Description

Application film attaching the film having cut off lines made on a working roll to film base

The present invention relates to a film attachment device for attaching a film having a perforated line to an adherend, and more particularly, even if a soft film having a low hardness, it is easy to give a cut line of a desired interval and direction to the film. In addition, even if the film is wound in rolls, the cutting line can be arbitrarily cut, and the gap between the cutting lines can be prevented by changing the elongation. Therefore, as a result, adhesion to the adherend becomes easy. The present invention relates to a film applying apparatus for attaching a film having a perforated line to an adherend on a work roll capable of improving reliability in application.

Various tapes or films (hereinafter collectively referred to as films) attached to the adherend by applying an adhesive to one side, such as a scotch tape or film, cellophane tape or film, paper tape, etc., are commonly used and accessible in the vicinity.

Such a film may be used as a whole by the user after being released into a product, or may be used after being cut by a predetermined unit length, or after the film is previously attached to an adhesive (an object to which the film is attached). It is also released as a product with adhesives. Here, an adherend can refer to stainless steel, aluminum, a steel plate for painting, and the like.

In general, considering that the film is used by a predetermined unit size, the film is provided with a cutout line when the film is manufactured, and the film with the cutout line is released as it is rolled up several times by a separate roll or Or it is used at the time of the adhesion process with a to-be-adhered agent.

However, if the film has a low hardness, that is, a soft material such as PVC, if the film is rolled into the roll unit after the perforation line is put in the film, the tensile force is generated during the winding, so that the perforation line is naturally cut off or elongated before use. Due to the change of the gap between the cutting line arbitrarily is very likely to occur because it causes a problem that is difficult to apply the product.

It is an object of the present invention, even in a soft film having a low hardness, it is easy to give a cutout line in a desired interval and direction to the film, and even if the film is rolled in roll units, it is possible to prevent a phenomenon that the cutout line is arbitrarily cut out. However, the phenomenon that the gap between the perforations is arbitrarily distorted due to the change in elongation can be prevented, and as a result, the film having the perforations formed on the work roll can be easily attached to the adherend and improve the reliability of the product application. It is to provide a film attachment device to attach.
