JPH071382A - Cutter for roll base paper or film - Google Patents

Abstract

PURPOSE:To enable it to cope with any rewinding failure in a material roll due to blocking in use of nondetective alone as cutting it after leaving a defective part, consisting of a blocking portion of the material roll, behind by attaching a blade to a supporter not caning out to one side from a cutting edge, and cutting the material roll as rewinding it. CONSTITUTION:When a reinforcing undercoat is applied to a film, this undercoat is overflowed from the applied surface, and if it is further transferred to the backside, there is such a case that blocking has occurred. In consequence, a material roll becomes impossible to lee refund. In this case, a blade 2 is attached to a supporter not coming out to one side from a cutting edge. In addition, a roll 3 and a spring 6 are additionally installed in this supporter 5, and a position of this blade 2 is properly adjusted. In succession, the blade 2 is pressed to the material roll 1 with proper force, cutting this material roll 1 as rewinding it. With this constitution, a defective part consisting of a blocking part of the material roll 1 is left behind from cutting, and a nondefective alone is used as cutting it.

Description

[Detailed Description of the Invention] I think that all the companies that currently handle films (laminating, printing, bag-making companies, etc.) have the problem of "parts with scratch glue (blocking)". For example, in order to strengthen the adhesive strength between aluminum foil and PE laminating, if the undercoat sticks out from both sides of the aluminum foil to the back side and transfers to the back side, blocking occurs and the original fabric cannot be unwound. If blocking ever occurs,
The speed of the machine is slowed down and the blocking part is peeled off by hand to assist the rewinding. When the treatment of ko is also impossible, it is expensive but only discarded.
In the past, there was a method of turning and cutting a raw fabric with a knife to make a notch corresponding to that length, but there was a way to cut it, but the support tool interfered and it could not be cut with a small winding diameter. As shown in FIG. 1, to the supporting tool 5 that does not protrude from the cutting edge to one side,
Attach the blade 2 and press it with the spring 6,
So that it doesn't go deep in. {Adjust it with the roll 3 (it can be adjusted also with the sensor)} Leave the defective part in the material part and use it while cutting only good parts, so you can also cut large diameter objects I will. Fig. 2 is a diagram showing the beginning of cutting with two cutting blades at two places and leaving the middle. If you want to use half of the original fabric, hang it on a conventional slitter machine and take two before use. However, if you use this device while cutting it in the middle, you can use it as it is, it will be a relief of the original defect and labor saving.
