Реферат: 150,915. Wood, H. May 10, 1919. Collapsible spindles and rollers; winding webs. -A collapsible spindle or roller, particularly for use as a winding-roller in paper slitting and rewinding machines, of the kind in which conical surfaces on an inner core engage conical surfaces on an outer segmental shell which is expanded by relative longitudinal movement of the core and shell, is provided with a lath adapted to be inserted between two adjacent segments of the shell to secure the material to the spindle, and a rotatable tubular cover is also provided to lock the lath and material in position. As shown, a core n is provided with conical flanges n<1>, n<2> engaging conical surfaces o<1>, o<2> on segments o which are guided by pins o<6>, o<8> and slots o<5>, o<7>, the pins o<8> having heads to retain the segments or. the core. The expansion and contraction of the spindle is effected by operating a nut o' screwed on to the core n. A sheet metal or other tubular cover q with a gap q<1> surrounds the segments o and when the paper is to he secured to the spindle, the cover q is turned to bring the gap q<1> opposite to a recess o<9> formed between two adjacent segments o. The ends of the paper strips are placed in the recess o<9> and a thin lath 11 is then inserted in the recess and the cover q turned to the position shown in Fig. 4. The lath is provided with an opening to receive a tool by which it is withdrawn from the recess prior to collapsing the spindle.
