Abstract
An apparatus for winding a yarn onto a bobbin wherein the apparatus includes: a finger-shaped yarn guide supported along a first axis orientated at right angles to the bobbin axis, the yarn guide being subject to an oscillating motion about the first axis; and energy storage mechanisms for controlling the deceleration and acceleration of the yarn guide in short regions near reversing points for the yarn guide motion, wherein the position of the energy storage mechanisms is adjustable.
Claims13
An apparatus for winding a yarn onto a bobbin, said apparatus comprising:
- a yarn guide supported along a first axis orientated at right angles to the bobbin axis and subject to a first oscillating displacement motion;
- a motor coupled to said yarn guide for applying said first oscillating displacement force to said yarn guide and positioning said yarn guide between corresponding reversing points;
- and
- position controllable energy storage mechanisms detached from said yarn guide for controlling the deceleration and acceleration of said yarn guide during reversal of motion thereof in a short region proximal to each of said reversing points, wherein the position of said energy storage mechanisms with respect to said yarn guide is controllable during operation of said apparatus.
