Abstract
PURPOSE: To perform fine adjustment of speed for feeding a belt-shaped article or the like with a feed drum, by forming opposite directional threads on bolts, screwing the bolts into two semicircular discs, turning the both bolts and changing relative distance between the both semicircular discs.
CONSTITUTION: Two semicircular grooves 24, one of which is reversely threaded, are provided in two semicircular discs 2, and bolts 44 with their threads in an opposite direction to each other further with an integrally fixed worm wheel 4 are screwed into said two semicircular discs 2. And they are constituted in such a manner that the both bolts 44 are rotated by a worm 5 housed in a worm container disc 52 to change relative distance between the both semicircular discs 2. For instance, when circumferential length is increased, the worm 5 is rorated by using a screw driver to turn the worm wheel 4, then the rotation of the both bolts 44 causes the left and right semicircular discs 2 to be a slight interval apart. In this way, though a gap is slightly produced between circular center walls 22, 32, the circumferential length can be increased without causing a problem in practical use.
