HOW IT WORKS

Based upon our TapeFormers Model C and D dimensions, allowing complete longitudinal paper tape wrapping during the manufacture of building wire.

The design consists of two TapeFormers fitted together with a ceramic guide to accommodate the copper ground wire insertion.

A version is available to form tape around just the ground wire and can include guides for the insulated cores.

Information required for manufacture

Insulated core diameter each core.
Ground wire diameter.
Tape width ground wire: Normally 0.875” (22mm) for all ground wire diameters.
Tape width assembly: We can recommend this please watch the video for more information.
Tape thickness

A TapeFormer exit is a fixed dimension and it is designed to be used with the cable diameter, tape width and tape thickness it has been manufactured for.

A jam will occur if a TapeFormer is used with a larger cable diameter, tape width and tape thickness than it was manufactured for, so this is not possible.

In some cases, it is possible to use a TapeFormer with a smaller cable diameter, tape width and tape thickness when used with a tape closing device e.g. a die. We cannot give guidance on how much smaller the cable and tape can be, tests need to be made to decide what is acceptable.

The pictures below give an idea of what happens when a TapeFormer is being used with the correct size cable and tape, and a smaller cable and tape. We cannot guarantee the performance of a TapeFormer that is being used with a smaller cable and tape that it was manufactured for.
