Abstract

To provide a protective member having stable and good capacity and not generating trouble at the time of protecting work, in a protective member having a four-layered laminated sheet structure, by allowing a support to approach a fluoroplastic layer and making the peel strength thereof larger than that of a support approaching a hot-melt resin layer. A protective member is composed of a four-layered structure of support (a)/fluoroplastic layer/hot-melt resin layer/support (b). The support (a) has a release layer on the side providing the flouoroplastic layer and the support (b) has a release layer on the side providing the hot-melt resin layer and the peel strength of the support (a) is made larger than that of the support (b). When a member to be protected is protected by the protective member thus constituted, at first, the support (b) is released from the protective member but the balance of releasability is taken so as to prevent the release of the support (a) on the opposite side and, after the protective member from which the support (b) is released is bonded to the surface of the member to be protected, the support (a) can be smoothly released.

Description

Straight-bar machines

The present invention relates to straight-bar machines, particularly be related to and use fine-count yarn to carry out that densification weaves and knitting needle spacing following of the situation in addition improved straight-bar machines that has problems that narrows down.

For use fine-count yarn carry out fine-count yarn that fine and close braiding narrows down the knitting needle spacing with straight-bar machines on, the various key elements during braiding have a significant impact the crudy of knitted fabric.For example, swing, the tension change of yarn and the teeter of knitting needle etc. that are contained in the main triangle of balladeur train the inside are the bad main causes of coil.

The problem that the problem that relevant knitting needle needle latch and sinker collide in the problem that exists with straight-bar machines for fine-count yarn and the axial region of knitting needle come off from the broach shape tongue piece of flat spring, the applicant has developed in the new disclosed technology in No. 3010484 communique of case of Japan's practicality.

, because fine-count yarn is thin with yarn not only used on the straight-bar machines, and the knitting needle spacing is narrow, thereby easily produces broken yarn during braiding, and the skid resistance of balladeur train increases in addition; In order to prevent broken yarn and to reduce skid resistance, must increase the angle of main triangle as far as possible, and make knitting needle in the enough distances of braiding time shift action spot by a small amount of the moving of balladeur train.That is to say, though the lateral margin sliding-contact of heel of knitting needle pin and main triangle and mobile is vertically only moved braiding required separation distance, the angle of the necessary main triangle lateral margin of corresponding increase in order to make knitting needle when the knitting needle spacing narrows down.

But in this case, owing to exist big deviation aspect the loading of knitting needle pin heel group when the triangle group by the balladeur train the inside is drawn by the braiding passage or when making balladeur train with the high speed braiding of high speed slippage, sliding-contact is made and is surpassed necessary moving because of inertia leaves this end to the heel of the knitting needle pin of main triangle lateral margin end, causes that coil is inhomogeneous and causes coil bad.

In addition, aspect the relation of balladeur train and needle-bar, in the guide pipe that makes the C tee section that the is located at balladeur train the inside structure chimeric sliding freely with being located at guide rod on the needle-bar, if between these guide rods and guide pipe, rock, especially promptly can rock that to produce coil bad on straight-bar machines because of this at above-mentioned fine-count yarn.

The present invention in view of fine-count yarn with the problems referred to above of straight-bar machines, its objective is that providing a kind of can prevent simply that leaving main triangle because of the heel of knitting needle pin makes and surpass necessary moving to produce coil bad and produce the bad straight-bar machines of coil because of rocking of guide rod and guide pipe.

Straight-bar machines of the present invention for solve above-mentioned before a kind of reason coil of producing bad, a kind of and main triangle interlock is installed on balladeur train, and can be left main triangle to the knitting needle pin heel of main triangle lateral margin guiding and make and surpass the mobile auxiliary triangle of stipulating that limits.Prevent that by auxiliary triangle the heel of knitting needle pin from leaving main triangle because of inertia and work surpasses necessary moving.Auxiliary triangle is by being located at coil on balladeur train interlock and remain certain relation therewith when regulating dial and making main triangle action.

In addition, bad for solving above-mentioned back a kind of reason generation coil, on guide pipe, be provided with internal thread part, set screw and this internal thread part that front end and guide rod are joined screw togather, and regulate rocking of guide rod and guide pipe by this set screw again.

