  • Patent number: 4944668
    Abstract: A device for gripping and pulling a length of thermoplastic sheet softened to be moldingly formed at the front and rear edges, which are otherwise inevitably made to be concave, so as to hold edges substantially straight. The device uses at least two pairs of lower and upper gripping members arranged to be vertically movable so as to grip the above front and rear edges. Two pairs of pull levers each cooperating with one of the pair of lower and upper gripping members operate so as to grip the front and rear edges in advance of the gripping by the gripping members and pull to straighten the concaved edges which are then gripped by the gripping members.
