As shown in Figure 6, the seam machine machine 4 of left and right sides selvedge is made up of with quilting machine 35 selvedge that passes on conveyer 34 and vertically arranged second conveyers 36 of first conveyer 28 and be placed in belt 8 both sides of conveyer 36 by high speed rotary.As shown in Figure 8, also be provided with the warpage guide member 32 that selvedge is directed to next door, sewing needle position with banded cloth 30 from banded cloth cylinder 31.Neck portion established woollen blanket cloth sheet 16 when being transported to this conveyer and being passed between the cylinder 34 by first conveyer 28, will be sent to the centre of conveyer 36 and cylinder 34, via receiving belt 7(Fig. 1) send second conveyer 36 to.

At the warpage guide member 32 shown in Fig. 8 and Fig. 9, have introduction part 66 that the front with selvedge Sewing machines 35 almost extends in parallel and go out the parts such as leading-out portion 67 parallel with the longitudinal edge of woollen blanket 10 from this introduction part quarter bend.Introduction part 66 almost is very smooth in the face of the end portion of banded cloth cylinder 31.It is very close to woollen blanket cloth sheet 16, and the while is bent upwards in the central authorities of length direction gradually, forms two double walls 68 at last, and guides banded cloth 30 to arrive the centre of two double walls and introduction part 66.The leading-out portion 67 that is connected with introduction part 66 as shown in Figure 9, is bent downwardly in the central authorities of length direction, and its two ends are the U oxbow, and the side part that makes woollen blanket cloth 10 is by banded cloth 30, and promptly vertical selvedge 98 encases.Selvedge is to extract out from banded cloth cylinder 31 along continuous straight runs with banded cloth 30, introduction part 66 by warpage guide member 32, in this introduction part along its length with banded cloth at leisure to invagination, then when leading-out portion 67 contacts with the fore-end of woollen blanket cloth 10, outside reflexed and encase the fore-end of woollen blanket cloth again is with two pin 37(Figure 10 of Sewing machines 35) selvedge 98 of encirclement is sewed on flat stitch.As shown in Figure 8, be provided with at the rear of Sewing machines 35 that install between roller 95,96, two rollers of sending woollen blanket cloth edge can free rotating cut-off knife 97.Make the speed of gyration of the roller 95,96 of sending woollen blanket cloth sheet 16 marginal portions identical with the work feed speed of Sewing machines 35, woollen blanket cloth marginal belt after selvedge 98 is sewed up so can not take place stay the situation at Sewing machines rear, woollen blanket cloth edge more can not take place dragged the situation of pulling by roller 95,96.

The needle plate 100(of Sewing machines 35 is shown in Figure 9) to compare with commonly using needle plate, its flat shape is different.(be edge woollen blanket cloth sew up back) forms three and rightly mainly send tooth cave 102 needle plate 100 at 101 rears, pin cave, is positioned at herein master and send tooth 103 with selvedge 98 position backward.Like this, the needle plate 100 of Sewing machines 35, since it only with main send tooth 103 after selvedge 98 is sewed up with the past post-tensioning of this selvedge, so the extension of woollen blanket cloth edge part becomes less, mainly sew up the back in selvedge 98 and constrain it, so the influence that 100 pairs of woollen blanket cloth of needle plate edge part is extended is just very little with pressing plate (not shown).This pressing plate is less compared with the vertical degree of depth of the pressing plate of commonly using, and just part distance when laterally pressing in woollen blanket cloth edge is shortened.And needle plate 100 also is provided with square otch 106(Fig. 8 in the place ahead in pin cave 101), the front end of warpage guide member 32 is wanted to embed in the position of this otch.Like this, it is elongated with the distance of banded cloth to cover selvedge with warpage guide member 32 on the Sewing machines 35, when having covered, selvedge is sewn onto on the woollen blanket cloth sheet 16 with banded cloth 30, therefore needn't be for another example in the past like that making before selvedge sews up with banded cloth 30, send tooth that the direction of its past pin 37 is sent into two needle plate earlier.Needle plate 100 is equipped with main send tooth 103 and the differential tooth 105 that send elongated the sending of left end on the Sewing machines 35 in the tooth cave 104, but because selvedge is with the position of banded cloth 30 sending on the tooth cave 104 at left end not, so only there are woollen blanket cloth sheet 16 marginal portions to be subjected to the differential concentrated function influence that send tooth 105, when selvedge was sewed up, horizontal extension diminished.In addition, the main shaft of Sewing machines 35 (not shown) turns round once, main send tooth 103 and the differential tooth 105 that send to shake, this moment is differential send tooth 105 move forward and backward distance main send tooth 103 to move forward and backward distance big.The described difference that moves forward and backward distance is exactly the differential intensive quantity of sending tooth 103, and the fore-end of woollen blanket cloth sheet 16 is subjected to concentrate effect because of the differential tooth 105 that send, thus selvedge with banded cloth 30 when sewing up, horizontal extension is minimizing just.

Put second and pass on woollen blanket cloth sheet 16 on the conveyer 36 during, allow the end face and guided plate 107(Fig. 8 of woollen blanket cloth sheet by the operator near Sewing machines 35) contact, with the adjustment position.At Sewing machines 35 places, woollen blanket cloth sheet 16 front end positions are surrounded and selvedge 98 is sewed up with banded cloth 30, this banded cloth is selvedge cylinder 31 supplies by the Sewing machines right side.As shown in Figure 8, the vertical direction between roller 95,96 is equipped with 97, a woollen blanket cloth of the cut-off knife sheet 16 that can place by after finishing, just by cut-off knife 97 with selvedge 98 severings.At last as shown in Figure 1, woollen blanket cloth sheet 16 is sent to laterally once more, making it to pass on conveyer 36 by second is transferred to the 3rd and passes on the conveyer, this forwarding method with pass on conveyer by first and be sent to second to pass on the method for conveyer identical, being located at the 3rd, to pass on the structure of the selvedge Sewing machines 70 on the conveyer 38 identical with foregoing Sewing machines 35.It is parallel to make the throughput direction and the 3rd of the lower edge part of woollen blanket cloth sheet 16 pass on the direct of travel of conveyer toward horizontal passing on, and will cover this woollen blanket cloth sheet lower edge banded cloth of selvedge partly with Sewing machines 70 simultaneously, sews up with linear fashion.
