Abstract
The apparatus includes an operating unit, which can be a welding unit for welding a closing film to an edge zone of a containing element or a separating unit for separating containing elements from portions of sheet material. The apparatus includes a control unit programmed to enable the operating unit to selectively process a continuous strip of containing elements or discrete groups of containing elements.
Claims22
A welding apparatus, comprising
- a welding unit for welding a closing film to an edge zone of at least one containing cavity surrounded by said edge zone and being formed from a thermoformable sheet by a forming apparatus upstream of said welding unit;
- a control unit connected with said welding unit for selectively processing a continuous strip of said containing cavities or discrete groups of said containing cavities;
- a selecting device connected with said control unit for selecting a first operating condition of said welding unit for processing said continuous strip of containing cavities and a second operating condition of said welding unit for processing discrete groups of said containing cavities;
- a connecting device for connecting said control unit with a control unit of said forming apparatus and/or with a control unit of a separating apparatus arranged downstream of said welding unit;
- and
- a cutting unit connected with said welding unit for removing a portion of said closing film, whereby after said closing film has been welded along said edge zone to a sheet material in which said container cavity is formed, a zone of said sheet material remains uncovered by said closing film.
