Abstract

PURPOSE:To soften the impact in drop of an iron core by reducing the difference of drop in the feeding and receiving passages of the iron core by arranging a stopper which is turnable and has an iron core receiving cut part in close to the edge part of a magazine rail for introducing the iron core and an iron core feeding arm which has an iron core receiving part in the lower part of the stopper. CONSTITUTION:An arcuate guide 4 is formed downward at the edge part of a magazine rail 3 for introducing an iron core 8 in which a paper tube is inserted, and a nearly fan-shaped stopper 1 having an iron core receiving cut part 2 having the shape for the fitting with the sectional shape of the iron core 8 is installed in the vicinity of the guide 4 so as to be turnable. Further, an iron core feeding arm 7 is installed at the position where the stopper 1 turns downward and stops and the iron core 8 separates from the stopper 1, and the iron core 8 is delivered to the receiving part 7a at the top edge, and then supplied onto a drum, and the taking-up onto the paper tube can be continued.

４２−５４８５）。[Conventional device] Conventionally, a long film is continuously fed, wound onto a paper tube in fixed lengths, and when it reaches a predetermined amount, the film is automatically moved to the next one without stopping the film feeding. A winding device is known (for example, Japanese Patent Publication No. 42-5485) which continues winding by supplying a new paper tube and also sends out a fully wound product.
