Abstract
A method and apparatus for the manufacture of collar inserts made of a base insert and a seal insert, by which the base insert and the seal insert are introduced in the sealing press lying aligned on each other. The base insert and the seal insert are provided with at least two truing openings, respectively, corresponding in arrangement to truing mandrels on a support, the latter being insertable in a sealing press with the base insert and the seal insert disposed on each other aligned with the truing mandrels inserted in the respective truing openings of the inserts.
Claims11
A method for the production of collar inserts comprising a base insert and a seal insert, comprising the steps of
- forming by a stamp out operation a larger base insert and a smaller seal insert, respectively, with at least two truing slits, corresponding in arrangement to respective truing mandrels on a support, such that said inserts are shaped in a form of a collar insert having two points for the collar of a garment,
- laying said base insert and said seal insert on each other on the support aligned with the truing slits guided-in on the corresponding truing mandrels, respectively, with a substantially symmetric uniform edge spacing of the edges of said base insert and said seal insert relative to each other, and thereafter
- introducing the support together with the base insert and the seal insert lying aligned thereon in a sealing press,
- sealing said inserts in said sealing press with the simultaneous retracting of said truing mandrels from said slits, and
- inserting the sealed inserts between material sides of a double layer collar.
