Abstract
A packaging machine for wrapping packing pieces with packing film. The packing machine includes a transport device for the packing pieces arranged in a transport channel, at least one pulling device for the packing film and a film cutting and welding device which, when operated, pulls one film section from the pulling device and welds it to another film section for forming a film tube surrounding the packing piece. The packing machine is design to prevent a run-up of the film pulled by the pulling device into the transport channel by the inclusion of a narrow through gap for the packing film. The gap limits the passage of the film when the tension on the film is reduced.

A packaging machine for wrapping packing pieces which inhibits run-up of packing film into a transport channel during the wrapping of said packing pieces with said packing film comprising a transport device to transport said packing pieces in a transport channel to a wrapping location, an upper and lower packing film delivery arrangement, a film cutting and welding device to at least partially cut said packing film at said wrapping location and to at least partially weld said packing film together after said packing film has been at least partially wrapped about one of said packing pieces, said upper and lower packing film delivery arrangement each including at least one source of packing film and at least one guide arrangement to guide each of said packing films to said wrapping location, said upper packing film delivery arrangement including a pre-set narrow gap, said narrow gap positioned upstream from said transport channel and having a size to at least partially control passage of said packing film through the narrow gap and to said wrapping location thereby at least partially inhibiting run-up of said packing film into said transport channel after said packing piece has been at least partially wrapped, said narrow gap having a pre-set size that is larger than a thickness of said wrapping film.
A packaging machine for wrapping packing pieces which inhibits run-up of packing film into a transport channel during the wrapping of said packing pieces with said packing film comprising a transport device to transport said packing pieces in a transport channel to a wrapping location, an upper and lower packing film delivery arrangement, a film cutting and welding device to at least partially cut said packing film at said wrapping location and to at least partially weld said packing film together after said packing film has been at least partially wrapped about one of said packing pieces, said upper and lower packing film delivery arrangement each including at least one source of packing film and at least one guide arrangement to guide each of said packing films to said wrapping location, said upper packing film delivery arrangement including a packing film buffer and a pre-set narrow gap, said packing film buffer positioned between said source of packing film and said narrow gap, said packing film buffer designed to at least partially support packing film that has accumulated between said narrow gap and said source of packing film, said packing film buffer being at least partially formed of a flexible antistatic material, said packing film buffer being non-planar and having an incline of an angle of about 15–45° said narrow gap positioned upstream from said transport channel and having a size to at least partially control passage of said packing film through the narrow gap and to said wrapping location thereby at least partially inhibiting run-up of said packing film into said transport channel after said packing piece has been at least partially wrapped, said narrow gap having a pre-set size that is greater than a thickness of said packing film and being up to about 2 times a thickness of said packing film.
A packing machine for wrapping packing pieces with packing film, said packaging machine comprising:
- a transport channel;
- a transport device for transporting said packing pieces in said transport channel;
- a cutting and welding device for cutting and welding said packing film;
- and,
- at least one pulling device for said packing film, said pulling device including a pre-set narrow gap for passage of said packing film, said narrow gap being limiting above and below by ledges, at least one of said ledges being a stop ledge for said packing film, said narrow gap arranged at a pulling side of said pulling device, said narrow gap having a pre-set size that is greater than a thickness of said packing film, said pulling side being arranged towards said film cutting and welding device.
