ABSTRACT:
An improved film cutter for severing sheets of soft stretch film which is drawn in a plane into a wrapping machine from a continuous source of such film comprises a first elongated knife blade extending laterally across the plane defined by the film and having a serrated cutting edge facing the film. A knife bracket extends laterally across the opposite side of the film plane and forms a channel such that the first knife blade may be moved or inserted into the channel to sever the film. The knife bracket comprises an elongated first member, with a knife mounting bar secured thereto and spaced therefrom to define the channel. The knife mounting bar includes a flange extending away from the channel and toward the film oriented at an acute angle to the knife mounting bar such that the extended edge of the flange forms a thin film contacting edge of the channel. A second knife blade is secured parallel to the knife mounting bar and spaced therefrom, with the second knife blade having a serrated cutting edge facing the film and extending in the channel to a point short of the film contacting edge of the channel.
