Abstract
Abstract A method and apparatus for mechanically booking tire treads. Tire treads sequentially advancing along a first conveyor are fed to a rotating pick-up drum, where they are lifted onto a second conveyor. The second conveyor has rotary arms disposed thereon that project the tread through space onto the leaves of a tread truck. The tread truck includes an indexing unit that individually indexes each of the separate tread truck leaves into a horizontal position to receive a tread thereon. Means is provided to progressively vary the trajectories of the projected treads in order to insure that the treads will be deposited on the proper truck leaves in undistorted condition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
71 words
A tread booking apparatus for sequentially receiving a plurality of tire treads at a common station therein and for transferring said treads selectively to a plurality of spaced receiving stations adjacent to said apparatus, comprising: conveyor means for sequentially delivering said treads to said common station; and aerial projection means sequentially engageable with said treads at said common station for transferring said treads through selected airborne trajectories to said receiving stations.
Claim 2
Dependent Claim
71 words
A tread booking apparatus for sequentially receiving a plurality of tire treads at a common station therein and for transferring said treads selectively to a plurality of spaced receiving stations adjacent to said apparatus, comprising: conveyor means for sequentially delivering said treads to said common station; and aerial projection means sequentially engageable with said treads at said common station for transferring said treads through selected airborne trajectories to said receiving stations.
Claim 3
Dependent Claim
65 words
Apparatus as described in claim 1, wherein said conveyor means includes: a first conveyor for delivering treads sequentially to said tread booking apparatus; a second conveyor for receiving treads from said first conveyor and delivering said treads to said common station; and means intermediate said first and second conveyors for turning over said treads as they pass from said first conveyor to said second conveyor.
Claim 4
Dependent Claim
35 words
Apparatus as described in claim 2, wherein said aerial projection means transfers said treads through airborne trajectories in which said treads are turned over as they pass from said common station to said receiving stations.
Claim 5
Dependent Claim
23 words
Apparatus as described in claim 3, wherein said turn over means intermediate said first and second conveyors comprises a rotating tread engaging element.
Claim 6
Dependent Claim
29 words
Apparatus as described in claim 4, wherein said rotating tread engaging element comprises a drum having a plurality of tread penetrating pins disposed about the circumference of the drum.
Claim 7
Dependent Claim
70 words
Apparatus as described in claim 1, wherein said conveyor means is horizontally disposed and includes a plurality of longitudinally spaced, transverse rollers positioned at said common station, and wherein said aerial projection means includes a rotary assembly having a plurality of arms interleaved with said rollers, said arms being upwardly movable between said rollers to engage said treads at said common station and remove said treads from said conveyor means.
Claim 8
Dependent Claim
58 words
Apparatus as described in claim 6 and further including means for intermittently driving said rotary assembly through a 180* rotary cycle during which cycle a tread is engaged by said arms at said common station, said tread is lifted from said conveyor means and said tread is aerially projected through a predetermined trajectory to a predetermined receiving station.
Claim 9
Dependent Claim
35 words
Apparatus as described in claim 7 and further including means cooperative with said driving means for selectively varying the rotational speed of said rotary assembly to selectively vary the trajectories of the aerially projected treads.
Claim 10
Dependent Claim
36 words
Apparatus as described in claim 1 wherein said aerial projection means transfers each of said treads so engaged through a selected one of a plurality of airborne traJectories to a respective one of said receiving stations.
Claim 11
Dependent Claim
19 words
Apparatus as described in claim 9 wherein said trajectories each correspond to a different one of said receiving stations.
Claim 12
Dependent Claim
30 words
Apparatus as described in claim 1 and further including a tread truck comprising a plurality of vertically spaced leaves for receiving said aerially projected treads adjacent to said common station.
