Problems solved by technology

[0013] Therefore, when mass-producing a pressure-sensitive adhesive tape in which the allowable amount of a solvent contained in a coating agent such as a pressure-sensitive adhesive is strictly limited and the allowable amount of the solvent is set to a low value , such as when producing pressure-sensitive adhesive tapes for medical use on a large scale, conventional drying equipment has a problem in that the length of the linear transport path for transferring the tape substrate must be very long and the entire equipment becomes large

Embodiment Construction

[0040] Hereinafter, embodiments of the present invention are described with reference to the drawings.

[0041] Such as figure 1 As shown in , a manufacturing facility 1 for manufacturing a pressure-sensitive adhesive tape includes a feeding device 10 that accommodates a roll (roll) R, and a strip-shaped tape substrate T in the feeding device 10 Wrapped around said reel R, and said feeding device 10 feeds the tape substrate T from the reel R along the length direction of the tape substrate T; a coating device 20, said coating device 20 applying pressure sensitive adhesive agent (coating agent) S is coated on the tape substrate T fed from the feeding device 10; coating agent S; and a tape rewinding device 40 that rewinds the tape substrate T, wherein the drying of the drying device 30 is completed in the tape substrate T as the reel 400 is rotated. Dry processing. In other words, the drying apparatus 30 according to the present embodiment is utilized as a part of the pressur...

Abstract

A drying apparatus for manufacturing a pressure-sensitive adhesive tape in which a pressure-sensitive adhesive layer is formed on a strip-shaped long tape base material is provided. The drying apparatus dries coating agent coated at least on one surface of the tape base material. The tape base material that is transferred in a lengthwise direction thereof is spirally wound around a cylinder body from one end side of the cylinder body to the other end side of the cylinder body in a slidable state. The cylinder body is formed with a plurality of air holes on an entire circumferential wall thereof, around which the tape base material is spirally wound, the air holes through which warm air or hot air flows from the inside of the cylinder body to the outside of the cylinder body. The drying apparatus for manufacturing the pressure-sensitive adhesive tape can reliably dry the coating agent on the tape base material without increasing the drying apparatus in size.

Description

[0001] The disclosure of Japanese Patent Application No. 2009-253758 filed on Nov. 5, 2009 including specification, drawings and claims is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a drying apparatus for producing a pressure-sensitive adhesive tape in which a pressure-sensitive adhesive layer is formed on a strip-shaped elongated tape substrate, and the drying apparatus dries A coating agent such as a primer or a pressure sensitive adhesive coated on a tape substrate is dried. Background technique [0003] A pressure-sensitive adhesive tape is provided for medical use or office use, in which a pressure-sensitive adhesive layer is formed on a strip-shaped elongated tape base material. [0004] Depending on the use of the adhesive tape, the adhesive tape has different materials or compositions of the tape substrate or a pressure-sensitive adhesive layer. Each tape is manufactured by a drying process that dries,...
