Abstract
A system and method for producing a medical bag with an HF welder that uses upper and lower dies each having a plurality of electrode lamellae arranged such that they are alternatingly polarized relative to adjacent lamellae and opposing lamellae. Interspersed dielectric materials may be used to impart contours onto the film material to produce a patterned bag.
Claims19
A tool for HF welding an inserted part with an axial direction to two films to form a bag, comprising:
- an upper die;
- a lower die;
- wherein each of said upper die and said lower die includes a plurality of electrode lamellae arranged such that said electrode lamellae are alternatingly polarized along said axial direction and oppositely polarized perpendicular to the axial direction.
A system for producing a bag for medical purposes, comprising:
- a film feeder;
- a filling station;
- and,
- a welding station including a tool having:
- an upper die and a lower die;
- wherein each of said upper die and said lower die includes a plurality of electrode lamellae arranged such that said electrode lamellae are alternatingly polarized along an axial direction and oppositely polarized perpendicular to the axial direction.

A method of producing a bag for medical purposes comprising:
- guiding two films and an inserted part with an axial direction into a welding station, the welding station including opposing dies, each of said opposing dies including a plurality of electrode lamellae arranged such that said electrode lamellae are alternatingly polarized relative to adjacent lamellae and oppositely polarized relative to opposing lamellae;
- positioning the inserted part between the two films;
- laying the two films against the sides of the inserted part;
- and,
- subjecting the electrode lamellae to high-frequency electricity, thereby welding the two films around the inserted part.
