Abstract

"Device for cutting the parson in machines for manufacturing hollow bodies by extrusion-blowing", characterized in that it is equipped with a device for cutting the descent of the pair, continuously extruded during the periods of stop due to incidences of operation , by moving the device to the cutting member in the trajectory of the pair, at a rate much higher than that to which the molds pass during normal periods of operation.
