Apparatus for registering a work support pallet on a printing machine arm with a screen frame, comprising:
- a pallet tool,
- a first pair of pivot rods pivotally disposed in spaced relation on both the pallet tool and on said arm adapted to effect accurate movement of the pallet tool relative to said arm and into proximity with the work support pallet and the screen frame, and
- cooperating registration features on the pallet tool and on the screen frame for registration therebetween to secure the pallet tool in registration with the screen frame.
Apparatus for registering work support pallets on extending arms of a carousel printing machine with successive screen frames of the machine for imprinting registering images on workpieces on the work support pallets, said apparatus comprising:
- a work support pallet disposed on and aligned with an arm of the machine and adapted for registration with a screen frame of the printing machine,
- a pallet tool adapted to underlie the work support pallet, and
- at least one pair of pivot rods having lower portions pivotally mounted in spaced relation on the pallet tool and their opposite upper portions pivotally mounted in spaced relation relative to the arm,
- whereby the pallet tool is accurately swingable between a retracted position and a service position wherein the pallet tool is disposed beneath the screen frame for registration therewith of the work support pallet, and
- cooperating registration features on the pallet tool and on the screen frame for registering the work support pallet with the screen frame.
