Abstract
The present invention is for making the method for the bag that flanging band rivel is arranged at short notice.Also can be used for rigid material.The flanging 1 of Bag Material 6 is needing to clamp two outer folding seamed edges 4,5 with the guiding seamed edge location that places the Bag Material both sides on the rivel high 10 corresponding distances from Bag Material opening 12 places, the folded degree of depth always equals the folded depth 11 of flanging.Each upset two outer folding seamed edges about 90 ° to a plane perpendicular to the Bag Material face, it is one trapezoidal that invagination seamed edge 3 is launched into.Trapezoidal fold plane after the invagination seamed edge doubling that launches, is pushed a pleat sheet 21 that folds 16,17 of sidewalls respect to one another, and the placket bag edge 15 Bag Material in it and the pleat district on vertical is connected.
Description
The invention relates to the method for making a kind of Sack with pleat made from leno cellular or fire hose belt pipe with flanging, fire hose belt pipe is made by woven or non-woven fleece.
Disclosed by patent documentation AT-B256601 in the method that folding rivel on the Bag Material of flanging is arranged, but a kind of in the document have the flat fire hose belt pipe Bag Material of flanging to be made by material that can encapsulate or sealing, its sidewall of alignment carrying that the part of sidewall is wound perpendicular to the Bag Material major axis at the sack place overturns 180 °, after this, the pleat sheet is sticked on the flanging place of opening, and the pleat sheet constitutes the prolongation of rivel.Then, will open part and turn back the origin-location again, simultaneously, the pleat sheet is folded.Last procedure is the sack of band rivel to be sealed, for example stitching.
For making rivel longer, before opening or with Bag Material, open certain degree of depth from vertical cutting inwards that sack is parallel to Bag Material, perhaps cut out the bag sample of lengthening at Bag Material flanging place.First measure requires an additional separately manufacturing procedure, i.e. a kind of blank material of regulation is opened or produced in cutting; Second measure causes out of use short.
Another shortcoming of known method is, the part of fire hose belt Bag Material is opened 180 °, and This move needs the long comparatively speaking time.Have high rigidity or intensity if make the material of pocket, folding 180 ° is difficult.Paste the pleat sheet and just require folding 180 ° of pleat sheet under deployed condition, this is folding to be at folding 180 ° for the first time, finishes after promptly opening.
The objective of the invention is to avoid these shortcomings and difficulty, its task is to create a kind of manufacture method of Sack with pleat, this method also can at first be finish rivel at short notice folding simply with the rigidity Bag Material time, might keep the of short duration cycle like this when producing in batches.Secondly, pleat length can also change, and does not need special bag method of cutting out, also can not cause short.
Task of the present invention is with the solution that combines of following feature:
A) fire hose belt pipe at least its part be to be used on the chemical property with the material extruding of the materials similar of fire hose belt pipe to film,
B) flanging always is folded into by the outer folding of an invagination seamed edge and two seamed edge,
C) Bag Material gets off by the cutting from the fire hose belt pipe of the length of bag,
D) be equivalent to be used on the high distance of required pleat the flanging location of the guiding seamed edge of Bag Material two sides with Bag Material at distance Bag Material openend, be about to its clamping, the guiding seamed edge is roughly parallel to a bag opening,
E) two outer folding seamed edges always with the guiding seamed edge clamp be equivalent to flanging a folding deeply, the two outer seamed edges that at every turn overturn about 90 ° to a plane, this plane is perpendicular to the Bag Material face, the invagination seamed edge is unfolded, form one trapezoidal,
F) subsequently with trapezoidal fold plane along the invagination seamed edge that launches to folding up,
G) pushing a pleat sheet that folds after the doubling between the sidewall respect to one another, and with its be positioned at the pleat district, be connected at the placket bag edge of Bag Material longitudinal extension,
H) will there be the bag opening of rivel to seal subsequently.
To fold seamed edge and creatively only upwards fold 90 ° at every turn, promptly upwards open 90 °, with respect to prior art, folding rivel operation has been divided into two folding processes of finishing simultaneously, the desired angular movement of this folding process only is half of prior art, like this, particularly when producing Sack with pleat in batches, only with short cycle time.Another advantage is that the pleat sheet has given earlier and having carried out, and has folded in the time of promptly on being placed in bag, no longer needs to fold after fixing.Produced advantage thus, particularly when pasting the pleat sheet, cemented the pleat sheet because no longer need as prior art requires, before folding pleat sheet, must wait.When pasting the pleat sheet, the pleat sheet that has folded is pushed, brought another advantage, promptly make glue be evenly distributed.
If make rivel have long especially pleat, the distance from unlimited sack to the location of Bag Material flanging is more preferably greater than the folded depth of twice flanging.
For the obstruction of the air that the time do not entered in pack, meet purpose in the part district's perforation of filming at least, preferably only in the perforation of flanging scope or only bore a hole in the rivel peripheral region.
