Joining

VIS conveyor and processing belts are either endlessly welded or mechanically joined, depending on the belt type and application conditions.

Below you can find our joining options:

Welded joints

single finger joining

It is particularly suitable for single-layer belts. In this process, the belt end is punched to form fingers, which are then stapled and welded together.

Benefits:

very flexible
for small pulley diameters
uniform belt thickness is guaranteed

multiple finger joining

This joining method is suitable for multi-layered and highly stressed belts. We split up the belt ends and punch fingers into the different layers, which are then stapled and welded together.

Benefits:

flexible and robust
for small pulley diameters
uniform belt thickness is guaranteed

stepped overlap joining

This joining method is characterised by gradually split belt layers in which the two ends are laid one on top of the other and welded or glued together.

Benefits:

robust and sturdy
cold bonding is possible
suitable for multi-layer belts

wedge joining

This type of joint is suitable for our tapes made of felt, rubber and multi-layer fabric. The ends are skived, ground off at an angle and laid one on top of the other and welded or glued together.

Benefits:

robust and sturdy
cold bonding is possible
suitable for multi-layer belts

Mechanical joints

Our mechanical joining solutions are suitable for applications that do neither permit the welding of the belt on site in the conveyor system nor the installation of an endless belt. They are offered in different lengths and thicknesses.

plastic spiral joint

Plastic spiral joints can be used for all belt types.

Benefits:

FDA compliant
robust and sturdy
allows for quick installation on the machine

anchor hook fasteners

Round or flat metal hooks are inserted into the ends of the belt, which can then be joined endlessly with a closing wire.

Areas of application:

belt thicknesses from 1.0 to 6.0mm
suitable for machine mounting

alligator fasteners

This method of joining is a mechanical joint with metal plates in the form of an alligator mouth, which are then joined endlessly with a closing wire.

Areas of application:

belt thicknesses from 1.5 to 6.4mm
suitable for machine mounting
