With the method for packing articles with soft sheath and use the equipment of this method and the product of manufacturing
The present invention relates to a kind of method, make the product of gained in this way in particular for constituting the chair accessory of back, seat surface or handrail, also relating to packing articles with soft sheath, and the equipment that uses this method.
The chair accessory generally includes rigid support and elastic layer, particularly foam of a suitable shape, and it is the outside that is fixed on this support by cover, rigid support (or being similar material) normally wooden or plastics, but also can be metal.
At present, cover is to make with the pieces of fabric that is cut into the accessory shape, around have a very wide surplus limit.Each cover can be sealed by its edge in this surplus limit, can make it wrinkling and can impose pulling force around accessory, with ensure said cover be placed on its accessory around; Then, said surplus limit is fixed on the rigid support, or at the back side of rigid support, or on around it.Be supported under the wooden situation this fixing normally guarantee in the support by fabric is clipped in.Under the metallic support situation, thisly fixedly guarantee that by a kind of wooden stay wooden stay is inlayed along the accessory limit, so that clamp the surplus limit of fabric.
There are some important shortcomings in this packaging method.At first, need a large amount of manual operationss of manually finishing with continuous pulling force placement cover, and fixedly the operation of cover will be by clamping or finishing by means of wooden stay.Under the metallic support situation, it is long that these operate not only the time, and difficult, and require skilled especially.In addition, each pieces of fabric around the width on required surplus limit very wide, compare with the regular needs of parcel accessory and to have caused tangible waste of material; Often be to cut these surplus limits manyly, to dwindle the floating band of fabric, this practice has increased labour cost, and the danger that also has fabric edge to get loose simultaneously is unfavorable for the outward appearance of finished product.
The applicant's European patent EP 223, technology described in 312 has solved these shortcomings, it has mentioned a kind of method with packing articles with soft sheath, it is to make a cover that is used for covering the suitable shape of a face of article earlier, and has a surplus limit of a bending around this face or reverse side, then, with an elastic cord this cover is fixed, elastic cord is to use the boost line of closing along above-mentioned surplus side seam to fasten.Said elastic cord is tightened up and sealed, so that make said surplus limit wrinkling and around article or in the place near the back it is tightened once more.
Purpose of the present invention then is to provide a kind of method of improved wrap articles, and it is drawn by above mentioned technology, and this method is compared same convenience with this prior art, but range of application is wider.
For this reason, the present invention mentions a kind of method with packing articles with soft sheath, it is characterized in that comprising following means:
-to cut a block-shaped finished form with article consistent and the sheet of soft material on an additional surplus limit arranged on outline,
-on this surplus limit, make some boost lines, so that contain the stitch line of delegation in material and the stitching of delegation's plait externally together, between two lines a passage that stretches along said surplus limit along the formation of pieces of fabric edge;
-in sewing up passage, place an assemble line that assembles this line can be slided along this passage in inside, two terminations of line will grow, said assemble line comprises an electric lead that scribbles a kind of hot gluing material, this material is by heating the toughness that just can become with being lower than the temperature of sewing up boost line and soft material melting temperature
-again with pieces of fabric cover object above, allow surplus limit that assemble line is housed exceed the latter's outline,
-to draw said surplus limit in and apply the pulling force of opposed direction at the assemble line two ends along object edge, purpose is to shorten the length of the assemble line of putting into above-mentioned passage,
-to the lead energising,, and on around they are whole the edge on surplus limit is fixed in the support with the heat hot glueing material.
It is also noted that, use electric wire in conjunction with two elements at French Patent (FRP) FR1, be known in 049,710.But, in the described method of this patent, related to a technical field far apart with field of the present invention.In addition, it has also mentioned thermoplastic element's combination, and according to this and diverse ways of the present invention, electric wire is a simple heating element, and can not guarantee the connection of each element in other words.
At first, the technology described in this method and the European patent EP 223,312 is compared same convenience.In addition, according to this method, the edge of cover its all around on link and the latter's that fully fits shape with supporting.The range of application of this method is very wide.
At first, allow cover be attached in the very different support of some oneself states, simultaneously use a kind of assemble line in mode easily in fact.The hot gluing coating material of assemble line is the mixture by a kind of synthetic resin or a kind of synthetic resin, and they are to many materials for example metal, plastics, porous material (paper, cardboard, leather, timber ...) can both present adhesivity.
In addition, also have several occupation modes to adopt, so that the possibility of multiple parcel and combination is provided.
Like this, according to the first kind of occupation mode that is used to wrap up article with back relative with the front, adjust the position of assemble line, so that arrive back location after draw on surplus limit, the edge that allows said back constitute soft pieces of fabric is fixed in its support.
According to this occupation mode, the outline of cover, its all around on, all be fixed on the back of article.It is also noted that in this case, a convenient part of the present invention is that cover can directly be glued on the elastic layer of chair accessory to be wrapped, and do not need elastic layer fold to one with the rigid support place of its back at same horizontal plane.The unique conditional of regulation is to use a kind of hot gluing material that elastic layer is had adhesivity.Its all around on cover is fixed on the article back this method also can be used to wrap up the non-flat forms article, promptly have concave, convex ... the front and back of shape.The in fact available simpler mode of this parcel is finished: between the hot gluing operational period that said edge is glued on the article back, keep-up pressure all around at the pieces of fabric edge.
In addition, method of the present invention also can be used to wrap up the article that its back is non-linear profile, particularly is the part of concavity profile.
Available following more suitably mode is finished this parcel:
-on the edge of back, arrange a pin that with regard to the back, constitutes projection, vertical with the buckled zone of each concavity profile part,
-for each concavity profile part, before stitching is finished, on the pieces of fabric limit, dig a buttonhole, be positioned to and channel vertical.
-draw surplus limit in along the article edge, allow each buttonhole hold a pin and make the inside of assemble line against said pin.
Second kind of form of the present invention can also be wrapped up the article with a back with cover, and simultaneously this rear concatenated supported second.For this reason:
-on surplus flank side surface, adjust the position of assemble line along the pieces of fabric edge,
-support the back be abutted against article to second,
-by the heat hot glueing material, the back and second that the periphery of soft pieces of fabric is fixed on article is supported.
The third form of using then is to use the cover wrap articles in first procedure, afterwards these article is attached in the support.For this reason:
-on the surplus limit face relative, after drawing said surplus limit in, adjust the position of assemble line with the back,
-sealed assemble line termination after tension,
-article are placed in the support and to the lead energising so that article be attached in the said support.
At last, the method according to this invention has been equipped with the article of half trough rim periphery on can also wrapping up around having in front.For this reason, adjust the position of assemble line so that surplus limit arrives half trough rim position after drawing in, in the tension process, said assemble line is attached in said half trough rim.
As the means that can use said method, the invention still further relates to a kind of assemble line, comprising:
-heart yearn of being made up of electric lead scribbles a kind of hot gluing material,
-and shell that is woven into the hot gluing material fiber, this material with the adjoining temperature of the activation temperature of coating material under can be activated.
The invention still further relates to the chair accessory that some can obtain by the inventive method, comprise an elastic layer, a soft cover that covers the said front of accessory, cover comprise one around or from then on the front to the surplus limit of reverse side (said back) bending, said accessory is characterised in that cover contains an electric lead that fastens with boost line, to make boost line and be in order to close along above-mentioned surplus side seam, and cover be use stretch along lead and form the hot gluing material that viscosity connects between around edge, surplus limit and front or the back and bring fixing.
