Patent DE-19653389-A1 (DE)
Title: End preparation for start=up in rotor spinning
Inventor: OLBRICH ANDREAS DR ING
IPC: B65H69/06
Filed: 1996-12-20
Abstract: The end of a rotor spun yarn with characteristic wrapper fibres is prepared for start-up or splicing by pneumatic untwisting. A length of yarn (5) is gripped (6,7) and held under tension. A tool (14) opens the wrapper fibres (18) and pushes them towards the yarn end by a relative movement between tool and yarn. The cleared yarn section is cut at a certain distance from one clamp and untwisted (10) pneumatically. Preferably the yarn is held in a suction nozzle (3) while clamps (6,7) are adjusted to bring the yarn (5) into the optimum position. A roller (14), fitted with pins (16) arranged in a spiral pattern and with its axis inclined at an acute angle to the yarn, rotates rapidly while moving (23) along the yarn. The wrapper fibres are opened and pushed along the yarn towards the end where they are sucked away. The yarn is cut and an arm (35) swings about a hinge (8) to a position (37) near a pneumatic untwisting device (10) which opens out the yarn end.
