Abstract
Abstract A screen printing machine has a reciprocating printing and feed plate and retractable stops combined and cooperating with said plate so that the material to be printed moves forward over the plate in a stepwise manner. The screen is mounted over this plate and reciprocates with it so that the material passes under the screen. While it is under the screen a relatively stationary printing squeegee is lowered into its operative position and printing is thereby effected.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
In a screen printing machine, in combination, baseplate means having an upper surface and being reciprocable longitudinally in predetermined directions in alternate working and return strokes of predetermined length, so that material to be printed and which may be located on said surface moves with said baseplate means; screen means mounted above said baseplate means for movement toward and away from the upper surface of the same; blocking means associated with said baseplate means and operative during the respective return strokes of the same for blocking material on said surface from moving with said baseplate means, whereby such material advances stepwise over said upper surface and beneath said screen means in one of said predetermined directions; clamping means cooperating with said screen means for clamping the same against said baseplate means when material to be printed is located beneath said screen means; and squeegee means mounted for engagement with said screen means in response to operation of said clamping means to thereby effect printing of material located beneath said screen means.
Claim 2
Dependent Claim
171 words
In a screen printing machine, in combination, baseplate means having an upper surface and being reciprocable longitudinally in predetermined directions in alternate working and return strokes of predetermined length, so that material to be printed and which may be located on said surface moves with said baseplate means; screen means mounted above said baseplate means for movement toward and away from the upper surface of the same; blocking means associated with said baseplate means and operative during the respective return strokes of the same for blocking material on said surface from moving with said baseplate means, whereby such material advances stepwise over said upper surface and beneath said screen means in one of said predetermined directions; clamping means cooperating with said screen means for clamping the same against said baseplate means when material to be printed is located beneath said screen means; and squeegee means mounted for engagement with said screen means in response to operation of said clamping means to thereby effect printing of material located beneath said screen means.
Claim 3
Dependent Claim
24 words
In a machine as defined in claim 1, said blocking means comprising barrier means mounted for displacement in direction normal to said upper surface.
Claim 4
Dependent Claim
29 words
In a machine as defined in claim 1, said blocking means comprising barrier means mounted for displacement in at least substantial parallelism with the plane of said upper surface.
Claim 5
Dependent Claim
65 words
In a machine as defined in claim 1, said blocking means comprising three cooperating barrier elements arranged spaced from one another in longitudinal direction of said baseplate means and being movable in unison with one another relative to said upper surface between a blocking position which they assume during the respective return strokes, and an unblocking position which they assume during the respective working strokes.
Claim 6
Dependent Claim
83 words
In a machine as defined in claim 1, wherein said upper surface is provided with a plurality of slots extending longitudinally thereof; and wherein said blocking means comprises a plurality of projections each registering from below said baseplate means with one of said slots and being movable between a working position in which it is partly located in the associated slot and partly extends upwardly of said upper surface, and a retracted position in which it is entirely withdrawn into the associated slot.
Claim 7
Dependent Claim
32 words
In a machine as defined in claim 1; and support means associated with said baseplate means and operative for supporting material to be printed on said baseplate means in a predetermined position.
Claim 8
Dependent Claim
43 words
In a machine as defined in claim 1, said baseplate means having opposite lateral sides, and said blocking means comprising blocking members located at said opposite lateral sides of said baseplate means and being movable towards one another transversely of said predetermined directions.
Claim 9
Dependent Claim
30 words
In a machine as defined in claim 1; and further comprising guide means for material to be printed and operative so as to guide such material during the advancement thereof.
Claim 10
Dependent Claim
17 words
In a machine as defined in claim 8, said guide means being mounted on said baseplate means.
Claim 11
Dependent Claim
21 words
In a machine as defined in claim 8, wherein said guide means comprises a guide element of substantially prismatic cross-sectional configuration.
