In an automatic loom having a suction device for drawing off and holding the weft end of a bobbin being transferred to the shuttle, the suction is supplemented by a mechanical brake which acts on the weft until the first pick has been laid and is released before the pick is beaten up. The suction device 4 carries a leaf spring 5 serving as one member of the thread brake, the other member being an arm 6 normally held up by a roller 7a on a lever 7 acted on by a tension spring 8 attached to a leaf spring 9. When bobbin changing is initiated, a shaft 1 turns the leaf spring 9 anticlockwise to turn the lever 7 in the same direction, the spring 8 transmitting the movement by acting as a strut. A recess 6b then drops on to the roller 7a allowing the arm 6 to rest on the leaf spring 5, on which the drawn -off weft now lies. The lever 7 is engaged by a latch 10 which is released by a striker 11a on the slay before the next beat-up is completed; the parts return to the positions shown under the action of the spring 8, the shaft 1 having meanwhile resumed its normal position. In another embodiment, the pivoted latch 10 is replaced by a vertically sliding latch. U.S.A. Specifications 2,845,957 and 2,872,948 are referred to.

Abstract: 1277904 Attaching ring tabs to end closures; shearing CROWN CORK & SEAL CO Inc 19 June 1969 [15 Oct 1968] 31002/69 Headings B3A B3U and B3W A ring tab which is to be riveted to a container end closure 214 by a pair of opposed punches 106, 194, is placed on the end closure 214 by a pilot 42. In one embodiment, a feed strip having a ring tab blank secured to it along one edge only is fed to the press, Fig. 1, and an end closure 214 positioned on an annular support 192. An upper die assembly 22 is lowered to cause the ring pilot 42, Fig. 6, having spring biased gripping fingers 68, 68<SP>1</SP> to enter an aperture in the ring tab blank and grip the ring portion of the blank. The outer periphery of the blank is temporarily gripped by spring biased fingers (144), (144<SP>1</SP>) (Fig. 12, not shown) which are retracted against the spring bias as the ring pilot 42 descends further to allow passage of the ring tab through the apparatus. The ring tab blank is severed from the strip by a punch 94 co-operating with a cutting edge 158 of a cutting insert 142. Upon further descent of the die assembly 22, the end closure 214 is engaged by fingers 36, the annular work support 192 being depressed against spring bias 204. When the end closure 214 is engaged by the ring tab 218, a lower punch 194 engages the end closure rivet which now extends through an aperture in the ring tab and into a bushing 108 which surrounds an upper punch 106 having its one end normally spaced from the end of the bushing 108. Thereafter the bushing 108 is forced upwardly compressing an O-ring positioned between the upper heads of the punch 106 and bushing 108 until the punch and bushing ends are coplanar. The rivet is thereby allowed to be deformed laterally. When the end closure 214 is initially engaged by the ring pilot 42, the latter is forced upwardly against spring bias 48 within an aperture 40, the fingers 68, 68<SP>1</SP> being cammed inwardly by the walls of the aperture 40 to cause the ring tab to be released. In another embodiment (Figs. 14 and 15, not shown), the ring tab blank 218 is frictionally engaged by a ring pilot (234) passing through the one aperture of the blank and an upper punch (242) passing through the other aperture. The punch (242) is depressed against spring bias (248) within a bushing (244) until the bushing and punch ends are coplanar when the end closure 214 is engaged by the descending assembly 22.
