Reinforcing film sealing unit for open-end 6 and 8 mm. zippers
Description
For metal, coil, and plastic molded zippers.
This unit is designed for sealing the plastic reinforcing film to the tape: this operation is required, before attaching pin and box, to the open-end zippers.
It is composed of the sealing unit and the EWT panel, responsible for the power supply and the temperature control.
The reinforcing film is coated with a hot-melt resin that melts at a temperature lower than that to which the film itself melts.
This unit is therefore required to press the film against the zipper tape, and, at the same time, to bring the hot-melt resin to the melting temperature.
The result of this operation is a reinforcing film perfectly fixed on the zipper tape, thanks to the melting, on the latter, of hot-melt resin.
The duration of this pressing action, and its value, can be partly decided by the operator to obtain a good compromise between an optimal application of reinforcement and acceptable production rates.
The reinforcing film is applied only on the front side of the open-end zipper (the side where there is the puller of the slider), and for this reason, it is twice as thick as those normally used for application on both sides (0.28 mm.).
Once the application of reinforcing film is done, and before applying pin and box for obtaining a open-end zipper, three more steps are needed:
1) Removal of the reinforcing film between the two cords of the zipper tape: by hand or by the OEL tool.
2) Cutting the reinforced part of the zipper tape to the right measure for the insertion of pin and box: by hand or by the OET tool.
3) Lateral trimming of the excess of the reinforcing film: only manually
Each of these three operations can be easily accomplished through the use of good sharp scissors. For the second operation, however, we offer a specific tool that will facilitate the operations and make more consistent quality results.
The unit has no parts subject to wear.
