Title: Ring rail lift control - determines balloon limit ring motion at spindle point
Inventor: IGEL WOLFGANG DIPL ING
IPC: D01H1/36
Filed: 1980-05-09
Abstract: The draw band for the ring rail lift mechanism and the balloon limit ring is linked to a limit control to determine the lift movement of the balloon limit ring at the spindle point zone. The lift movement limit control acts on the draw band after the mid-point of the movement, using a cam mounted coaxially with the drive roller for the band, with a flat surface of the cam coming after the centre of the lift in the cam rotation cycle, or the cam can be in a spiral shape. In an alternative form, the control can be in the form of a spring coming hard against a fixed limit stop when the balloon limit ring reaches a point close under the spindle point, and the position of the fixed limit stop can be adjusted. The spring control can also be used in conjunction with a sprung piston, linked to another section of the draw band, with the cylinder for the piston acting with a fixed limit stop. The design ensures that the suction cap and the balloon limit ring do not foul each other at their top positions to allow a catch hook to be inserted to trap a broken yarn, while the movement of the balloon limit ring is influenced as little as possible.
