Fig. 1 be one produce bag draw together the Pinch hands protective layer and with it be fixed to one its having of walking about down towards on the coiled material 2 of viscous layer 3 on the sketch map of device 1.Coiled material 2 with certain suitable manner as on the direction of arrow A, moving by means of belt conveyor or some similar facility.
Device 1 comprises that a protective layer coiled material 4 is wound on the storage belt wheel 5 and one or more strip material coiled material 6 is wound on the storage belt wheel 7.Protective layer coiled material 4 and strip material coiled material 6 be around the operation of the part of the periphery of rotatable pressure roller 8, for pressure roller, 6 of coiled materials within coiled material 4, and said coiled material 6 also pressure roller axially on apart from one another by opening.Protective layer coiled material 4 has the width identical with the coiled material of walking about 2 and is parallel to said coiled material and extends.In an illustrated embodiment, there are two strip material coiled materials 6 to be set to longitudinal edge with coiled material 4 apart from one another by opening.Pressure roller 8 is provided with the dome limit 9 that circumferentially extends on the position of each strip of material coiled material 6, two longitudinal edges of the relevant coiled material 6 with it in said dome limit are spaced apart.Be included in ultrasonic horn 10 in the ultra-sonic welded unit (not shown) and be disposed in the opposite on each bar dome limit 9, and protective layer coiled material 4 and strip material coiled material 6 are passed by between loudspeaker 10 and dome limit 9.Pressure roller 8 is mounted to such an extent that leave 2 one distances of coiled material of walking about protective layer coiled material 4 is being docked with tacky surfaces 3 on the coiled material 2 of walking about through after the loudspeaker 10.
Device 1 is operation in the following manner.
Protective layer coiled material 4 transports out from storage belt wheel 5 with suitable manner, is laid on the coiled material 2 of walking about by means of pressure roller 8, and the peripheral speed of pressure roller 8 is consistent with the speed of walking about of coiled material 2.Or drive pressure roller 8 or drive storage belt wheel 5 or driving the two can both make coiled material 4 advance.Also can on the direction that coiled material moves, in the downstream of pressure roller 8, be provided with a pair of pressure roller make walk about coiled material 2 and protective layer coiled material 4 both advance.Can make pressure roller 8 and coiled material 2 leave a bigger distance in this case suitably and make the downstream that to pressure roller compressing coiled material 4 it is pressed on the viscous layer of coiled material 2 upper surfaces.Strip material coiled material 6 also is transferred out from storage belt wheel 7 in a similar manner.The conveying of design protection layer coiled material 4 and strip material coiled material 6 is stretched these coiled materials slightly when advancing suitably.
The effect of the anvil face of ultrasonic horn 10 is played on dome limit 9, and can effectively strip material coiled material 6 be welded on the protective layer coiled material 4 when coiled material moves through loudspeaker 10, thereby produces that extend an in the vertical or long and narrow weld seam 11.The dome limit also is configured to and can produces a line of weakness 11 in the central authorities of seam 11.
After protective layer coiled material 4 is laid on the coiled material 2 of walking about, can wear or cutter sweep 14,15 cuts out finished product 12,13 or go out from said coiled material by means of suitable dashing.
Fig. 2 and 3 illustrates an example of the finished product 12 that cuts out from coiled material 2.Each layer of product adopts and to be used for recognizing that the same numeral of each coiled material recognizes among Fig. 1.Product 12 is exactly the part that cuts off from coiled material 2 like this, and 4 of protective layers and are being fixed strip material 6 with seam 11 on protective layer 4 on viscous layer 3.The position of strip material 6 is at part 16, the 17 Xing Cheng Pinch handss of seam 11 both sides.
As previously mentioned, the central authorities along seam make a line of weakness 18 when carrying out the ultra-sonic welded operation.When will removing the protective layer of one or both sides, need only just can protective layer 4 be torn in user Shou Chi Pinch hands 16,17 with little strength along line of weakness 18.In case protective layer 4 is removed, just the tacky surfaces of product 12 can be applied to required place.
Product shown in Fig. 2 and 3 for example may be the wound cover layer, at this moment except viscous layer 3, may comprise that also the absorbent foamed materials 19 of one deck is as polyurethane foam plastics and one deck impenetrable liquid but can see through the material 20 of steam as polyurethane film.Layer 3 can be made of runny elastomeric material of one deck such as silicon resin glue, and protective layer 4 He Pinch handss 16,17 can be made of polypropylene film.Pinch hands 16,17 not necessarily will have and protective layer 4 identical materials, but certainly, they should be made by welding material, make in the ultra-sonic welded process and can make line of weakness 18.The degree of depth of line of weakness 18 is preferably at least greater than half of the thickness of handling knob, and preferably Yan stretches Tong Guo Pinch sheet material 6 and enters protective layer 4 can easily be removed from viscous layer 3.Nature, line of weakness is also extensible by strip material 6 and protective layer 4, but way is also bad like this, hereinafter will illustrate.
