Description of drawings
Fig. 1 is each step that the present invention production method will be described;
Fig. 2 is that a coating is separated cutaway view, therefrom can see the method for making of the present invention;
The specific embodiment
We come with the aid of picturesly one now, and the inside comprises each step of the present invention production method, also has practical in process of production technological means simultaneously
These are flow processs of the present invention: there are two parts to constitute skin, and web, or scheme layer, this means their another less relatively thickness of size.This two-part distinguishing feature is that elasticity is fine.Have bigger resilient characteristic part we be called " distortion part "; The less part of elasticity is known as " constructional delails ", needs it is pasted on the distortion part that is stretched.
Constructional delails is normally made with leather.We have studied the performance of this block structure part, and mechanical strength and hardness mainly are in its surperficial plane (smooth place) or stretching/compression on its tangent direction.This constructional delails resistance to deformation under perpendicular to the strong pressure on surface.But we make this constructional delails a sinuousness arranged than higher performance.This constructional delails also combines the speciality of mechanical strength and elastomeric material.With respect to distortion part, characteristics such as structure has presented mechanical strength zero point, and tolerance is strong, and hardness is strong.But the distortion part has elasticity characteristics preferably.We use " Bengaline earlier

", perhaps corresponding
Figure BPA00001320392100032
Prepare such distortion part 1.Constitute lining with this distortion part, it may have the braiding of device or fancy.
At step 1 (I), distortion part 1 is to seek preassigned pattern on the basis of the 3D shape of in the past cutting; That is to say that according to its strain function, it will be on constructional delails
Then distortion part 1 is placed in the machine and constructional delails 10,, insert distortion parts 1 and lock seaming with 11.According to the characteristics, particularly its resilient characteristic of distortion part, come with tension force F stretching (Step II).
This strand tension force F must guarantee that dynamics is lower than the intensity of the unlikely fracture that can bear of distortion part.
A face of distortion part 1 will spray (Step II I) with the spraying equipment 12 that is fit to.Preferably use the more intense glue of adhesive bonding property, it has lower susceptibility, and condition effect is following is changed to minimum in the humidity of environment and temperature etc.It is met water and meets heat and all do not have telescopic variation; It can be The type of (neoprene), or with other materials of its equivalence, but should preferably pay attention to environmental protection and not influence healthy material.
Meanwhile or before, we will prepare and cutting structure part 2, it is to be made by leather or similar with it material.This material will have the shell of health and 3D shape simultaneously.A face of constructional delails is applicable to distortion part (step IV), and its adhesives starching step is identical with before distortion part 1.In this scheme, the part of constructional delails 2 is made by leather, about the application of the adhesives on surface, preferably uses " velours " (velvet).
Distortion part 1 and previous constructional delails 2 are superimposed, and bonding they (step V); Distortion part 1 will remain extended state (step V).
In case glue solidifies, we just can stop tension force F to its application of force, have so just produced composite part 1+2; Need immediately it to be bent to required three-dimensional shape (step VI) this moment.Broken away from power F, distortion part 1 shrinks the specified form that become again this moment.But because the resistance of constructional delails 2 makes it can not become its original form fully again.The radian of composite part 1+2, the constructional delails 2 that guiding has rigidity under the effect that applies tension force; And the distortion part 1 that guiding has the elasticity speciality; This power also makes these two composite beds 1 and 2 be bonded together firmly each other.Consider the constructional delails 2 that is deformed part 1 constraint, the shape of crushed element bending will be positioned at the protruding side of constructional delails 2; And the distortion part will be positioned at recessed side.
To would you please also note that the effect of constructional delails performance is crooked work.
Next this composite part 1+2 will finish the assembling (step VII) of other constructional delailss.This program is to be realized by known a kind of technology, for example uses stitching process, pieces technology together, or the like.At the concrete leather of using of the leather part of constructional delails 2, for example, it needs a cylindrical shape roughly, and replenishes the also two ends of closed cylinder by leather 22; Just formed a bag 20 by such mode.With its accessory,, all be contained on the bag 20 then as handle 21 and zip.
In the stage of implementing, the flow process of Miao Shuing can be used present automatic industrial production technology before.Can use different equipment to cut, draw and stretch, bonding, the use of bonding coat and assembling, and need provide machinery to control/numerical control.Especially be out of shape the material of the required usefulness of part, for example cloth; Material can normalisation, and this material will have definite result of use; In other words, just can reach the 3D shape of expection.
We it will be noted that this method for making not only is applicable to little constructional delails and distortion part, also is applicable to big constructional delails and distortion part simultaneously at this.The surface is not subjected to the restriction of reality factor.
In the application program of above-mentioned leather part, thus obtained bag 20 will be a permanent three-dimensional shape, thereby not need the specific part of putting more energy into, and perhaps keep the part of framework, perhaps framework.With reference to figure 2, directly realize keeping shape by leather layer 2 (constructional delails), will spend 23 outsides that are placed on its shell.The part of distortion realizes (distortion part) by rubber-like organized layer 1, and its one side is used for constituting the back boxing of bag, and one deck glue has been used to bonding skin suede layer 2 and the layer of cloth 1 to pasting.The invention has the advantages that, each constructional delails and distortion part show as following three functions: first kind of function is terms of mechanics, the power of (for constructional delails) and compression under long-term resistance (for the distortion part) can obtain desired three dimensional shape.Second kind of function is to form a shell of tank (outer wall of bag) jointly.The third function is the outward appearance of bag or the back boxing of bag, the characteristic of (vision presents, sense of touch) of style that is embodied and style aspect.Under the effect of this two next-door neighbours' part, its these three function is remarkable.
Certainly, the advantage of the present invention is not only to be confined to above-mentioned example, from the framework of the present invention, can expanded scope, and enumerate many examples.
Especially, in the specific implementation process of production 3D shape, can exceed the leatherware field, realization can make different objects use, and perhaps creates industrial use.
Used material may with differing widely of describing before, sincerely invite two kinds of materials with distinct elasticity speciality.
