Abstract
Abstract Apparatus for cutting an elongated strip from the tread of a vehicle tire having rotating cutters spaced from each other the width of the strip to be cut. Roller is mounted for movement toward and away from cutters with axis of roller being parallel to axis of rotation of cutters. Roller is adapted to enter tire and engage opposite side of tread from side thereof engaged by cutters to force the tread into cutting relation with cutters and impart rotary motion to tire being cut.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
In apparatus for cutting a strip of resilient material from the tread of a vehicle tire comprising: a. a supporting frame, b. at least two disc-like cutters supported for rotation on said frame and spaced from each other a distance equal the width of the strip of material to be cut, c. means imparting rotation to said cutters, d. a roller mounted on said frame and adapted for movement toward and away from said cutters with the axis of said roller being parallel to the axis of rotation of said disc-like cutters, e. said roller being adapted to enter a vehicle tire to be cut and engage the opposite side of the tread of said tire from the side thereof engaged by said disc-like cutters to force said tread into cutting relation with said cutters and impart rotation to said tire upon movement of said roller toward said disc-like cutters with the tire therebetween whereby an annular strip of the tread is cut by said cutters as rotary motion is imparted to said tire, and f. power means to move said roller into and out of driving engagement with said opposite side of the tread of said tire.
Claim 2
Dependent Claim
198 words
In apparatus for cutting a strip of resilient material from the tread of a vehicle tire comprising: a. a supporting frame, b. at least two disc-like cutters supported for rotation on said frame and spaced from each other a distance equal the width of the strip of material to be cut, c. means imparting rotation to said cutters, d. a roller mounted on said frame and adapted for movement toward and away from said cutters with the axis of said roller being parallel to the axis of rotation of said disc-like cutters, e. said roller being adapted to enter a vehicle tire to be cut and engage the opposite side of the tread of said tire from the side thereof engaged by said disc-like cutters to force said tread into cutting relation with said cutters and impart rotation to said tire upon movement of said roller toward said disc-like cutters with the tire therebetween whereby an annular strip of the tread is cut by said cutters as rotary motion is imparted to said tire, and f. power means to move said roller into and out of driving engagement with said opposite side of the tread of said tire.
Claim 3
Dependent Claim
53 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 1 in which said roller is of a length greater than the distance between said disc-like cutters and annular grooves are provided in said roller for receiving the peripheral edges of said disc-like cutters.
Claim 4
Dependent Claim
90 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 1 in which said roller is mounted for rotation at one end of at least one arm with the other end of said arm being mounted for pivotal movement whereby said one end is adapted to move toward and away from said cutters, and said power means is operatively connected to said arm for moving said arm relative to said cutters and said opposite side of the tread of said tire.
Claim 5
Dependent Claim
42 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 3 in which said other end of said arm is carried by a shaft which is mounted for rotation on said supporting frame.
Claim 6
Dependent Claim
47 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 4 in which saId shaft is operatively connected to a fluid pressure operated cylinder so that said shaft is rotated an angular distance upon actuation of said cylinder.
Claim 7
Dependent Claim
47 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 5 in which a stop member is carried by said shaft in position to engage a stationary stop carried by said frame to limit rotation of said shaft.
Claim 8
Dependent Claim
98 words
Apparatus for cutting a strip of resilient material from the tread of a vehicle tire as defined in claim 6 in which said disc-like cutters are mounted adjacent one end of a shaft which is mounted for rotation on said frame, with another disc-like cutter mounted adjacent the other end of said shaft and a support member is carried by said frame beneath said another cutter for supporting and guiding a strip of resilient material transversely into engagement with said another cutter, there being a recess in said support member for receiving the periphery of said another cutter.
