Tape suitable for circulating film tearing devices

Abstract

An adhesive tape suitable for a reusable film-tearing device includes an adhesive layer, a protective film layer adhered to the outer peripheral surface of the adhesive layer, two reinforcing layers, and a sensor. The adhesive layer includes an extension section and two end sections located at opposite ends of the extension section, one end section being adhered to the other end section, making the adhesive layer loop-shaped with its ends connected, and the outer peripheral surface of the adhesive layer being viscous. The reinforcing layers are respectively adhered to the end sections along the normal direction of the adhesive layer. The sensor is sandwiched between one of the reinforcing layers and the corresponding end section. The end sections are the initial sections for application; by sensing the position of the sensor, it is possible to determine in advance whether the tape is about to run out, thus allowing for pre-emptive replacement and further reducing waiting time, thereby improving operational efficiency.

Claims

1. A tape suitable for a recirculating film-tearing device, comprising: an adhesive layer including an extension section and two end sections located at opposite ends of the extension section, wherein one end section is adhered to the other end section, such that the adhesive layer is connected end to end in a ring shape, and the outer peripheral surface of the adhesive layer is adhesive; a protective film layer adhered to the outer peripheral surface of the adhesive layer; two reinforcing layers respectively adhered to the end sections along the normal direction of the adhesive layer; and a sensing element sandwiched between one of the reinforcing layers and the corresponding end section, or sandwiched between the end sections, wherein the sensing element can be sensed and positioned.

2. The tape as described in claim 1, suitable for a reusable film-tearing device, wherein, The sensor is made of metal.

3. The tape as described in claim 1 or 2, suitable for a reusable film-tearing device, wherein, The adhesive layer and the reinforcing layers are transparent.

4. The tape as described in claim 1, suitable for a reusable film-tearing device, wherein, The adhesive layer and the reinforcing layer form two fixing points located on opposite sides of the sensing element along the circumference of the adhesive layer, and each fixing point is engaged with the reinforcing layer and the end segments.

5. The tape as described in claim 4, suitable for a recirculating film-tearing device, wherein, Each fixing point extends along the width direction of the adhesive layer and welds the reinforcing layers and the end segments.
