Abstract: 10,530. Grover, G. B. May 5. Feeding webs.-In a cutting-out press for heel lifts and other articles, the material to be cut is fed into position by a reciprocating element adjustably pivoted in a guide of an oscillating actuating-arm, such guide being concentric with the finishing position of the feeding- element so that this position is maintained approximately constant notwithstanding variation in the length of feeding-stroke. Yielding pressers arranged at the sides of the feeding- element serve to hold the material in position during the feed. Preliminary means may be provided for cutting the material into strips and for feeding these strips into position to be engaged by the feeding-means of the cutting-out press. The material to be cut into strips is fed by pairs of rolls 3, 17, Fig. 2, from a table 1 provided with a lateral gauge 2. The cutting- mechanism 18 is mounted on the shafts of the feed-rolls 17, and the lower of the feed-rolls 3, 17 are carried by spring-raised brackets. The severed strip then passes between feed-rolls 21 and over a telescopic table to a fixed table 27, Fig. 2, where it is in position to be engaged by the mechanism for feeding it to the cutting-out die. The rolls 21 are of narrow width or of spherical surface to allow for a slight alteration in the direction of movement of the material. The telescopic table comprises hinged portions 23, 26, which are adapted to slide relatively to each other and provide continuous support for the strip for all relative positions of the feed mechanisms. A spring guide 41 serves to direct the strip against a guide 41<a> on the table 27. The strip is then intermittently fed by fingers 74, Fig. 1 (with detachable points 82), adjustably pivoted in the slotted part 83 of a camoscillated arm 76. The slot 83 is concentric with the forward position of the feed-points 82, and the extent of feed is determined by the adjustment in the slot 83 of the fingers 74. The feedpoints 82 coact with the plate 89 in effecting the feed, and spring-raised fingers 91 control the work when released from the points 82. A guide 167, Fig. 2, is adapted to coact with the guide 41<a> and is connected for simultaneous adjustment with the gauge 2. Spring guides 181 serve to deflect from the remainder of the sheet the strip severed. The general arrangement of the machine is such as to ensure that the work shall be fed by the intermittent feedmechanism immediately it leaves the continuous feed-mechanism, and the necessary adjustments are provided to allow for the feed in accordanþe with the size of the articles and length of strips cut. The rolls 21 are adjustably mounted on a bed which also supports a head carrying the rolls 3, 17. This bed may be adjusted to and from the dieing-mechanism to allow the strip to be completely cut before passing to the dieing-mechanism. Independent adjustment of the support of the rolls 21 is provided to bring into coincidence the end of the continuous feed and the beginning of the intermittent feed. The table 27 with the intermittent feed-mechanism is adjustable to and from the block 28. All the feed-rolls are geared to rotate at the same peripheral speed, and the rollers 21 may be dispensed with.
