Title: Improvements relating to machines for winding yarn
IPC: B65H54/28
Filed: 1942-10-17
Abstract: 559,927. Winding yarn. MACKIE & SONS, Ltd., J., and MACKIE, J. P. Oct. 17, 1942, No. 14573. [Class 120 (ii)] In a machine for winding yarn into cross-wound packages or cheeses and in which the yarn is traversed by a roller having two separate oppositely directed helical grooves in its surface each extending from near the centre line towards one end of the roller, the yarn is caused to return from one end of the roller towards the centre by the pull of a moving guide eye or member which also gives a small lateral displacement to the yarn first towards one side and then towards the other side of the centre line, the displacement being sufficient to cause the yarn to enter the groove leading to the opposite end of the roller. As shown the yarn from the supply bobbins o passes through a fixed guide b and under a pin d to the surface of the moving guide member e which, takes the form of a roller having a single deep helical groove e<SP>1</SP> in its surface, and from the roller e to the traverse roller f having two oppositely directed helical grooves o, p each terminating at the end of the roller in a short reversely directed end q and near the centre of the roller being formed with a splayed end v for picking up the yarn easily. The moving guide roller e is geared to the traverse roller so that it imparts the maximum throw to the yarn towards one side just when the yarn is required to enter the groove in the roller f for traversing towards that side or end of the roller. A reciprocating guide eye on an arm or guide bar actuated by a cam or equivalent mechanism may be used instead of a roller. Specifications 339,679, [Class 120 (ii)], and 529,150 are referred to.

Abstract: 424,318. Paper - folding apparatus. AUTOMATIC AKT. - GES. FUR AUTOMATISCHE DRUCKMASCHINEN, 143, Alte Jacobstrasse, Berlin. May 16, 1934, No. 14854. Convention date, May 16, 1933. [Class 100 (i)] Apparatus for folding paper or other like material in zig-zag fashion comprises swinging levers 2 carrying web-feeding devices and a mouthpiece through which the web passes and over the edge of which the web is creased or folded at each reversal of the swinging movement of the levers. The web 27, Fig. 1, passes from intermittently-operated feed rollers 28 over a roller 24 carried by adjustable levers 26, and between tensioning discs 21, 22. Two guide rods 19, 20 for the web are mounted between the pivots of the levers 2 so that the web passes through the pivotal axis of the levers to feed-rollers 9, 10, Fig. 1<a>, on the levers and a mouthpiece formed by steel bars 7, 8 toothed at their outer edges. The rollers 9, 10 are geared and spring-pressed together and are driven to feed the paper as the levers 2 swing to-and-fro by gear wheels on their spindles engaging teeth on one of a pair of fixed arcuate rack-bars 45, 46 and coupled to the spindles by suitable freewheel devices. Adjustably-mounted on the bars 45, 46 near to the ends of the swing of the levers 2 are creasing or folding devices, each comprising a bar 60, Fig. 8, on which is pivoted at 69 a triangular folding-bar 68. The spindle 69 is spring-controlled so that normally the bar 68 remains with its long face horizontal, and at one end carries an arm 72 with a roller 73 at its extremity. The bars 60 is adjusted along the bars 45, 46 by gear wheels 65 thereon engaging racks 47 on the under surface of the bars 45, 46. The levers 2 are oscillated from a camdisc 32 on a shaft 31 through a linkage 36-43, the connection between the links 38, 42 being adjustable so as to vary the swing and therefore the feed of the paper by the rollers 9, 10. A rod 87 pivoted to a link 88 and to a bell-crank lever 85 on the levers 2 is normally situated so that its upper pivot is coaxial with the pivots of the levers 2. At the ends of the swing, the bell-crank lever 85 is actuated from a cam 76 on the shaft 31 through links 80-83 so as to move the rod 87 along the levers 2 and cause one part of its forked end to engage the roller 73 and tilt the bar 68. The paper 27 is thus creased sharply over the mouthpiece 7, 8 by the bar 68 so that when released it drops with its edge folded. The upper faces of the bars 60 are grooved to accommodate the toothed ends of the mouthpiece-bars 7, 8.
