Abstract

523,376. Feeding webs. HARRIS-SEYBOLDPOTTER CO. Jan. 4, 1939, No. 270. Convention date, Jan. 5, 1938. [Class 100 (i)] A mounting for the supply rolls of printing and other machines comprises a pair of spiders 52 with roll supporting spindles 53, 54 spaced apart a distance less than the diameter of a full sized roll 6, the spiders being carried by the longitudinal members 49, 50 of an open centred rectangular frame, the end members of which have trunnions 44 for rotatively supporting the frame in the side frames 2 of the machine. The spiders are adjustable along the members 49, 50 in accordance with the width of, the rolls by means of spindles 74, rotatable by a key applied to either end, and formed with pinions 76 engaging rack teeth 73 on the members 49, 50. The frame is also adjustable axially for side register of the web by means of a screw engaging the end of one of the trunnions. One of the roll supporting spindles of each roll is slidably mounted in its spider to allow insertion and removal of the roll by means of a screw rotatable in the spider and threaded into the end of the spindle, a gravity pawl engaging a ratchet wheel on the screw to prevent accidental turning of the screw in the direction to withdraw the spindle. For turning the frame to bring the rolls from loading to running position, each trunnion 44 has secured thereto a gear wheel 101 engaging a pinion 102 driven by worm gear 104, 105 from a shaft 103, the two shafts 108 being connected by bevel gears to a cross shaft 111 adapted to be driven by a motor 114. The unwinding of the roll is controlled by a number of endless leather belts 40 passing round a roller 37 driven by the press, through a differential gear 35, and round pulleys 39, independently mounted on weights 120 slidably guided by means of grooves 125 on guide bars 124 carried by fixed brackets 122. Specification 417,499 is referred to.
