Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an apparatus for manufacturing wound tapes, emergency bandages, etc.

<Prior art> To manufacture a bandage such as wound tape, a band-shaped adhesive tape unwound from a roll is stretched horizontally on the processing part of a device, and this series of tapes is spread across the width of the bandage. The tape is transferred intermittently, and from the tape delivery side, the first processing section supplies the wound dressing member, and the downstream side of the second processing section supplies the release paper, and furthermore, a shearing type cutter is installed on the downstream side to adjust the width of the bandage. Cut and packaged.

<Problems to be Solved by the Invention> However, in conventional manufacturing equipment, a band-shaped adhesive tape is stretched horizontally, and this tape is moved intermittently to form rows of small holes on the film surface and to form holes on the film surface. Since the supply and cutting of the scratching member and release paper are performed intermittently, there is a limit to the speed of intermittent feeding, and productivity is low, usually around 350 sheets/min, which is one of the reasons for the high cost. There is. Moreover, in this type of apparatus, the adhesive tape is sent under a certain tension to each processing section for processing, so the adhesive tape has the disadvantage of elongation due to the tension. To reduce tape stretch, usually
A stiff, hard film such as vinyl chloride is used, but the problem of elongation remains unsolved.

Recently, there has been a strong demand among consumers for a bandage using an ultra-thin film, but with conventional devices, the thinner the tape, the more it stretches, making it difficult to manufacture. Therefore, in this invention, an adhesive tape is passed around the outer periphery of a drum having air intake holes on the outer periphery to attract it, and while the tape is transferred together with the drum, a scratching member and release paper are supplied to the adhesive surface. To provide a new bandage manufacturing device that completely eliminates the stretching of the adhesive tape and makes it possible to manufacture bandages using ultra-thin tape by cutting the adhesive tape at equal intervals while it is adsorbed on a drum. purpose.
