Abstract
Abstract A succession of tiles are fed on a conveyor towards a printing position in which a plurality of tiles are simultaneously decoratively printed. A first retractable stop arrests the first stop of the succession in the printing position and a second retractable tile engages the last of the tiles to be printed in a single operation and pushes these tiles together against the first stop. A lateral arm presses the tiles to be printed against a lateral guide and the tiles to be printed are lifted from the conveyor against a screen while a printing head presses the screen into contact with the tiles to effect the printing operation. The printed tiles are then conveyed away while the next tiles to be printed are fed to the printing position.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
235 words
A high production machine for decorative printing of tiles or the like, said machine comprising feed means for advancing a succession of tiles, a first stop means having a raised position for arresting the first of the succession of tiles to hold the same in a printing position, and a retracted position out of the path of travel of the tiles after a printing operation, a second stop means movable to a raised position after the passage of at least two tiles therepast for advancing said at least two tiles in the feed direction thereof towards said first stop means, a lateral guide means adjacent one side of the path of travel of said tiles for laterally positioning said tiles in the printing position, means movable towards and away from said lateral guide means to press said at least two tiles thereagainst when the tiles are engaged by said second stop means and arrested by said first stop means, a vertically displaceable frame disposed beneath said at least two tiles in the printing position, pusher means for displacing said frame in synchronization with said first and second stop means to lift the frame and said at least two tiles therewith off said feed means and then to lower said tiles back onto said feed means, and means for decorative printing of said at least two tiles in the raised position thereof off said feed means.
Claim 2
Dependent Claim
235 words
A high production machine for decorative printing of tiles or the like, said machine comprising feed means for advancing a succession of tiles, a first stop means having a raised position for arresting the first of the succession of tiles to hold the same in a printing position, and a retracted position out of the path of travel of the tiles after a printing operation, a second stop means movable to a raised position after the passage of at least two tiles therepast for advancing said at least two tiles in the feed direction thereof towards said first stop means, a lateral guide means adjacent one side of the path of travel of said tiles for laterally positioning said tiles in the printing position, means movable towards and away from said lateral guide means to press said at least two tiles thereagainst when the tiles are engaged by said second stop means and arrested by said first stop means, a vertically displaceable frame disposed beneath said at least two tiles in the printing position, pusher means for displacing said frame in synchronization with said first and second stop means to lift the frame and said at least two tiles therewith off said feed means and then to lower said tiles back onto said feed means, and means for decorative printing of said at least two tiles in the raised position thereof off said feed means.
Claim 3
Dependent Claim
16 words
A machine as claimed in claim 1 wherein said feed means comprises an endless conveyor belt.
Claim 4
Dependent Claim
50 words
A machine as claimed in claim 1 wherein said means to press said at least two tiles against the lateral guide means comprises an arm with a plurality of rollers, one for each of said at least two tiles, each roller pressing against a respective tile in the printing position.
Claim 5
Dependent Claim
29 words
A machine as claimed in claim 1 comprising a cam means coupled to said first and second stop means and the lateral pressing means for synchronizing the operation thereof.
Claim 6
Dependent Claim
58 words
A machine as claimed in claim 4 wherein said cam means comprises a rotatable cam having a plurality of cam surfaces, one controlling said means to press the tiles against the lateral guide means, a second controlling said first stop means, and a third and fourth controlling said second stop means for vertical and horizontal movement thereof respectively.
Claim 7
Dependent Claim
24 words
A machine as claimed in claim 4 comprising means driving said feed means, said cam means and said pusher means from a common source.
Claim 8
Dependent Claim
87 words
A machine as claimed in claim 1 wherein said means for decorative printing of said tiles comprises a screen disposed above said at least two tiles when the latter are positioned by said first and second stop means and said lateral guide means, said at least two tiles being lifted into contact with said screen by said frame during the printing operation, and a vertically reciprocable printing head above said screen for being pressed against said screen to effect a printing a printing operation on the tiles.
Claim 9
Dependent Claim
29 words
A machine as claimed in claim 7 comprising means supporting said screen for manually adjustable vertical movement with respect to said at least two tiles in the printing position.
Claim 10
Dependent Claim
39 words
A machine as claimed in claim 1 comprising means on said frame for entering said path of travel of the tiles when said frame is raised to arrest travel of the successive tiles after said at least two tiles.
Claim 11
Dependent Claim
