Abstract
An apparatus for cutting a continuously manufactured tube including a knife-holder carriage which is movably mounted for translation and which is provided with a knife activator, a return mechanism for returning the carriage to an initial position following each cutting of a tube section, a driving mechanism for moving the carriage which includes a first driving motor and a first clutch system and a device for determining a section length of tube to be obtained operably connected to control the function of the first clutch system after each cutting based on the desired length of tube to be cut.
Claims17
An apparatus for cutting a continuously manufactured tube moving in translation at a preselected speed, said apparatus comprising a knife-holder carriage which is movably mounted for translation and which is provided with means for activating knives, means for returning said carriage to an initial position following each cutting, a driving means for moving said knife-holder carriage, said driving means comprising a first rotating motor, which is guided in rotation as a function of the speed of translation of said tube, and a first clutch system, and means for determining a section length of tube to be obtained, operably connected to control the function of said first clutch system after each cutting, based upon said length of tube, wherein said clutch system is adapted to be disengaged during penetration of said knives in a side of said tube at least until a cutting action of said knives is stopped, so that said knife-holder carriage and said driving means are driven during said penetration of said knives by said tube.
