Abstract

Supply system (10) for a silk-screen printing machine comprising a supply table (20) mobile on longitudinal guides (22) in a longitudinal advancing direction (F) of a sheet (12) able to be registered longitudinally through longitudinal registering means (60), the supply system (10) comprising transversal registering means (40) which comprise locking means (50) suitable for locking the sheet (12) on the supply table (20) for a predetermined time and an actuator (24) to move the supply table (20) in a direction transversal to the longitudinal direction (F) such as to allow the registering of the transversal position of the sheet (12) without misaligning it with respect to the longitudinal direction (F).

Claims

1. Supply system (10) for a silk-screen printing machine comprising a supply table (20) which moves on longitudinal guides (22) in a longitudinal advancing direction (F) of a sheet (12), said sheet (12) being able to be registered longitudinally by being passed under longitudinal registering means (60), said supply system (10) comprising transverse registering means (40) which comprise locking means (50) suitable for locking the sheet (12) on the supply table (20) for a predetermined time and an actuator (24) to move the supply table (20) in a direction perpendicular to the longitudinal direction (F) so as to allow the registering of the transverse position of the sheet (12) without misaligning it with respect to the longitudinal direction (F) wherein the transverse registering means (40) comprises a support shaft (30) suitable for supporting the locking means (50) and fixed to the supply table (20) which carries a plurality of supports (31) aligned along it, each of which is fixed to the shaft (30) respectively through an attachment screw (33).

2. Supply system (10) for a silk-screen printing machine according to claim 1, wherein the transverse registering means (40) comprise two transversal guides (28) which couple with each other and are able to slide along the longitudinal guides (22), said supply table (20) being coupled with said transverse guides (28) and being slidable in a direction transverse to the advancing direction of the sheet (12).

3. Supply system (10) for a silk-screen printing machine according to claim 2, wherein the transverse registering means (40) comprise two support shoulders (26) which couple with each other and are able to slide with respect to two longitudinal guides (22), and in which the two transverse guides (28) are respectively housed.

4. Supply system (10) for a silk-screen printing machine according to claim 3, wherein the transverse registering means (40) comprise an optical sensor (40).

6. Supply system (10) for a silk-screen printing machine according to claim 1 wherein the locking means (50) comprise a plurality of pressure elements (51) which can be activated through pressurized air, each of which is respectively housed in one of the supports (31).

7. Supply system (10) for a silk-screen printing machine according to claim 1, wherein the longitudinal registering means (60) comprise retractable stop elements (61) capable of cooperating with the optical sensor (34) to register the longitudinal position of the sheet (12).