Fig. 4 is the sketch map of known cover layers, and this cover layer comprises two stacked peel-able film 2l, 22.Bottom peel-able film 21 has a folding limit, comes Xing Cheng Pinch hands like this.For this cover layer one serious risk is arranged, promptly between stacked peel-able film 22 and 21, can form a gap 23.This gap can make the adhesive drying in said gap area, thus the performance of infringement adhesive.This danger is big especially as the cover layer with central wound pad for the cover layer with three-dimensional surface profile.
An advantage of the invention is not have the danger that this gap takes place, particularly when line of weakness deeply terminate in less than the limit of protective layer on and to press close to the protective layer 4 of viscous layer 3 surperficial when intact.Line of weakness also can be made of many apertures sometimes, at this moment just to some local lesion of viscosity of adhesive in the aperture, can not make the viscosity in the continuum all poor.
Once found; when protective layer is that the polypropylene film of 100 μ m constitutes by thickness; and strip material is when also being the polypropylene film of 100 μ m for thickness, can be that both make closely and the line of weakness of opening easily as the loudspeaker combined effect of the ultrasound unit of 20kHZ DCP 2200 types of anvil face and U.S. Dukarle company on the dome limit of the semi-circular cross-section of 0.5mm with having radius.
Described device can be produced width from the product blank coiled material 2 of walking about by structure like this and be equivalent to half product of coiled material 2 width.If wish that product blank coiled material 2 is divided into width also to be easy to accomplish than above-mentioned also little product, as long as the required strip material 6 of cutting apart number is fixed on the protective layer coiled material.With regard to this respect speech, must make the number on the dome limit 9 of aiming at ultrasonic horn 10 and position certainly and adapt at the product number that transversely will be partitioned into of product blank coiled material.Install 1 change with respect to the product size change for convenience, ultrasound unit can be supported like this with the storage tep reel 7 that is loaded with strip material can move them by some suitable mechanism along pressure roller 8.All will change pressure roller 8 for fear of resetting each time when arranging, pressure roller 8 can be provided with a plurality of domes limit 9 along its length, makes its position with corresponding with the various width of all products of this method production.This sampling device 1 just can promptly be adjusted, as long as ultra-sonic welded unit and storage belt wheel are moved laterally on the position on the dome limit that will be used to facing to those.Nature, facing to all configurable ultrasound unit in each dome limit, so just needn't mobile ultrasound unit, as long as start those relevant ultrasound unit.
， Pinch hands band join protection layer 4 is installed on the product blank coiled material of walking about and is fixed Zhong an illustrated embodiment of method.But also can before said protective layer 4 is installed, make a kind of protective layer of Bao Kuo Pinch hands suitably, for example on protective layer, make with the moving direction of protective layer and become Heng Xiang De Pinch hands band with the method for intermittently operated.In this process, line of weakness is incomplete penetration certainly.
In the embodiment shown, ultra-sonic welded is used to makes seam, and makes line of weakness in seam central authorities in same operation.Also available hot weld method of perhaps this binding or gluing method are finished, and line of weakness can wait with traditional method such as punching and makes.Should be known in that the binding of strip material and the generation of line of weakness can carry out in the different stages.When making when sticking with glue, seam is preferably in just makes after line of weakness produces, and at this moment protective layer and strip material can be with making by heat weldable material, and all can use as materials of peelable material now.
It is that protective layer material and strip material only need be stored a kind of single width and got final product that described method also has an advantage, is adjusting the storage and the carrying that can make things convenient for these materials when production line is made new product greatly like this.
Though this method just describes with regard to making the product with uniform thickness; this method is not limited to this manufacturing; have the product of three-dimensional surface profile, as have the wound pad that is arranged in central authorities and the also available aforesaid way of wound cover layer that carried and surround by thin material provides Bao Kuo Pinch the protective layer of hands.This method is mainly used to make the wound cover layer, but should know, all products that comprise that viscous layer needs protection all can be according to the protective layer that the invention provides Dai You Pinch hands.
Described embodiment certainly is modified within the scope of the invention.For example, adhesive can be a SGA, and plastics such as polyethylene beyond the available polypropylene are used as peel-able film.Therefore the present invention only should be limited by appended patent claims.
