Claims (1)

[Scope of claims for utility model registration] 1. Breaking lines such as perforations made for each unit of use 3.
a pair of feed rollers 6 that rotatably support a roll 1 wound with a continuous thin film product 3 to be used by cutting off the roll 1, and feed out the continuous thin film product 3 of the roll 1;
, 7, and rotates the feed roller 6.
Reference numeral 4 denotes an automatic feed-out type roll holder configured to be automatically controlled to feed out the length of one use unit each time one use unit of the thin film product 3a of the continuous thin film product 3 fed out by the feed rollers 6 and 7 is cut. A tension roller 6 for the continuous thin film product 3 is placed at a certain distance ahead of the feed rollers 6 and 7.
', 7' are installed, and a motor for rotationally driving the tension roller 6' is installed.
Drive control is performed to apply tension to the continuous thin film product 3 so that the break line 3b of the continuous thin film product 3 that has passed through the rollers 7 is separated before reaching the tension rollers 6' and 7'. 6', 7'
An automatic feed-out type roll holder characterized in that a detection mechanism 16 for detecting the presence or absence of the continuous thin film product 3 fed out from the tension rollers 6' and 7' and controlling the drive of the motor is installed at the front position of the roll holder. . 2. The feed rollers 6, 7 and tension rollers 6', 7' described in claim 1 of the utility model registration claim can be fixed by stopping the rotation of the feed rollers 6, 7, or by stopping the rotation of the tension rollers 6', 7'. By increasing the speed, the continuous thin film product 3 is separated so that the break line 3b of one usage unit of the continuous thin film product 3 that has passed through the feed rollers 6 and 7 is separated before reaching the tension rollers 6' and 7'. An automatic feed-out type roll holder characterized by controlling the circumferential speed difference that applies tension to the roll holder. 3. On the exit side of the tension rollers 6', 7' described in Claim 1 of the Utility Model Registration Claim, there is a stopper part 5c for closing the exit part and a handle formed by cutting out the approximate center of the stopper part 5c. The guide 5 is provided with a pool portion 5b having a widening shape that pools the length of one usage unit of the continuous thin film product 3 sent out from the outlet 5d and the tension rollers 6' and 7'. Automatically feeding roll holder.
