摘要:
A sealing jaw apparatus for a film wrapping machine utilizes a continuous web of thermoplastic film. The sealing jaw apparatus includes a first jaw unit to one side of a film travel path. The first jaw unit includes spaced-apart clamp arms and a heated sealing bar located between the spaced-apart clamp arms. The heated sealing bar includes spaced-apart noses defining a slot therebetween. A second jaw unit is to an opposite side of the film travel path. The second jaw unit includes spaced-apart gripping surfaces that are engaged by the spaced-apart clamp arms for gripping the thermoplastic film. Spaced-apart sealing surfaces are engaged by the noses of the heated sealing bar for sealing the thermoplastic film at spaced-apart locations in a film running direction. A knife assembly severs the thermoplastic film between the spaced-apart locations.
