Due to the continuous and robust nature of fiberglass, it is being utilized in everyday life.

fiberglass ud tape

The primary applications include construction materials, sports equipment, water supply accessories, agricultural products, etc.

With the advancement of society, people’s standard of living has vastly improved.

In the business sector’s CFRT industry, fiberglass is a prevalent material.

There are various forms of fiberglass rolls, with unidirectional and woven being the most prevalent.

Our fiberglass roll slitting machine is suitable for cutting fiberglass unidirectional tape swiftly and efficiently.

A machine for slitting fiberglass rolls can be used to cut reinforced composites, such as PEEK carbon fiber unidirectional tape, carbon fiber prepreg tape, and some thick paper.

We offer slitting machines ranging in width from 900 to 1600 millimeters for turning large tape into narrow-width tiny rolls.

Let’s take the JT-SLT-900E slitting machine model from the chapter below.

  1. Unwinding stand
  2. Slitting blade
  3. Rewinding and automatic unloading system

The aforementioned is the typical functioning principle of every slitting machine.

To initiate a roll slitting machine, the moving direction and tracking must be configured so that the operator can manage the slitting process with ease, the movement direction is often either front- or rear-facing.

Additionally, the tracking should be flexible to accommodate various widths of CFRT UD tapes.

Before choosing a machine, it is important to consider the thickness of the material and confirm that the slitting pattern will meet your specifications.


Fiberglass is an application of thermoplastic unidirectional Tape (UD tape) comprised of PA/PP/Nylon yarn and resin granules.

thermoplastic resin

The primary benefits of using fiberglass are its high strength, toughness without brittleness, resistance to high temperatures, low weight, strong thermal conductivity, and resistance to heat.

shatless unwinder stand

This type of product is predominantly utilized in electrical insulating circuit boards, chemical industrial equipment, and other applications.

Typically, the jumbo roll is so hefty that it cannot be moved by hand. We utilize the hydraulic lifting method for JT-SLT-900E to solve this problem and boost efficiency.

The roller is constructed from high-quality alloy steel, has a long service life, and is ideal for the production lines of various jumbo rolls.

We provide you with two options: a shaftless unwinder and a 6-inch air-expanding shaft.

Slitting blade

As is common knowledge, fiberglass is a highly dense thermoplastic.

For the JT-SLT-900E to perform properly with ud tape, we employ HSS (high-speed steel) instead of paper blade material.

The fiberglass UD tape slitting edge is sharp but has a somewhat rounded form. Paper cardboard is difficult to cut, yet it is simple to cut into strips.

In our equipment, paperboard and fiberglass should not be combined. The explanation is that the smooth surface of paper cardboard will make the slitting edge rough, whereas the fine and transparent surface of fiberglass will make the slitting edge smooth.

slitting blade

While the edge of paper cardboard will be sharp, the edge of fiberglass board will be less so.

The physical detection tool can differentiate between the two. Therefore, the roll shaft slitting machine must be fitted with a suitable roll holder or roller to ensure normal operation and prevent material damage during the cutting process.

HSS is a high-speed steel that, as a result of tempering at a high temperature, has excellent wear resistance and cold-break resistance.

It has a lengthy service life and is impervious to material impact and friction.

Rewinding section:

The rewinding section is the most significant section of a slitter machine, but our distinctive rewinding type not only maintains the quality of the final product and increases production efficiency, but it is also an important characteristic of our machine.

UD Tape Rewinding

When utilizing 900E, we typically provide our clients with a mold temperature machine, primarily for use in conjunction with our water-cooled differential friction shaft.

The shaft may apply uniform stress to the glass fiber, ensuring that the surface of the rolled product is smooth and the tension is constant.

However, the common differential friction shaft has a fatal flaw in that friction and heat cause the inner cowhide strip to deteriorate.

The mold temperature machine continually offers water cooling when the differential friction shaft is winding the material.

On the take-up reel, a circulating cooling system is therefore installed. In this manner, the cowhide strip is protected from long-term heat exposure, extending its service life.

This friction shaft has been patented by our company.

System for automatic unloading

The maximum rewinding diameter of 900E can exceed 800mm, despite the fact that the final result is not particularly enormous. We propose an automated unloading system for the safety of manufacturing.

We will write the automatic unloading function into the PLC program.

The automatic unloading arm pulls the glass fiber forward when the differential friction shaft rotates in the opposite direction. By clicking unloading on the touch screen, production personnel may automate activities.

What is CFRTP?

Carbon fiber reinforced thermoplastic (CFRTP) is a composite material made of pre-impregnated carbon fiber and thermoplastic resin (like PP, PE, PA, PA6, PA66, PPS) PEEK)by Hot Melt Prepreg Methods.

The plastic polymer will be hot melted by a twin co-extruding plastic extruder in high temperatures from 260 degrees to 450egree, then the resin will be immersed in an M-shape mould where be prepared with the carbon fiber or glass fiber under the help of the high pressure and high temperatures.

Then after calendering rollers cooling and calendering, the Unidirectional tapes are formed, then rewind into rolls.

In China, the CFRTP UD tape standard width is 650mm, and sometimes 1300mm wide is required, and the thermoplastic carbon tape width is mainly 150mm to 300mm.

The tapes thickness from 0.2mm to 0.3mm in weight from 170gsm to 300gsm.

What are Thermoset Epoxy Carbon Tapes?

Thermoset epoxy carbon tapes are high-quality carbon fiber prepreg tapes that are used to prepreg carbon fiber is woven fabrics or carbon fiber that has been soaked in epoxy resins and then dried to create expoxy carbon tapes, which are then used to make carbon fiber composites.

Polyester and epoxy resin form the basis of thermoset epoxy carbon tapes, with glass fibers or carbon fibers added in varying proportions.

It can be employed in a variety of fields, including aircraft, wind energy generating, and sports equipment.

Epoxy is a rigid thermosetting plastic, which means it becomes permanently hard and non-malleable after high pressure, high temperature curing in the tank.

The term “thermoplastic molding” refers to a procedure in which the curing reaction is triggered by heat rather than a chemical reaction using a catalyst.

Thermoset epoxy is a very strong and resistant substance with great temperature resistance and abrasion resistance.

What are Thermoplastic UD tapes?

Thermoplastic UD tapes have a carbon fiber reinforcing and are a high-performance elastomeric material.

The UD material is made by molding a polymer or other resin around a continuous reinforcing textile filament, such as carbon fiber or woven fiber, that is inserted in the resin matrix during the high pressure, high-temperature pre-impregnation process.

Unidirectional is shortened as UD. This means that one side of the tape is smooth and flat, while the other side has a texture comparable to that of woven materials such as cotton or wool.

The flat side is utilized to adhere to substrates, while the textured side is used to adhere to the surface of the substance being bonded.

UD tapes can be used to make robust and long-lasting connections between two materials or surfaces.

They’re also commonly utilized as an adhesive backing on carbon fiber prepregs before they’re cut into panels or strips for usage in items like aviation parts or automobiles.
