Abstract

PURPOSE: To obtain a variable radius-circumferential length drum for feeding a belt-shaped article, by applying focusing force to a radially divided annular both toward the center of a circle, further forming its inside curved face to sloped shape, slidably contacting an inverted conical base to said curved face and arranging said conical base vertically movable.
CONSTITUTION: Focusing force is applied by a focusing ring 4 toward the center of a circle to an annular body 2 provided with radially divided numerous vertical walls 22, further their inside curved face is formed to sloped shape, and an inverted conical base 3 slidably contacted to said curved face is formed vertically movable. For instance, when adjustment of an outside diameter is performed, the focusing ring 4 is left in an opening state and a diameter adjusting cylinder 5 is rotated and lowered along a strut 11, then a tapered face 37 of the inverted conical base 3 pushes out a group of the annular body 2 toward the outside by equal distance. Accordingly, the outside diameter of a drum consisting of the continuous vertical walls 22 is enlarged to increase its circumferential length. In this way, the annular body 2 can be expanded and contracted in a fine amount by a slight amount of vertical motion of the inverted conical base 3, thus the change of a radius or the like can be easily performed.