Below in conjunction with the description of drawings embodiments of the invention.

The accompanying drawing simple declaration:

Figure 1 shows that the back side of the balladeur train of straight-bar machines of the present invention.

Fig. 2 is the vertical view of the secondary triangle of main triangle and both sides thereof.

Fig. 3 is the same front view.

Fig. 4 is the rearview of the configuration relation of secondary triangle of main triangle of expression and both sides and auxiliary triangle.

Fig. 5 is from the being seen stereogram in the same oblique below.

Fig. 6 is the vertical view of auxiliary triangle.

Figure 1 shows that the back side of balladeur train 1.Balladeur train 1 is entrenched on the guide rod 3 that is located on the needle-bar (not shown) guide pipe 2 of the C tee section of the posterior lateral margin portion that is fixed on its back side sliding freely, and can be by manually making it along the left and right sides slippage on needle-bar of this guide rod 3.The both ends of guide pipe 2 have hole 4 respectively, simultaneously with these hole 4 consistent nuts 5 that are fixed with.And, the front end of this set screw 6 is joined by hole 4 and guide rod 3 with the internal screw-thread screw of set screw 6 with each nut 5, can regulate rocking of guide rod 3 and guide pipe 2.

The back side of balladeur train 1 except that about the main triangle 7, various triangles are all the same with prior art to be the left-right symmetry configuration.Be contained in not shown coil above the balladeur train 1 when regulating dial and rotating, main triangle 7 moves simultaneously about can making as prior art by not shown mechanism.

As shown in Figures 2 and 3, first auxiliary triangle 8 and second auxiliary triangle 9 can be journaled into the both ends of each main triangle 7 with horizontally rotating by

triangle axle

10,11 separately.Main triangle 7 forms enough angles for guide pipe 2 parallel straight lines and is installed on the balladeur train 1.Balladeur train 1 one slides, and then knitting needle pin heel 12a is rearward mobile with knitting needle 12 with the lateral margin 7a sliding-contact of the main triangle 7 of inclination.The route of knitting needle pin heel 12a is shown in arrow among Fig. 1 under " plain weave " situation.

Auxiliary triangle 13 is maintained on each main triangle 7.Shown in Fig. 4,5,6, auxiliary triangle 13 is the vertical triangular part 13b of the sagging formation of front end (rear end) bending integratedly of the sweeping horizontal fixed 13a of portion when overlooking, and both ends, the left and right sides 13c of this triangular part 13b is done bending slightly to make it tilted rearward.Auxiliary triangle 13 is by making

hole

14,15 and

triangle axle

10,11 chimeric being fixed on the main triangle 7 that are located on its fixed part 13a, and with main triangle 7 one interlocks.The triangular part 13b that is fixed on the auxiliary triangle 13 on the main triangle 7 like this and the rearward end 7b of the lateral margin 7a of main triangle 7 between can only form and allow the laterally gap 16 by required width (the front and back width than knitting needle pin heel 12a is big slightly) of knitting needle pin heel 12a.

Therefore, after moving to the rearward end 7b of this lateral margin 7a with the lateral margin 7a sliding-contact of main triangle 7 and the knitting needle pin heel 12a that rearward moves in case enter gap 16, the rearward restriction of moving the triangular part 13b that promptly is subjected to auxiliary triangle 13 of this knitting needle pin heel 12a, and the front one side sliding-contact one side of this triangular part 13b is horizontal by gap 16.Knitting needle pin heel 12a that is to say, even because the angle of the lateral margin 7b of main triangle 7 causes the inertia that produces with its sliding-contact to increase greatly, also can prevent to leave main triangle 7 and rearward make above necessary moving.

Adopt the present invention, make mobile restriction that surpasses regulation owing to come that by auxiliary triangle main triangle is left in knitting needle pin heel with main triangle interlock, though since the angle of the lateral margin of main triangle to make its inertia increase with the sliding-contact generation also can not produce coil greatly bad.

In addition, owing to can adjust rocking of guide rod and guide pipe, can prevent that to rock the coil that produces bad because of this by set screw.
