieces at the ends.
