Abstract
PURPOSE: To make possible multiple piece setting of winding shafts with a simple constitution by supporting the winding shafts in a plurality of positions on the concentrical circle of opposing rotary discs and power-turning the winding shafts turned to the specified positions thereby spreading the background curtain.
CONSTITUTION: Discs 14, 15 are turned by a drive device 49, gear 50, the gear 51 of one disc 14 of opposing rotary discs 14, 15, etc., after which they are stopped by the limit switches or the like which are closed by way of actuators at every set spacing of the winding shafts 19... removable from the shaft joints 20..., 21... provided at an equal spacing on the concentrical circle of the discs 14, 15, whereby the desired winding shaft 19 is positioned to the lowermost position. The gear 30 of the joint 20 corresponding to this winding shaft 19 intermeshes with the gear 31 coupled to a drive device 28 by way of a clutch 31, thereby turning the winding shaft 19 which had been detained of unnecessary turning by the sprocket 31, etc. through turning of the winding shaft 19 by the device 28 and hanging down the background curtain. Thus the multiple winding stems may be set with the simple constitution of not requiring any drive device for hanging-down for every winding shaft.
