Which Automatic Sewing Machines Are Best For Climbing Popes And Rescue Ropes?

High-strength rope lacing technology is widely used in the reinforcement of climbing ropes, rescue ropes, and other safety ropes. The lacing lines are firm and uniform. Since the lacing structure at the ends of most ropes directly affects life safety, choosing a high-performance high-strength rope net sewing machine is of vital importance. It can significantly enhance the safety and durability of the rope lacing points.

 

Currently, in the production of woven and twisted synthetic ropes made of materials such as nylon, polypropylene, polyethylene, and polyester, heavy-duty wires and thick sewing threads are often required. These ropes are widely used in tree care, rock climbing and cave exploration, ship and marine operations, rescue, lifting, custom rope making, and woven rope making, among other fields.

 

Over the years, PACKSTAR has developed a series of fully computer-controlled rope sewing equipment, which can optimize the sewing process, make the sewing area smooth, and possess high strength and reliability. Compared to knots, the sewing eye rings on ropes and rope belts are more secure as they avoid the friction loss between the ropes and prevent the fiber structure from being damaged by bending.

 

Next, we recommend to you our net rope sewing machines that meets your rope production requirements.

 

1 Diameter of ropes

The diameter of your ropes will affect not only the minimum breaking strength, but also abrasion resistance, handling characteristics, weight. In production of normal climbing ropes and other safety ropes, we recommend below sewing capacity:

GN20-4NT:2-14mm

GK81500CZ: 6-20mm

Usually climbing rope manufacturers need to join two ropes of different thickness, so you need to be clear the minimum and maximum diameters of your ropes.

 

2.Speed of sewing machine

Sewing speed biggest concern for customers buying their sewing equipment, so it is better to choose a highest speed bar-tacking sewing machine that can sew the thickness of ropes.
GN20-4NT: 1400SPM

Gk81500CZ: 1500SPM

3.Rope Linear density

In view of same rope thickness, the linear density has great effect on stiffness of the climbing ropes. The three most common safety rope materials are nylon, polyester and polypropylene. For some extra rigidity & cut resistance synthetic fiber ropes (tenacity is over 1000 (g/denier), you need much heavier bar tacking machine or stronger needle penetration force.
So if you are to stitch extra stiff ropes for manufacturing military ropes, marine ropes, fire rescue ropes and other industrial ropes, it is better to send some rope material for testing, before order!

Why does PACKSTAR require samples from the customer when setting up an automatic rope sewing machine?

When writing climbing and security rope specifications, you should not neglect specifying the proper number of stitches per inch that should be used in your ropes and cordage. Why?

Because the number of stitches per inch can have a direct influence on the seam strength and stitch appearance.

Obviously, the seam strength is dependent on a number of factors including:

(1) rope materials; (2) rope density and thickness; (3) thread strength/thread type and size; (4)stitch count/number of stitches per inch; (5)weakening material from piercing with needle (type and weight of the Fabric); (6)pattern of sewing; (7) stitch balance (thread tensioning).

 

Generally, the more stitches per inch, the greater the seam strength, but it takes longer time in production. Furthermore, there are rare cases where adding stitches per inch can actually damage the rope fibers so that the seam is weakened, however, this only happens on specific rope fibers that can be damaged by excessive needle penetrations.

 

If you are not sure about the stitch count, thread size, needle size and sewing pattern, you can send us:

1) All types of ropes and cordage you are manufacturing;
2) With specific strength of each type rope and cordage;
3) Different size of threads you are using (testing with same quality of thread)

We will:
1) sew ropes with different thread size, and check the breaking strength
2) We will work out your "Prototypes" & make it to your specifications.
3) We will help you design best sewing solution for your rope sewing production (Avoid wasting time, material and capacity).
