Abstract

A method of screen printing positionally synchronizes a plurality of pallet assemblies on a first screen printing machine with a plurality of pallet assemblies on a second screen printing machine. A screen printed garment having a properly aligned first image received from the first screen printing machine is transferred on a portion of one of the pallet assemblies on the first screen printing machine to one of the plurality of pallet assemblies on the second printing machine. The properly aligned first image on the garment is in proper positional alignment with a screen printing head on the second screen printing machine such that a second image complimentary to the first image is printed on the garment in proper position on the garment relative to the first image without user intervention to positionally locate the first image relative to the screen printing head on the second machine.

First claim

What is claimed is:

1. A pallet assembly for a screen printing machine having an arm and a first alignment indicia, the assembly comprising:
a pallet supporting frame having an upper surface;
an arm-connecting frame mounted to the pallet supporting frame for movement along two transverse axes, an x-axis and a y-axis, the arm-connecting frame having a first rail and a second rail extending in parallel-spaced relationship along the y-axis and each of the first rail and the second rail having a first end and a second end opposed to the first end, a first cross member extends along the x-axis between the first rail and the second rail at the first end and a second cross member extends parallel to the first cross member between the first rail and the second rail at the second end;
a first adjustment mechanism connecting the first cross member to the pallet supporting frame for providing relative movement of the pallet supporting frame and the arm-connecting frame along the two transverse axes; and
a pallet for supporting a textile in a printing operation removably mounted on the pallet supporting frame and having a second alignment indicia.

2. The pallet assembly of claim 1 wherein the first adjustment mechanism comprises a first coordinate adjuster connecting the first cross member to a portion of the pallet supporting frame to move the pallet supporting frame relative to the arm-connecting frame along the x-axis, and a second coordinate adjuster connecting the first cross member to a portion of the pallet supporting frame to move the pallet supporting frame relative to the arm-connecting frame along the y-axis.

3. The pallet assembly of claim 2 further comprising a third coordinate adjuster connecting the second cross member to a portion of the pallet supporting frame to move the pallet supporting frame relative to the arm-connecting frame along the x-axis.

4. The pallet assembly of claim 2 wherein the first coordinate adjuster is attached to the first rail.

5. The pallet assembly of claim 4 wherein the first coordinate adjuster comprises a threaded actuator.

6. The pallet assembly of claim 5 wherein the threaded actuator extends through the first rail.

7. The pallet assembly of claim 4 wherein the first coordinate adjuster further comprises a pin connected to the pallet supporting frame.

8. The pallet assembly of claim 1 wherein the second coordinate adjuster is a threaded rod.

9. The pallet assembly of claim 1 wherein the first cross member is mounted to the arm-connecting frame for movement along the x-axis.

10. The pallet assembly of claim 9 wherein the first cross member is restricted from movement along the y-axis relative to the arm-connecting frame.

11. The pallet assembly of claim 1 further comprising a locking mechanism preventing movement of the pallet supporting frame with respect to the arm-connecting frame when in a first position and permitting movement when in a second position.

12. The pallet assembly of claim 1 further comprising a mechanism for aligning the pallet with the pallet supporting frame.

13. The pallet assembly of claim 12 wherein the mechanism for aligning comprises a pair of a pin and a notch, wherein the pin is positioned in the notch for frictional engagement.

14. The pallet assembly of claim 13 wherein the pin is on the pallet supporting frame and the notch is on the pallet.

15. The pallet assembly of claim 12 wherein the mechanism for aligning comprises three pairs of pins and notches, wherein one of each the pins is positioned in one of each of the notches for frictional engagement.

16. The pallet assembly of claim 15 wherein two of the notches are positioned on one peripheral edge of the pallet and the third notch is positioned on an opposite peripheral edge.

17. The pallet assembly of claim 16 wherein the three pins are positioned on an upper surface of the pallet supporting frame.

18. The pallet assembly of claim 17 further comprising an adjuster mechanism for positioning at least one pin of the three pins.

19. The pallet assembly of claim 17 further comprising an adjuster mechanism associated with each of the three pins.

20. The pallet assembly of claim 19 wherein the adjuster mechanism is a threaded rod.