If on the leno cellular length direction, in the scope on flanging expansion plane, do not push and film, then might not need bore a hole.
Bag by method of the present invention is made characterizes by making up following feature:
A) bag wherein has at least the part extruding to film by the leno cellular with flanging or have the woven of flanging or fire hose belt pipe that non-woven fleece is made is made,
B) at the folding rivel of an end of bag, rivel is symmetrical in the upper side of bag and the mid-plane between the downside, and has blind end that is substantially perpendicular to bag, and by the rivel opening that the Bag Material limit constitutes, this opening is equipped with a rivel sheet,
C) flanging is stopping from the high distance of blind end rivel, from the rivel opening part, toward each other and a bag face that encases rivel not only extend to folding seamed edge smoothly, and extend to the sack of sealing.
If the rivel height is greater than the twice of the folded depth of flanging, it is long that this rivel just has big rivel, and this is advantageous to loading certain article.
At least bag film the district partly the perforation be appropriate, according to first embodiment, only have in the flanging district perforation be favourable, according to the embodiment of second practicality, only in the rivel district, perforation is arranged.
The feature of another particularly advantageous embodiment is that the planar section that flanging launches on the bag length direction does not have class coating material.
Below, according to accompanying drawing the present invention being elaborated, Fig. 1 to Fig. 5 is a folding process of representing rivel with stereogram in detail.
Film with chemical property and the extruding of leno cellular materials similar in the outside of the leno cellular of one endless, leno cellular has the flanging 1 that is used in the common structural shape that unillustrated hemmer is folded on the figure, 2, they always have an invagination seamed edge 3 and two outer folding seamed edges 4,5.Cut out next section material 6 from these semi-finished product, it is long that its length 7 is equivalent to a bag, and seal 8 end at the bottom of will being called bag, for example with U-shaped band 9 involutions.
As shown in Figure 1, in a flanging scope of Bag Material 6, in the place that is equivalent to the distance of required rivel high 10 from Bag Material 6 openings 12, be used in the guiding seamed edge 13 of Bag Material 6 two sides, 14 clamp Bag Material, and rivel height required in the described embodiment of figure is greater than two of the folding of flanging 1,2 dark 11, guiding seamed edge 13,14 is parallel to opening 12 approximately.Open two outer folding seamed edges 4,5 then, invagination seamed edge 3 is unfolded simultaneously.Before about 90 ° of folding seamed edge 4,5 upset, by the support of an arbitrary shape, clamp two outer seamed edges with the guiding seamed edge earlier outside each, it is dark 11 that the folded degree of depth is equivalent to the folding of a flanging 1, will go up outer folding seamed edge 5 then and upwards curve, and rolls over seamed edge 4 outside down to curve downwards.
As shown in Figure 2, formed thus as among Fig. 2 with hacures represent trapezoidal, trapezoidal base be the bag opening edge 15.Trapezoidal extension plane be one with the bag plane promptly with the vertical plane 18 of undeformed sidewall 16,17.In order to make the folding seamed edge open or outwards open easily, the suction that the oriented direction that is separated is moved on the sidewall 16,17 chews 16 ', 17 '.
Subsequently with trapezoidal fold plane along the invagination seamed edge 3 that is unfolded again to folding up, promptly change 90 °, come back to bag place, a plane (see figure 3) until the crushed element of the sidewall 16,17 of bag.
Be ready to pleat sheet 21 at this moment, will be folding, and the pleat sheet 21 that has been coated with glue 20 at side 19 places pushes between upper side wall 16 and the lower wall 17 (Fig. 4), directly shift prolongation place that the folding rib 22 that makes the pleat sheet is positioned at the folding seamed edge 3 in trapezoidal centre onto, the limit wall 19 that scribbles glue 20 simultaneously covers present bag opening edge 15 along this part of Bag Material 6 longitudinal extensions, and sticks together with it.In order to push pleat sheet 21 easily, make 16,17 suitable the separating slightly of limit wall, for example chew 16 with inhaling once more ", 17 ".
Seal sack 12 at last, the U-shaped band 9 involution (see figure 5)s that available glue, sealing are lived or can be encased sack as said usefulness among the embodiment.
In described embodiment, push on the whole surface of bag and to film.For air can be released when packing, bag will have perforation, and the spacing of the thickness of pecker and perforation is selected according to the granularity of putting into article.Also can not bore a hole, if as not filming at flanging 1,2 place, just need not bore a hole in a part of zone of bag for example, it is excessive that its advantage is to avoid being coated with when filming.Leno cellular after the plastic sheeting of handy rolling launches as the material of bag.Also can be with the fire hose belt pipe of making by woven or non-woven fleece.
As shown in Figure 3, pleat long 23 depends on that pleat is high by 10, and promptly the distance from sack 12 to guiding seamed edge 13,14 is big more, and pleat stretches in the bag dark more.So just may see that to load sack relatively large, but can guarantee that still the sack that will load article seals.
