Abstract
Abstract A strand guide for strand winding machines arranged on a mounting movable away from the winding mandrel at a rate corresponding to the strand buildup whereby the angle of introduction of the strand to the wound package is maintained constant to avoid changes in winding tension. The strand guide mount is moved as a timed function in one example through the medium of a fluid drive including a precision control check.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
In a strand winding machine for winding strand into a package on a strand receiving form rotated about a winding axis, the improvement comprising a strand guide for guiding a strand onto said form, an actuator for moving said strand guide toward and away from the winding axis of said form, said actuator including a hydraulic cylinder, said actuator being connected by linkage to said strand guide, and control means free of the strand surface wound on said form for controlling said actuator in a manner correlated to the buildup of the strand surface wound on said form whereby said control means maintains said strand guide in spatial relationship to the strand surface wound on said form, said control means including a checking cylinder affixed to the actuator to control the rate of movement of the strand guide by controlling the speed of the actuator, and said control means including means for adjusting the checking cylinder to effect different speeds for the actuator.
Claim 2
Dependent Claim
163 words
In a strand winding machine for winding strand into a package on a strand receiving form rotated about a winding axis, the improvement comprising a strand guide for guiding a strand onto said form, an actuator for moving said strand guide toward and away from the winding axis of said form, said actuator including a hydraulic cylinder, said actuator being connected by linkage to said strand guide, and control means free of the strand surface wound on said form for controlling said actuator in a manner correlated to the buildup of the strand surface wound on said form whereby said control means maintains said strand guide in spatial relationship to the strand surface wound on said form, said control means including a checking cylinder affixed to the actuator to control the rate of movement of the strand guide by controlling the speed of the actuator, and said control means including means for adjusting the checking cylinder to effect different speeds for the actuator.
Claim 3
Dependent Claim
45 words
The combination according to claim 1 wherein said actuator for moving said strand guide includes a cam, a cam follower which is connected to said hydraulic cylinder, and means for adjusting the position of said cam to regulate the distance traveled by said strand guide.
Claim 4
Dependent Claim
25 words
The combination according to claim 1 wherein said strand guide includes a traverse mechanism for guiding the strand over the face of said receiving form.
Claim 5
Dependent Claim
156 words
The combination according to claim 1 wherein said actuator includes a cam and a cam follower connected to said hydraulic cylinder which is pivotally mounted and develops relative motion between said cam and said cam follower, a pivotally mounted actuator bar and a slide, said bar being connected to said cylinder at the pivotal end thereof, said slide being connected to said cam follower and said hydraulic cylinder, and said slide being slideable within said bar to cause said cylinder and bar to swing when said cam is fixed at an angle to said bar upon actuating said cylinder, said linkage including linkage for converting linear motion to rotational motion to swing said strand guide; and said control means includes a needle valve for adjusting the checking cylinder which controls the speed of said hydraulic cylinder; and including a traverse mechanism for said strand guide to guide the strand over the face of said receiving form.
