Abstract
A removable module carrying a screen for a rotary screen printing machine, which stands on four individually vertically adjustable legs, each supported on an individual seating surface mounted on a bedplate. Two screw spindle and movable cylinder-nut mechanisms are provided for in-place angular and transverse position adjustment. The rotational drive of the screen is provided through a slidable Cardan joint.
Claims8
A rotary screen printing machine having a longitudinal axis for the printing of articles in strip form extending in the direction of said axis, said machine comprising a bedplate and at least one removable printing module carried on said bedplate;
- each said printing module comprising:
- a base;
- means for rotatably supporting respective ends of a cylindrical screen, said screen having a screen axis;
- screen-driving means for rotatably driving said screen, said screen-driving means having a module-borne connecting member;
- means for supporting a squeegee-carrier;
- first, second, third and fourth vertical legs mounted in said base for vertical adjustment with respect thereto and each having a lower end, said first and second legs being located on one side of said longitudinal axis of the machine while said third and fourth legs are located on the other side of said axis of the machine;
- and individual means in said base for vertically adjusting each of said legs;
- said machine bedplate comprising:
- even horizontal seating surfaces supporting said lower ends of said legs of said printing module with the said screen axis extending in a direction transverse to said longitudinal axis of the machine;
- guiding means for permanently preventing said first leg located on one side of said machine axis from moving in the direction of said axis of the machine;
- angular adjusting means for horizontally adjusting the position of one of said third and fourth legs with respect to the corresponding said seating surface in a direction parallel with the direction of said longitudinal axis of the machine;
- said guiding means including transverse adjusting means for horizontally adjusting the position of said first leg with respect to the corresponding said seating surface in a direction transverse to said longitudinal axis of the machine;
- and a rotating driving part operatively engageable with said module-borne connecting member for driving said rotary screen.
