Abstract
Abstract A rotary conveyor for moving work pieces mounted on a mandril through a plurality of work stations is provided where the manufacturing steps at each work station require different time intervals to carry out; to reduce the dwell time of the rotary table, the work tool requiring the longest dwell period is mounted directly on the table at each mandril position so as to be movable through all of the work stations with each work piece; a cam surface and cam follower arrangement are provided for moving the work tool into and out of the working position at selected work stations.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
90 words
Apparatus for the production of a work piece including a plurality of mandrils each mounted in spaced relation to one another on a rotary member, said rotary member being mounted for rotation about an axis to move each mandril through a plurality of work stations, the improvement comprising: said rotary member having working means mounted thereon adjacent each said mandril for performing a production step, each said working means being movable relative to said rotary member between a working and non-working position in response to rotation of said rotary member.
Claim 2
Dependent Claim
90 words
Apparatus for the production of a work piece including a plurality of mandrils each mounted in spaced relation to one another on a rotary member, said rotary member being mounted for rotation about an axis to move each mandril through a plurality of work stations, the improvement comprising: said rotary member having working means mounted thereon adjacent each said mandril for performing a production step, each said working means being movable relative to said rotary member between a working and non-working position in response to rotation of said rotary member.
Claim 3
Dependent Claim
15 words
The apparatus as claimed in claim 1 wherein said working means comprises a mold member.
Claim 4
Dependent Claim
74 words
The apparatus as claimed in claim 2 wherein said rotary member has mounting means for mounting said mold member for movement between said working and non-working positions, said mounting means including a pair of spaced arms on which said mold member is movable towards and away from said rotary member, said spaced arms being pivotable about an axis to bring said mold member into juxtaposition with a work piece mounted on said adjacent mandril.
Claim 5
Dependent Claim
25 words
The apparatus as claimed in claim 3 wherein said rotary member includes a fixed cam surface and each said mounting means includes a cam follower.
Claim 6
Dependent Claim
46 words
The apparatus as claimed in claim 4 wherein said cam surface is recessed with respect to said rotary member to effect movement of said mounting means from said non-working to said working position as said rotary member moves through a selected number of said work stations.
Claim 7
Dependent Claim
48 words
The apparatus as claimed in claim 5 wherein said rotary member rotates in a plane and said pivot axis of each of said mounting means lies in said plane, said cam surface being disengaged from each said cam follower when said mounting means is in said working position.
Claim 8
Dependent Claim
52 words
The apparatus as claimed in claim 4 wherein said arms include a stirrup on which said cam follower is mounted, said cam follower comprising a roller mounted on a shaft fixed to said stirrup and a spring urging said roller against said cam surface when said arms are in said non-working position.
Claim 9
Dependent Claim
62 words
The apparatus as claimed in claim 3 wherein at one of said work stations, means are provided for moving a said mold member on said arms at said work station towards said mandril located at said work station and at another work station, means are provided for moving a said mold member away from a said mandril at said other work station.
Claim 10
Dependent Claim
23 words
The apparatus as claimed in claim 3 wherein spring means are provided for urging said mold member towards said mandril on said arms.
Claim 11
Dependent Claim
39 words
The apparatus as claimed in claim 2 wherein said mold member includes a welding tool for uniting by welding one portion of a work piece with a second portion thereof seated on a common mandril with the one portion.
Claim 12
Dependent Claim
20 words
The apparatus as claimed in claim 10 wherein said welding tool includes high frequency heating elements in said mold member.
Claim 13
Dependent Claim
29 words
