A SELECTION OF OUR MACHINERY AND MACHINE COMPONENTS

We have a wide range of products. Below you will find a brief overview of the laminators, winding machines, and the machine parts that we supply. A large part of our work consists of custom-made solutions, we therefore can’t show you everything here. Do you want to know what we can do for you? Call us on +31 (0)35 5261489 or send us a mail

 

PNEUMATIC WINDING SHAFTS

It is difficult to give a standard overview. Pneumatic winding shafts are produced in many types, based on a number of basic principles. The diameters vary from 25mm up to 600mm and you can choose from square, triangular or round journals. Besides the standard double bearing shafts, there are also cantilevered versions available. This can make it a lot easier to work with the rolls.

If a pneumatic winding shaft is not suitable due to the roll weight or machine speed, then a pneumo-mechanical winding shaft can be used instead.

MECHANICAL CLAMPING CHUCKS

For both practical and ergonomic reasons it is becoming more common for manufacturers to choose pneumo-mechanical clamping chucks.

In other words: shaftless winding. In addition to the basic elements, we can also adapt the clamping chucks to your specific wishes.

SAFETY CHUCKS

The default program contains three different apertures for holding the spindle: A1 (image 1), A2 (image 2), A3 (image 3). The dimensions are shown in the table below. The tolerance field of type A2 and A3 is within H7. The opening of type of A1 lies within 0/+1 mm.

Besides the foot-mounted chucks shown below, all types are also available as flange versions. Moreover there are types available which can guide the roll. Contact us for the possibilities concerning handwheel locking, controllers, conical studs, high-speed safety clamps and feet for web guidance.

WEB TENSION CONTROL

Along with the brake system, maintaining a constant web tension is very important. A constant web tension during winding is essential for a good final result. The force measuring sensors register any mechanical distortion that is caused by the web tension.

This input is converted into an electrical signal. Thanks to the combination of force measuring sensors, web control and brakes or clutches, we can guarantee an extremely stable production process. We don’t just sell products, we can also install them on your production line and give you all the advice you might need.

CLUTCHES AND BRAKES

We have a very wide range of clutches and brakes. The type that you’ll need is dependent on the particular situation. Not only do we offer a wide range of wheels, but we can also adapt the internal mechanism to your particular needs. Contact us  if you have any specific requests. We will gladly discuss the best option for you.

SPREADER ROLLERS OR BANANA ROLLERS

Spreader rollers are used in several sectors, such as the foil, textile and paper industries. Advantages:

  • The special bearing construction ensures that the roll runs very easily. So easily in fact, that the material turns the roller.
  • The use of steel also makes the roller suitable for higher speeds, such as those used in the paper industry.
  • Spreader rollers with adjustable bow heights are available for larger static loads.
  • They can also be equipped with an oil chamber system, for use in damp surroundings.
  • The use of high quality materials means that bow rollers are easily repaired.

Standard Spreader rollers are supplied with a large range of various rubber coatings. Special surface profiles can also be supplied.

WEB GUIDANCE

Sensors are available in the following types: LED, compensated ultrasonic, high temperature, dangerous environment and line detection types.

Steering frames are available in the following types: positive displacement assemblies, PDG (4 rolls), Double Roll Steering Roll (DRSR), Single Roll Steering Roll (SRSR), heavy and light.

The systems are available in both analogue and digital versions, each with its own distinct advantages. Based on your specifications, we can build a system that is optimised for your particular situation. We also offer the option for a computer interface. This allows all guidance to be controlled from a single computer.
