Method of intermittently severing continuously formed extrudate
Abstract
Abstract A CONTINUOUS EXTRUDATE IS BENT THROUGH AN ARC PRIOR TO ENTRY INTO A CUTTER UNIT. AS THE TUBING IN THE CUTTER UNIT IS HELD IN A FIXED POSITION, THE CONTINUING EXTRUSION OF THE EXTRUDATE RESULTS IN INMCREASING THE SIZE OF THE ARC. TWO LIMIT SWITCHES ARE PROVIDED, ONE POSITIONED SO THAT AS THE SIZE OF THE ARC IS INCREASED TO A PRESET AMOUNT, HE TUBING WILL TOUCH SAME AND THEREBY CAUSE THE CUTTING MECHANISM TO ADVANCE THE TUBING, THUS DECREASE THE SIZE OF THE ARC UNTIL IT CONTACTS THE SECOND LIMIT SWITCH WHICH STOPS THE MOVEMENT OF THE MATERIAL INTO THE CUTTER. THEREAFTER, THE PORTION OF THE EXTRUDATE ADVANCED INTO THE CUTTER IS HELD IN A STATIONARY POSITION AND CUT WHILE THE EXTRUSION CONTINUES.
