Abstract
Abstract A twisting spindle driven by an individual electric motor wherein fastening of the body of the motor as well as maintaining and guiding of the barrel of the spindle are effected via a rigid sleeve surrounding the barrel, the sleeve passing through the frame and serving as a cage for anti-friction bearings which permit rotation of the spindle, and having at its ends two collars, one fastened elastically to the frame and the other rigidly connected to the body or stator of the motor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
100 words
A twisting spindle driven by an individual electric motor, the spindle comprising: a spindle barrel mounted on a support frame by means permitting free rotation of the barrel; a motor having a rotor which is rigidly connected to the spindle barrel, with the rotor or stator of the motor rigidly connected to the support frame by a sleeve extending therethrough and surrounding the barrel of the spindle; the sleeve having an upper collar elastically fastened to the support frame and a lower collar rigidly connected to the body or stator of the motor, with anti-friction bearings contained within the sleeve.
Claim 2
Dependent Claim
100 words
A twisting spindle driven by an individual electric motor, the spindle comprising: a spindle barrel mounted on a support frame by means permitting free rotation of the barrel; a motor having a rotor which is rigidly connected to the spindle barrel, with the rotor or stator of the motor rigidly connected to the support frame by a sleeve extending therethrough and surrounding the barrel of the spindle; the sleeve having an upper collar elastically fastened to the support frame and a lower collar rigidly connected to the body or stator of the motor, with anti-friction bearings contained within the sleeve.
Claim 3
Dependent Claim
70 words
The spindle of claim 1, wherein the elastic attachment of the upper collar of the sleeve to the support frame is accomplished by the placement of elastic dampening studs between an upper portion of the support frame and a lower portion of the upper collar and additional elastic dampening studs placed in contact with a lower portion of the support frame with a bolt extending through the elastic attachment assembly.
Claim 4
Dependent Claim
15 words
The twisting spindle of claim 1, wherein the motor is an asynchronous two-pole electric motor.
Claim 5
Dependent Claim
21 words
The twisting spindle of claim 1 additionally comprising an individual braking system surrounding the twisting spindle having a jaw-type brake thereabout.
