Abstract
Abstract Winding device with drive-roller drive for winding endless threads on a bobbin tube securely held by means of a chuck, with a pressure-operated rod axially movable in the chuck for releasing the chuck and an electric or a pneumatic or hydraulic drive motor for starting rotation of the empty bobbin or providing an additional drive moment in the chuck shaft.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A winding device according to claim 1, and further comprising a bobbin-changing device movable between at least two predetermined positions, said device having mounted thereon at least two of said chucks with respective pressure rods axially slidably mounted thereon, one of said positions being a position for operable engagement of said drive roller with said bobbin, and said drive motor being positioned for engagement of said coupling members in another of said predetermined positions for engagement of said coupling members and starting rotation of an empty bobbin placed on the respective chuck.
Claim 2
Dependent Claim
53 words
A winding device according to claim 1, one of said coupling members being a hollow coupling and the other of said coupling members being movable inside said hollow coupling with means operatively engaging said hollow coupling member, and said pressure rod-engaging means being mounted on the coupling member connected to said drive shaft.
Claim 3
Dependent Claim
70 words
A winding device according to claim 1, said coupling members comprising a first coupling disc yieldably mounted by spring means on said drive shaft, said disc being engageable with the end of said chuck shaft and axially aligned therewith, a central bore through said disc, and said pressure rod-engaging means being a member connected to said drive shaft and adapted to project through said bore and engage said pressure rod.
Claim 4
Dependent Claim
43 words
A winding device according to claim 1, said drive motor being mounted in a casing with its drive shaft projecting from said casing, and said means to axially shift said motor being fluid pressure-actuated means for shifting said motor axially in said casing.
Claim 5
Dependent Claim
28 words
A winding device according to claim 1 wherein said means for axially shifting said motor is a fluid pressure actuated means embodying a piston connected to said motor.
Claim 6
Dependent Claim
34 words
A winding device as claimed in claim 6, said piston being a collar on said motor, and said collar and motor being mounted in a casing and axially movable therein by fluid pressure means.
Claim 7
Dependent Claim
29 words
A winding device according to claim 7, and spring means for positioning the drive motor in the absence of application of fluid pressure in a mid-position in said casing.
Claim 8
Dependent Claim
37 words
A winding device according to claim 1, said coupling means including means providing a positive, non-slipping connection of said coupling members, and one of said coupling members embodying a spring-mounted synchronizing disc on the last-mentioned coupling member.
