Embodiment Construction

[0033]FIG. 1 to 3 show a film delivery device for a wrapping machine (not shown) for delivering a wrapping film 1 around an article to be wrapped up. FIG. 3 shows that the wrapping film 1 has a first face 2 and a second face 3.

[0034]The film delivery device comprises a first assembly 4 which can be connected to the wrapping machine. The wrapping machine in which the presented film delivery device can be used may be any wrapping machine of the known type, such as[0035]a rotating-arm-type wrapping machine in which the film delivery device is connected to a rotating arm for rotating the film delivery device relative to a stationary article to be wrapped up,[0036]a ring-type wrapping machine in which the film delivery device is connected to a wrapping ring for rotating the film delivery device relative to a stationary article to be wrapped up, or[0037]a column-type wrapping machine in which the film delivery device is connected to a stationary column and the article to be wrapped up is ...

Abstract

A film delivery device comprising a first assembly (4) which can be connected to a wrapping machine and a second assembly (5) which is pivoted to turn, relative to the first assembly (4), about a horizontal hinge axis (6) between a closed position (I) and an open position (II). A first prestretch roller (7) is in the first assembly (4). A second prestretch roller (8) is in the second assembly (5). The film can be threaded by S-threading between the prestretch rollers (7, 8). The second assembly (5) is hinged at the lower end to the lower end of the first assembly (4) to turn about said horizontal hinge axis (6). The second assembly (5) comprises a pivoted and spring-loaded first deflecting roller (22) which is arranged downstream relative to the first prestretch roller (7). In the open position (II) of the second assembly (5), that part of the first deflecting roller (22) which is close to the lower end thereof is resting against the surface of the first prestretch roller (7).

Description

FIELD OF THE INVENTION[0001]The invention relates to a film delivery device as defined in the preamble of claim 1.BACKGROUND OF THE INVENTION[0002]Previously known from publication U.S. Pat. No. 6,082,081, is a film delivery device for a wrapping machine for delivering a wrapping film around an article to be wrapped up. The film delivery device comprises a first assembly which can be connected to the wrapping machine. Further, the film delivery device comprises a second assembly which is pivoted at the upper end to the upper end of the first assembly to turn about a horizontal hinge axis between a closed position and an open position.[0003]The film delivery device also comprises a prestretch device comprised of two prestretch rollers. It comprises a first prestretch roller which is arranged to the first assembly in substantially vertical direction and arranged to be rotated at a first peripheral speed. Further, the film delivery device comprises a second prestretch roller which is a...
