Description
Technical field
The present invention relates to invagination (tuck-in) method and device thereof that a kind of shuttleless loom uses.
Background technology
, as one of selvage weave with shuttleless loom woven fabric, there is in a kind of opening of the parallel end of wefting insertion being gone back to follow-up parallel institute wefting insertion, fold into the invagination selvedge in fabric together with follow-up parallel.
As the device that forms this invagination selvedge, such air injection type folding device shown in known a kind of patent documentation 1.In addition, the action of the parallel end of wefting insertion being gone back in the opening of follow-up parallel institute wefting insertion calls invagination, and folding device is also referred to as the air pleating device.
The folding device of air injection type, have two sides that are configured in through alignment, respectively to the turn back invagination nozzle of use of parallel.And, by utilizing from the jet-stream wind of this invagination nozzle ejection, the parallel both ends of wefting insertion are gone back in opening and are folded into.
, about having the action with the air injection type folding device of patent documentation 1 same general configuration, with reference to Fig. 5,6, do summary description.In addition, Fig. 5 represents the folding device to the line side, but also configures same folding device for the line opposition side.Utilize the parallel 42 of Weft insertion nozzle 33 wefting insertion at shedding 30, by the front of not shown reed and then to fell 31, beat up.At this moment, parallel enter for line side end 42a to fold into a slit 52 of 51, cut off by cutting knife 32 and the parallel in Weft insertion nozzle 33, simultaneously, the injection stream of being controlled nozzle 53 by the parallel end is blown into the parallel end and controls in hole 54, and is tethered in the parallel end and controls in hole 54.
When reed retreats, in case controlling nozzle 53, the parallel end stops the air injection, and parallel discharges nozzle 55 and just starts the air injection, and the injection stream of utilizing parallel to discharge nozzle 55 is controlled hole 54 with parallel end 42a from the parallel end and is drawn, and blows out in slit 52.Then, fold into nozzle 44 and start the air injection, parallel end 42a utilizes the injection stream that folds into nozzle 44 and is blown in shedding 30, turns back into round.And, the parallel end 42a after turning back be beaten together with follow-up parallel and fold in fabric 41 together with follow-up parallel.
In general fabric, sealing is good in order to form, the good invagination selvedge of outward appearance, the parallel end 42a that preferably from the position of wefting insertion, directly turns back and folded into, and the state very little with the round of fold back portion is beaten.Therefore, in air injection type folding device in the past, configuring and folding into nozzles 44 near fell 31, the parallel end 42a that turns back forms little round as far as possible, and, configuration selvedge valve nozzles 56, be blown into to shedding 30 inboards the parallel end 42a that has folded into the application of force near fell (initial point of shedding), can prevent that parallel end 42a is lax.
Yet, for by the woven fabric of shuttleless loom, have to comprise that two kinds that weft density differs widely are weaved fabrics partly the fabric (hereinafter referred to as " rubber strengthens use fabric ") of strengthening use as rubber.Here, so-called rubber is strengthened using fabric, refers to the fabric that uses as the core that elastomeric material is strengthened, and is to comprise these the two kinds fabrics of weaving part: the cord fabric part that weft density is very thick; And with respect to the cord fabric part, make the close plain weave part of weft density.
In addition, cord fabric is partly to become rubber to strengthen using the part of fabric body, and plain weave is partly to form the part of specific length before the braiding of cord fabric part starts and after the braiding end on warp direction, is to prevent that the thick cord fabric of weft density from partly crumbling, keeping rubber to strengthen the part of using with the fabric shape of fabric.
Strengthen using an example of fabric as rubber, can enumerate the tire cord fabric.So-called tire cord fabric, refer to strengthen using fabric, body piles to become the skeleton of rubber tyre for the manufacture of the rubber of body piles, and the cord fabric of body piles by elastomeric material being coated on the tire cord fabric made on partly.
In the close plain weave part of weft density, use the viewpoint of the fabric shape of fabric from keeping rubber to strengthen, identical with general fabrics, preferably directly turn back and become good closed state from insertion position in the parallel end after turning back.
On the other hand, in the thick cord fabric part of weft density, strengthen using the viewpoint of fabric quality aspect from rubber, the parallel end after turning back is as shown in Figure 2, best and parallel interval (density) as one man forms large and mild radian, becomes along the state of the follow-up parallel that beats up.
Yet, in the folding device of aforementioned conventional art, carry out injection action owing to folding into the certain position of nozzle on warp direction, when weave rubber strengthen with fabric such exist weft density close weave part and weft density thick weave partly fabric the time, determine to fold into the position of nozzle if contrast a side the part of weaving, weaving partly of the opposing party, can not form good invagination selvedge.
Especially, when weaving the very thick cord fabric part of weft density, if carry out the plain weave part identical invagination close with weft density, if namely use the invagination nozzle close to the position of fell to fold into, follow-up parallel can turn back by the opposition side of sending on warp direction than the position of beating up sometimes, and the parallel end that has folded into can not be beaten and become the state (with reference to Fig. 7) that folds in fabric.This state, strengthen just becoming qualitative shortcoming with fabric for rubber such as tire cord fabrics.
According to above explanation, the preferable states of the parallel end that has folded in plain weave part and cord fabric part on the contrary, is to realize this opposite state with the folding device of above-mentioned conventional art.
In addition, in the air injection type folding device identical with above-mentioned conventional art, have at warp direction and establish a plurality of invagination nozzles, relying on the interlock of a plurality of invagination nozzles the parallel end to be folded into the folding device of (turning back).But in the situation that use this folding device, its formation is respectively to fold into nozzle just to spray whenever folding into action, relies on the interlock that all folds into nozzle to realize once folding into, and opposite invagination state as described above can not be realized simultaneously.
