Embodiment Construction

[0010] As shown in the figure, press the leather sheet 1 and the pressed leather sheet 3 on the two pieces of leather that need to be combined, and use a peeling knife to cut the meat surface of the two leathers into a slope 4 of the leather flesh surface layer, and smooth the pieces to no Thickness, the fiber width of the flesh surface of the peeled leather should be controlled at 10mm; peeling must have a slope, and the pneumatic grinding wheel is used to remove the surface coating sanding layer 5 of the pressed leather stubble, which not only achieves the purpose of removing the coating, but also does not damage the leather fibers. . Then adopt high-frequency bonding technology to bond, first apply the leather treatment agent once on the upper pressure leather slope 4 and the lower pressure leather sanding layer 5, remove oil stains and impurities, then apply the adhesive twice respectively, enter The vacuum vulcanizer is heated for 6 minutes, and the temperature is control...

Abstract

This invention relates to a seamless adhering technology characterizing in chopping the edges of the meat sides of two sheets of leather being combined as one to a 10mm wide slant one and chopping them steadily to thickless finally, removing the coat with stubbles on the surface of the pressed leather with a pneumatic grinding wheel, ahearing them with a high cycle seamless adhering technology to be heated for 6 minutes in a vacuum sulfurizing machine under 60 deg.C and adhering a layer of thermal reinforcing material at the joint place of the meat sides.

Description

technical field [0001] The invention relates to the field of leather and product processing, in particular to a technical method for splicing leather sheets. Background technique [0002] At present, in the bonding of leather and products at home and abroad, the method of pressing stubble and stitching is mostly used, that is, one piece of leather is pressed on another piece of leather, and one to three lines are drawn at the overlapping place. Its disadvantage is that it is easy to have a stalk at the overlapping place, which affects the appearance of the product. Contents of the invention [0003] The present invention aims to solve the problem that the stubble and thread-trapping leather bonding method has a protruding stalk at the overlapping place that affects the appearance, and a high-frequency seamless bonding technology is invented to bond two disconnected pieces of leather. . [0004] In order to solve the above technical problems, the technical solution adopte...
