The specific embodiment
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the present invention in this illustrative examples of the present invention and explanation, but not as a limitation of the invention.
The cylinder hardness that present embodiment provides is for double-deck, and the left side of internal layer and the outer field left side link together by a parallel, and the right of internal layer and outer field the right link together by a parallel, and internal layer and outer field other positions are separate.
The method that weaves above-mentioned double-layered cylinder hardness is:
Adopt parallel and eight layers of warp tissue braiding, the warp tissue of each layer is through on the brown frame sheet that links to each other with inkle loom palm fibre frame, each warp tissue is worn a brown frame, eight warp tissues are arranged on the inkle loom by the brown frame quantity that suspender belt will use, each brown frame adopts a pattern chain sheet to make up and controls, a pattern chain sheet combination comprises eight pattern chain sheets, pattern chain sheet up-and-down movement is controlled the motion of brown frame, thereby the path of motion of control warp tissue, specifically: the combination of eight groups of pattern chain sheets is fixed on the pattern chain wheel of ribbon machine side by side according to the order of eight brown frames putting on the suspender belt material on the ribbon machine, every group of corresponding brown frame of pattern chain sheet, pattern chain wheel and pattern chain sheet also can and then rotate during the ribbon machine turns, the pattern chain sector-meeting produces high and low running orbit in rotating process, the palm fibre frame also can produce under the effect of pattern chain sheet and the same running orbit of pattern chain sheet, then the brown frame sheet that links to each other with brown frame also can follow brown frame to move, when bonded assembly warp tissue carries out up-and-down movement respectively with eight brown frames, because each self-operating height, low asynchronism(-nization), the warp tissue will form the face that interweaves on the ribbon machine, in the process of warp knitting, two pattern chain sheets of every motion parallel just interts diction, will form a face when parallel has interted one group of pattern chain sheet circulation time.
In the present embodiment, outer this face that interweaves of upper semi-circle of double-layered cylinder hardness is by two groups of pattern chain sheet combination control, the arrangement mode of these two groups of pattern chain sheet combinations is: seven high one low, four high one low three height, and in accompanying drawing 3, warp tissue 1 and warp tissue 5 are woven into this face of outer lower half circle;
Outer this face that interweaves of lower half circle is by two groups of pattern chain sheet combination control, and the arrangement mode of these two groups of pattern chain sheet combinations is: three low one high four low, seven low height, and in accompanying drawing 3, warp tissue 4 and warp tissue 8 are woven into this face of outer lower half circle;
This face that interweaves of internal layer upper semi-circle is by two groups of pattern chain sheet combination control, the arrangement mode of these two groups of pattern chain sheet combinations is: three low one high and one low three height, three low one high and one low height, in accompanying drawing 3, warp tissue 2 and warp tissue 3 are woven into this face of internal layer upper semi-circle;
This face that interweaves of internal layer lower half circle is by two groups of pattern chain sheet combination control, the arrangement mode of these two groups of pattern chain sheet combinations is: one low three high one a low one high and one low height, the low height of a low one high and one low Senior Three, in accompanying drawing 3, warp tissue 6 and warp tissue 7 are woven into this face of internal layer upper semi-circle.
Because these eight groups of pattern chain sheets are to move simultaneously on the ribbon machine, the time that forms these four faces also can be because of the difference of pattern chain sheet high and low position difference, under the interting of parallel, be made into and have the double-ply cylinder hardness.
Receive the limit and in the process of braiding, carry out simultaneously, after parallel passes warp from left to right, receive the limit in the formation of the left side of warp with lock seaming; A serging device is arranged on the ribbon machine, the line of the usefulness of will lockstitching a border is through on this serging device, serging device is debugged the position of matching with ribbon machine crochet hook, when parallel moves to crochet hook position on the ribbon machine from left to right, crochet hook can hook parallel, and simultaneously serging device can be sent to hook in the crochet hook opening and forms lock seaming being through line on the device.
