Abstract
Abstract A bobbin slide for automatically guiding a bobbin on a thread respooling machine includes an elongated generally U-shaped housing which is pivoted about a horizontal axis at one end thereof. The other end of the housing is provided with a sloped portion disposed proximate a take-up finger which is adapted to receive the bobbin. A spring bias means is coupled to the housing at one end for urging the housing sloped portion towards the take-up finger. The weight of the bobbin on the housing causes the housing to move away from the take-up finger permitting the finger to enter the opening in the bobbin and thereby position it for use.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
118 words
A bobbin slide for automatically guiding a bobbin on a thread respooling machine comprises, in combination: (a) an elongated generally U-shaped housing, said housing being pivotable about a horizontal axis at one end thereof, the other end being provided with a sloped portion; (b) a take-up finger, said finger being disposed proximate to the sloped portion and adapted to receive said bobbin; (c) spring bias means coupled to said housing one end for urging said housing sloped portion towards said take-up finger; and (d) adjustable stop means for preventing said sloped portion of said housing from contacting said take-up finger by adjusting the distance from the edge of said sloped portion of said housing to said take-up finger.

Claim 3
Dependent Claim
43 words
A bobbin slide according to claim 1 wherein when said slide is in contact with said stop means the distance from the edge of said sloped portion to said take-up finger is less than the internal diameter of the smallest bobbin spool utilized.
Claim 4
Dependent Claim
43 words
A bobbin slide according to claim 1 wherein when said slide is in contact with said stop means the distance from the edge of said sloped portion to said takeup finger is greater than the wall thickness of the largest bobbin spool utilized.
Claim 5
Dependent Claim
32 words
A bobbin slide according to claim 1 wherein said sloped portion is sloped at an angle phi (φ) which is equal to the largest spin-on angle phi prime (φ') of the bobbin.
Claim 6
Dependent Claim
32 words
A bobbin slide according to claim 1 wherein said sloped portion is sloped at an angle phi (φ) which is smaller than the largest spin-on angle phi prime (φ') of the bobbin.
Claim 7
Dependent Claim
25 words
A bobbin slide according to claim 2 or 3 wherein said distance from the edge of said sloped portion to said take-up finger is adjustable.
Claim 8
Dependent Claim
