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.
