Description

Technical Field

[0001] This utility model belongs to the field of tape processing technology, specifically relating to a slitting device. Background Technology

[0002] Butyl sealing and waterproofing tape is a self-adhesive waterproof sealing tape that is made primarily of butyl rubber, combined with other additives, and processed using advanced technology. It exhibits strong adhesion to various material surfaces and possesses excellent weather resistance, aging resistance, and waterproofing properties. It provides sealing, shock absorption, and protection for the surfaces of adhered objects. Butyl sealing and waterproofing tape is completely solvent-free, therefore it does not shrink or emit toxic gases. Because it is permanently non-curing, it exhibits excellent adaptability to thermal expansion and contraction and mechanical deformation of the adhered surfaces, making it a highly advanced waterproof sealing material.

[0003] Butyl sealing waterproof tape needs to be slit during the manufacturing process. In the prior art, Chinese patent with publication number CN221416761U discloses a butyl waterproof tape slitting device. This prior art can slit tape rolls into different lengths, but it requires manual adjustment of the tape roll position during use, which is inconvenient. Utility Model Content
