723,934. Perforating and severing webs. FULK, J. B., and ROSS, F. A. June 27, 1952, No. 16213/52. Classes 31 (1) and 31 (2). [Also in Group XV] Apparatus for making manifold form wherein a plurality of transfer strips 6, Fig. 18, are interleaved with a plurality of record strips 10 and wherein each record strip is provided with a strip 145 containing a row of pre-punched holes 11 extending along one or both edges thereof to enable the strips to be guided and fed, comprises an endless belt or belts 16 provided with projections which are adapted to enter the holes 11, means being provided for moving the belt intermittently and means also being provided for punching apertures 30, 31, Fig. 14, making cross perforations 32, and for inserting staples 33, 34 in the strips while they are stationary, after which operations, the strip or strips 145 are severed. Work-feeding.-The belt or belts 16 pass over wheels 20, 21, the wheel 20 being mounted on a shaft 46 which is rotated intermittently by means of a rack-and-pinion 48, 50 and pawl and ratchet mechanism 53, 54. The rack is reciprocated by means of a crank 61 fixed to a shaft 62 driven from a motor 76 and the throw of the crank-pin 66 is adjustable radially so that the distance between the cross perforations 32 can be varied in accordance with the length of form desired. The shaft 46 is held stationary between intermittent feed movements by means of a braking device, Fig. 6 (not shown). The strips are fed to the belt or belts 16 in assembled form from a collating machine 15 such as described in U.S.A. Specification 2,100,776 and from which extends a shaft 105 driven from the motor 76. Punching.-The holes 30, 31 are punched in the strips by means of a punching head 25 which carries a plurality of punches (103, Fig. 17 (not shown)) and is reciprocated vertically by means. of a pair of eccentrics 97 mounted on a shaft 96 which is rotated by means of gearing from the shaft 62. Cross-perforating.-The strips are provided with the cross perforations 32 by means of a blade (91, Fig. 10 (not shown)) carried by a head 26 which is reciprocated vertically by means of eccentrics 82, 83 carried by a shaft 80 which is rotated by means of gearing from the shaft 62. Severing.-The strip or strips 145, Fig. 14, containing the holes 11 are each severed at the completion of the punching, cross-perforating and stapling operations by means of cutter wheels 135, 136 driven by a motor 137. Shearing.-The forms may be cut into desired lengths by means of a shear blade 151 which is actuated by eccentrics 152 mounted on a shaft 153 which is driven from the shaft 62 by means of a chain 154 and sprocket-wheels.
