Abstract

The invention relates to a method for manufacturing a 12-strand mooring rope. The method comprises the following steps of A, putting three rope yarns onto a yarn twisting machine to perform first twist to form first-twisted rope yarns; B, putting the three first-twisted rope yarns onto the yarn twisting machine with the same tension to perform second twist to form one rope strand; C, performing 6+1 strand operation through a strand splitting plate of a stranding machine, taking one strand from the center, taking six strands from a first layer outward from the center, taking thirteen strands from a second layer outward from the center, and then performing stranding, wherein the lay length in each layer is set to be 177mm, the die hole diameter of a 6+1<th> layer is 5.7m, and the die hole diameter of the second layer is 9.3m; D, knitting twelve rope strands obtained in the C step through a knitting machine to form the mooring rope. The method has the advantages that the manufactured mooring rope is good in wear-resisting property, the utilization rate of fibers is high, and the like.

Description

A kind of 12 bursts of hawser manufacture methods

Technical field

The present invention relates to a kind of method that 12 strands of hawsers of rope make.

Background technology

The sth. made by twisting stock that hawser makes completes on strander, and the method that existing 12 strands of hawsers make is generally relatively more multiple Miscellaneous, the twist of rope, line density, lay pitch etc. do not reach requirement, in the past the first twist and then hawser anti-wear performance made compares Difference, the utilization rate of fiber is low, and in manufacturing process, the tension force of first twist and retwist is uneven, and strength can be caused to decline.

Content of the invention

The invention aims to overcoming the shortcomings of above, provide inserting mode simple, and grafting hawser out Connect reliable.

The purpose of the present invention is achieved through the following technical solutions：A kind of 12 bursts of hawser manufacture methods are it is characterised in that wrap Include following steps：

A, first take 3 rope yarns that first twist carried out on yarn-twisting machine, form the rope yarn after first twist；

B, take the rope yarn after 3 stock-traders' know-how first twists to carry out retwist on the yarn-twisting machine of equal tension again, form one rope strand；

C, elder generation carry out 6+1 stock operation on stranding machine share split disk, and center takes 1 strand, and the outside ground floor in center takes 6 strands, then The outside second layer in center takes 13 strands again, then carries out stranding, every layer of setting lay pitch 177mm, the nib footpath 5.7mm of 6+1 layer, and second The nib footpath 9.3mm of layer；

D, 12 strand stocks in step C are taken to carry out being knitted to form hawser on braider.

Forming the rope twist per unit after first twist described in step A is 40.8 T/m, and line density is 0.80 ktex.

The twist forming one rope strand described in step B is 28.0 T/m, and line density is 2.43 ktex.

The lay pitch of hawser described in step C is 336mm, and line density is 602 ktex.

The present invention has advantages below：The method that hawser makes is generally straightforward, the twist of rope, line density, the lay pitch Reach requirement, the even tension of first twist and retwist in manufacturing process, do not result in strength and decline, and then the hawser made is resistance to Mill performance is good, and the utilization rate of fiber is high.

Specific embodiment：

In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, should Embodiment is only used for explaining the present invention, does not constitute limiting the scope of the present invention.

The present invention 12 bursts of hawser manufacture methods of one kind are it is characterised in that comprise the following steps：

The method that hawser makes is generally straightforward, and the twist of rope, line density, the lay pitch reach requirement, so produce The hawser wearability come is good, the even tension of first twist and retwist in manufacturing process, does not result in strength and declines, and then makes Hawser anti-wear performance good, the utilization rate of fiber is high.

Claims

1. a kind of 12 bursts of hawser manufacture methods are it is characterised in that comprise the following steps：

C, first 6+1 stock operation is carried out on stranding machine share split disk, center takes 1 strand, and the outside ground floor in center takes 6 strands, then again in The outside second layer of the heart takes 13 strands, then carries out stranding, every layer of setting lay pitch 177mm, the nib footpath 5.7mm of 6+1 layer, the second layer Nib footpath 9.3mm；

D, 12 strand stocks in step C are taken to carry out being knitted to form hawser on braider；After forming first twist described in step A Rope twist per unit be 40.8 T/m, line density be 0.80 ktex；The twist forming one rope strand described in step B is 28.0 T/ M, line density is 2.43 ktex；The lay pitch of hawser described in step C is 336mm, and line density is 602 ktex.
