Description

Technical Field

[0001] This utility model relates to the field of FFC production equipment technology, and in particular to a double-sided adhesive applicator. Background Technology

[0002] During the production process of FFC, depending on actual needs, adhesive needs to be applied to one or both sides of the product. Previous adhesive application equipment was only for single-sided application. If double-sided adhesive application was required, it had to be done in two separate processes, resulting in low processing efficiency and failing to meet production demands. In addition, previous adhesive application methods could only apply single strips of adhesive. If multiple strips of adhesive were required on the product, it could only be done in multiple steps or with multiple adhesive application units, leading to low efficiency or high costs. Therefore, improvements are needed. Utility Model Content
