Abstract
A heat sealing machine having platen means for melting at least a portion of the object to be sealed, said platen means being mounted on a carriage means for moving said platen means along at least a first axis, is described having the improvement wherein track means are provided for allowing movement of the platen means with respect to the carriage means along a second axis which is perpendicular to said first axis. Additionally, the present invention provides a pin means for fixedly engaging said platen means at a precise, predetermined position with respect to said carriage means, as well as providing for carriage and extension portions of said track means which provide for the quick interchange of platens from reserve to operating positions. Various features of the present invention allow for the preheating and prealignment of reserve platens, whereby substitution of the desired platen is safe, simple, fast and reliable.
