Abstract
The thread reeling apparatus includes a rotary cam drum with a traversing thread guide assembly used to guide a thread from a delivery mechanism to a bobbin or thread package. A roller having a smooth, peripheral surface is interposed at a location downstream of the rotary cam drum along which the traversing thread guide assembly moves back and forth. A further traversing thread guide assembly located downstream of the smooth roller receives the thread from the smooth roller and transfers the same on to a bobbin or thread package driven by a friction roller. The disposition of the smooth roller and further traversing thread guide assembly controls the tension of the thread along the thread path.
Claims6
An apparatus for reeling thread on a bobbin, said apparatus comprising:
- (a) a rotary cam drum having a helical groove extending along the longitudinal axis thereof,
- (b) a first traversing thread guide assembly mounted to move along said helical groove and effective to guide the thread to-and-fro along the longitudinal axis of the rotary cam drum,
- (c) tension controlling means located between the rotary cam drum and the bobbin to receive the thread from the first traversing thread guide assembly for controlling the tension of the thread, and
- (d) a friction roller for rotating the bobbin,
- (e) said tension controlling means including a smooth roller located downstream from said first traversing thread guide assembly for receiving a thread on its smooth peripheral surface and a second traversing thread guide assembly between the smooth roller and the friction roller,
- (f) said second traversing thread guide assembly being effective to guide the thread between the smooth roller and the friction roller.
