Preferably, the support filler strip is a continuous strip structure or an interval strip structure.
Furthermore, in order to take the Kouzi adhesive product off the bottom supporting release film, the side, bonded with the Kouzi adhesive product, of the bottom supporting release film is a weak adhesive surface, and the side, bonded with the Kouzi adhesive product, of the top supporting release film is a strong adhesive surface.
Specifically, ask the end to be continuous rectangular structure from the type membrane, a plurality of openning are glued the product and are arranged from type membrane length direction along asking the end in proper order, the top from the type membrane with openning glue product one-to-one. The openning glue products can be arranged on the bottom supporting release film in the transverse direction or in the longitudinal direction.
Further, in order to facilitate separation of the gum product from the top release film in a subsequent process, the top release film has the same contour shape as the gum product, and the top release film is provided with a hand tearing part extending outwards from the edge. After the product is pasted on the frame of the product, the top release film is taken down through the hand tearing part.
In order to achieve the supporting effect, the height of the supporting cushion strip is 1-5 times of the sum of the thicknesses of the adhesive product and the top release film.
Preferably, the height of the supporting gasket strip is 1.5 to 3 times of the sum of the thicknesses of the gum product and the top release film.
The invention has the beneficial effects that: according to the packing structure for preventing extrusion overflow glue from displacing and deforming, the supporting filler strips exceeding the thickness of the product are arranged on the two sides of the bottom supporting release film, the gap in the winding process is kept, the pasting area of the gum product is in a spaced state, and the problems of overflow glue and displacement deformation of the product caused by tension extrusion in the winding process can be effectively solved.
