Abstract
A process for the manufacture of a plastic film in sheets of synthetic material, partially stretched, according to the patent no. 379,505, by joining layers of synthetic material in fusion flow, and then immediately stretching the sheet plastic thus formed, for which are introduced from a nozzle head in a common extrusion channel two layers of thermoplastic synthetic material with a lower melting temperature, and between these two layers a thermoplastic synthetic material with a higher melting temperature, which together with the two layers are introduced from the nozzle head into the common extrusion channel, and the assembled layers are also conducted by a cooling path of the common extrusion channel, until the temperature has fallen below the highest melting temperature of the material synthetic thermoplastic introduced between the two layers, but not below the melting temperature of the layers themselves, and until the still plastic layers, supported as sliding layers against the walls of the extrusion channel, generate, due to their adhesion to the thermoplastic synthetic material introduced between them, of higher and already solidified melting temperature, and due to its friction on the walls of the extrusion channel, a tear resistance that allows immediate drafting at the exit of the extrusion channel, characterized in that the thermoplastic synthetic material of higher melting temperature is introduced between the layers in the form of threads of individual streams.
