Traverse Wound Bobbins

SJA Film Technologies are one of the leaders in UK spooling technology.

We currently have state of the art 12 and 24 head traverse wound bobbin machines on site. Both machines are capable of converting extensible / non extensible, adhesive / non adhesive substrates from 2mm through to 40mm width. This technique gives the converter the advantage to change from conventional pancakes (pads) to a bobbin.

Changeover times are made irrelevant by moving from pads (pancakes) to bobbins. Efficiencies can increase up to 1000%, and, waste reduces to as little as 1%.

This method enables the joining together of longer lengths of material, and, in most cases the bobbin meterage can be as much as 40 times the linear metres normally contained on a pancake.

SAVE time.  REDUCE waste.  INCREASE profitability.

To assist in the transition of pads to bobbins, we can supply various de-spooling equipment that take the bobbin to a take-off point which enables the tape to be fed straight into the relevant conversion machine. This de-spooling equipment eradicates the uncertainty surrounding changing from pads to bobbins.

We can also apply a secondary release tape to alleviate adhesive seepage layer to layer.

Double wound spool technology is also available.

We can also trade spool your materials to your requirements. Please contact our offices for further details.
