Abstract

The present invention relates to a seamless binding technology for a leather product, which is characterized in that the edges of two leather meat surfaces, which need binding together, are cut into inclined surface-shaped edges by a peeling cutter, width is 10mm, and following sheets do not have thickness. The present invention has the following steps: sanding, binding and reinforcing, wherein an air sander is used for removing a coating of the surface of press stubbles of pressed leather in a sanding step; in a binding step, a high frequency seamless binding technology is used for binding the edges, the two leather meat surfaces are put in a vacuum vulcanizing machine to be heated for 6 minutes, and temperature is controlled to 60 degrees; in a reinforcing step, the meat surface of two leather binding points is bound with one layer of hot melting reinforcing materials. The present invention overcomes the problem that a beautiful appearance is influenced by bulged stalks occurring at folded points existing in stubble pressing and thread seizing type leather binding method, and the present invention is suitable for binding different leather and products (except for leather with embossment or bulge surfaces).

Description

A kind of leatherware seamless binding method
Technical field
The present invention relates to the machining field of leather and goods, is a kind of technological method of splicing between leather sheet and the sheet of being used for specifically.
Background technology
At present, both at home and abroad in leather and goods bonding, adopt presses stubble to seize the modes of line more, is about to a cladding and is pressed on another piece cladding, and its place of laminating seizes one to three diatom.Its shortcoming is that the place of laminating is prone to prominent stalk, and it is attractive in appearance to influence product in appearance.
Summary of the invention
The present invention seizes line formula leather bonding method for solve pressing stubble, and prominent stalk influence problem attractive in appearance appears in the place of laminating of existence, invents a kind of high frequency seamless adhesion technology of using, and two leathers of disconnecting are carried out the adherent technology.
The present invention is for solving the problems of the technologies described above, the technical scheme that is adopted is, a kind of seamless binding technology for leather product, comprise design variable and product standard etc. is input in the computer, by intelligent three-dimensional CAD computer aided design (CAD), best disconnected position and the best of calculating product laminate surplus, require to carry out rational severing according to computer.Its special character is, 1. peels, and the edge of two leather flesh noodles that needs are combined is whittled into inclined plane shape with the cutter of peeling, and width is at 10mm, along sheet to there not being thickness; 2. sand milling is removed a coating of being pressed leather pressure stubble surface with air sander; 3. bonding, it is bonding to adopt high frequency seamless adhesion technology to carry out, and goes into vacuum vulcanizing machine heating 6 minutes, and temperature is controlled at 60 degree, and high frequency adopts industrial frequency bands 27.2/40.68MHZ welding rapid.4. reinforcement, the flesh noodles in two leather abutting edges pastes one deck hot melt supporting material.
Technique effect of the present invention is to adopt technique scheme can realize a kind of do not have slit and firm leather bonding technology.
Description of drawings
Fig. 1 is the bonding structural front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is the leather of the present invention synoptic diagram of peeling.
Fig. 3 is that leather of the present invention is pressed stubble face-coating sand milling synoptic diagram.
In the drawings, press on 1 leather sheet, 2 bonding positions, 3 to be pressed leather sheets, 4 flesh side of a belt layer inclined-plane, 5 to be pressed leather sand milling layers.
Embodiment
As shown in the figure, press leather sheet 1 on two leathers that needs are combined, pressed leather sheet 3, be whittled into flesh side of a belt layer inclined-plane 4 with the flesh noodles of cutter with two leathers of peeling, to there not being thickness, the flesh noodles fiber width of removing from office of peeling should be controlled at 10mm along sheet; Peeling to have the gradient, adopts air sander to remove and is pressed leather to press stubble top coat sand milling layer 5, has both reached the purpose of decoating, does not damage leather fiber again.It is bonding to adopt the high frequency adhering technique to carry out then, on last pressure leather inclined-plane 4 and press down leather sand milling layer 5 place and brush one time earlier the corium treatment agent respectively, remove greasy dirt and impurity, brush twice tackiness agent then respectively, go into vacuum vulcanizing machine heating 6 minutes, temperature is controlled at 60 degree.The overlapping 8mm of two parts is carried out bonding position 2, and high frequency adopts industrial frequency bands 27.2/40.68MHZ, and welding is rapid.At last two leather abutting edges flesh noodles laminating one deck thermosol supporting material, both reached the effect of reinforcement, do not damage surface again, be unlikely to cause the leather loose side.Make leather really reach a kind of effect of seamless binding.

Claims (1)

1, a kind of leatherware seamless binding method is input to design variable and product standard etc. in the computer, by the three-dimensional CAD computer aided design (CAD), calculates the disconnected position of product and laminates surplus, requires to carry out severing according to computer; May further comprise the steps: peel, the edge of two leather flesh noodles that needs are combined, peeling with the cutter of peeling is whittled into inclined plane shape, width is at 10mm, along sheet to there not being thickness; Sand milling is removed the coating of being pressed leather pressure stubble surface with hand formula air sander, brushes a corium treatment agent, twice tackiness agent again; Bonding, it is bonding to adopt high frequency seamless adhesion technology to carry out, and goes into vacuum vulcanizing machine heating 6 minutes, and temperature is controlled between 60 degree; Reinforcement, the flesh noodles laminating one deck hot melt supporting material two leather abutting edges.
