Abstract
Abstract A traverse apparatus for guiding linear product or the like in winding the product on a reel, which traverse apparatus includes an arm pivotally carried by a traverser so as to extend toward the reel, and a product-engaging guide member pivotally connected to the extended free end of the arm. The guide member engages the product at the point where the product comes in touch with the drum portion of the reel, and the longitudinal axis of the guide member is kept in parallel with the longitudinal direction of that portion of the product which engages the guide member, so that the longitudinal axial direction of the guide member and the longitudinal direction of the arm define an angle theta therebetween. The traverser is controlled in such a manner that the aforesaid angle theta is kept constant by moving the traverser in parallel with the axis of rotation of the reel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A winding traverse apparatus for winding a linear product on a reel, comprising a traverser adapted for movement relative to the reel and in a path parallel to the axis of rotation of the reel, an arm pivotably connected to the traverser, a productengaging guide member pivotably secured at the free end of said arm and having a longitudinal axis parallel to the longitudinal axis of the product portion it engages, an angle detector mounted on said arm and connected to said guide member and adapted to detect angular displacement of the guide member relative to said arm, an angle setter, a drive unit adapted to impart relative movement between said traverser and said reel, and means to actuate said drive unit in response to change in angular displacement of said guide member from a set position of said angular setter.
Claim 2
Dependent Claim
141 words
A winding traverse apparatus for winding a linear product on a reel, comprising a traverser adapted for movement relative to the reel and in a path parallel to the axis of rotation of the reel, an arm pivotably connected to the traverser, a productengaging guide member pivotably secured at the free end of said arm and having a longitudinal axis parallel to the longitudinal axis of the product portion it engages, an angle detector mounted on said arm and connected to said guide member and adapted to detect angular displacement of the guide member relative to said arm, an angle setter, a drive unit adapted to impart relative movement between said traverser and said reel, and means to actuate said drive unit in response to change in angular displacement of said guide member from a set position of said angular setter.
Claim 3
Dependent Claim
76 words
A winding traverse apparatus according to claim 1, wherein said product-engaging guide member is a guide shoe having a side wall engageable with a last wound turn of the product and a product-engaging groove for urging a portion of the product being just wound to the reel, the width of the guide shoe taken at right angles to said longitudinal direction thereof being identical with the pitch of the turns of the product on the reel.
Claim 4
Dependent Claim
30 words
A winding traverse apparatus according to claim 1, wherein said product-engaging guide member consists of one or more pulleys having grooves engageable with portion of the product being just wound.
Claim 5
Dependent Claim
52 words
A winding traverse apparatus according to claim 1, wherein said angle detector is a potentiometer having a winding secured to the arm and a rotatable contact secured to a vertical shaft so as to slidingly contact at different points of the winding in response to the angular displacement of the guide member.
Claim 6
Dependent Claim
83 words
A winding traverse apparatus according to claim 1, wherein said drive unit actuating means consists of a comparator capable of producing an output representing the differential betweeN the output from the angle detector and preset value of the angle setter, a reversible motor, a pair of sets of silicon controlled rectifiers connected in parallel with each other in a power source circuit of the reversible motor, and a wiring means connecting the output from the comparator to gates of the sets of SCR''s.
Claim 7
Dependent Claim
16 words
A winding traverse apparatus according to claim 1, wherein said angle detector is a Selsyn device.
Claim 8
Dependent Claim
26 words
A winding traverse apparatus according to claim 1, wherein said traverser further has a product paying means paying the product to the reel along the arm.
Claim 9
Dependent Claim
30 words
A winding traverse apparatus according to claim 1, including a fluid pressure cylinder inserted between said traverser and said arm, whereby said guide member urges the product to the reel.
Claim 10
Dependent Claim
28 words
A winding traverse apparatus according to claim 1, including a spring inserted between said traverser and said arm, whereby said guide member urges the product to the reel.
