Abstract
Abstract Apparatus for treating sheet or continuous ribbon material including a table with idler rolls to support the material to be treated, a drive roll to move the material over the table and vertical guide rolls at an edge of the table. An elongated beam extending across and spaced above the table and a track extending along the length of the beam. Adjustable carrier heads supported on the track for movement along the length of the beam across the table and each carrier head having a bracket to support apparatus for treating the material as the material passes over the table. A drive mechanism independently engageable with each carrier head to individually move that head along the track to position the head along the beam over the table, and a counter and indicator connected with the drive mechanism to measure the distance each head is moved along the track over the table to accurately position each head relative to the table.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
291 words
In apparatus for treating material including a table having idler rolls to support the material, a drive roll to move the material over said idler rolls, vertical rolls at an edge of said table to guide the material as it passes over the idler rolls, an elongated beam extending across and spaced above the table and a track attached to and extending substantially throughout the length of said beam, the improvement comprising a plurality of independently adjustable carrier heads supported on said track for movement along the length of said beam, each of said carrier heads having a bracket attached thereto adapted to support apparatus for treating material as the material passes over said table below said beam, drive means independently engageable with each of said carrier heads to individually move the head with which it is engaged along said track to position said carrier head along said beam over said table, means on each of said carrier heads to engage and disengage said carrier head with said drive means, means operatively connected with said drive means to determine the linear distance each carrier head is moved along said track over said table by said drive means, a carrier head storage section on said beam extending in cantilever relationship past said edge of said table having said vertical rolls, stop means on said beam located adjacent said edge of said table to prevent carrier heads from moving onto the portion of said beam over said table, adjustable means on each of said carrier heads to contact said stop means, and means on each of said carrier heads to release said adjustable means to permit the carrier head to pass said stop means onto the portion of said beam over said table.
Claim 2
Dependent Claim
291 words
In apparatus for treating material including a table having idler rolls to support the material, a drive roll to move the material over said idler rolls, vertical rolls at an edge of said table to guide the material as it passes over the idler rolls, an elongated beam extending across and spaced above the table and a track attached to and extending substantially throughout the length of said beam, the improvement comprising a plurality of independently adjustable carrier heads supported on said track for movement along the length of said beam, each of said carrier heads having a bracket attached thereto adapted to support apparatus for treating material as the material passes over said table below said beam, drive means independently engageable with each of said carrier heads to individually move the head with which it is engaged along said track to position said carrier head along said beam over said table, means on each of said carrier heads to engage and disengage said carrier head with said drive means, means operatively connected with said drive means to determine the linear distance each carrier head is moved along said track over said table by said drive means, a carrier head storage section on said beam extending in cantilever relationship past said edge of said table having said vertical rolls, stop means on said beam located adjacent said edge of said table to prevent carrier heads from moving onto the portion of said beam over said table, adjustable means on each of said carrier heads to contact said stop means, and means on each of said carrier heads to release said adjustable means to permit the carrier head to pass said stop means onto the portion of said beam over said table.
Claim 3
Dependent Claim
74 words
The improvement set forth in claim 1 wherein said drive means is a continuous belt, an idler sheave at one end of said beam, a drive sheave at the other end of said beam, means for rotating said drive sheave, said continuous belt passing around said sheaves and extending substantially parallel to said beam, said drive sheave connected with said means to determine the linear distance each carrier head is moved along said track.
Claim 4
Dependent Claim
116 words
The improvement set forth in claim 2 wherein each of said carrier heads has a first chamber formed therein, said means to engage and disengage said carrier head with said drive means is a piston located in said first chamber, means connecting said first chamber with a source of pressurized fluid, a friction pad on an end of said piston, said belt passing through said first chamber in each of said carrier heads with a surface adjacent said friction pad, whereby application of fluid to said piston moves said piston to force said friction pad into contact with said surface of said belt to move said carrier head along said track when said belt is moved.
Claim 5
Dependent Claim
113 words
The improvement set forth in claim 3 wherein each of said carrier heads has a second chamber formed therein in fluid communication with said first chamber, a second piston in said second chamber located above said adjustable means to contact said adjustable means to release said adjustable means from said stop means, whereby movement of said first piston in said first chamber permits pressurized fluid to flow to said second chamber to move said second piston into contact with said adjustable means to release said adjustable means from said stop means and thereby permit said carrier head to move out of said storage section onto the portion of said beam over said table.
Claim 6
Dependent Claim
128 words
The improvement set forth in claim 1 wherein each of said carrier heads is connected to a source of pressurized fluid, valve means to individually and independently control the passage of pressurized fluid from said source of fluid to each of said carrier heads, each of said carrier heads having a chamber connected with said source of pressurized fluid, a piston in said chamber, a friction pad on an end of said piston, and wherein said drive means is a continuous belt passing through said chamber in each of said carrier heads adjacent said friction pad, whereby passage of pressurized fluid to said chamber moves said piston to force said friction pad into contact with said continuous belt so that movement of said belt moves said carrier head.
Claim 7
Dependent Claim
52 words
The improvement set forth in claim 1 including spring means in said storage section of said beam, one end of said spring means attached to said beam and the other end of said spring means contacting a carrier head in said storage section to urge said carrier head toward said stop means.
