Abstract

A hold-down pallet for a textile printer, the pallet comprising a central board and flaps, the flaps moving between an open position to allow placing of a garment and a closed position to hold a garment firmly on the board for printing, the pallet travelling between a garment setting position and a printing area and comprising an engagement mechanism which engages the pallet as it enters the garment setting position. Engagement opens the flaps so that the flaps are in the open position in the garment setting area, the pallet disengaging to close the flaps as it heads for the printing area.

First claim

What is claimed is:

1. A hold-down pallet for a textile printer, the hold-down pallet comprising a central board and flaps, the central board having an upper face, the flaps able to alternate between an open position to allow placing of a garment and a closed position to hold a garment firmly on the central board for printing, the closed position defining a narrow gap between each flap and said central board to tightly retain said garment, the hold-down pallet travelling between a garment setting position and a printing area and comprising a closing mechanism configured to place the flaps in the closed position prior to entering the printing area, the flaps in the open position extending upwardly above said upper face, and in the closed position being flush with said upper face.

2. The hold down pallet of claim 1 , wherein said closing mechanism is configured to place the flaps in the open position when entering the garment setting position.

3. The hold-down pallet of claim 1 , wherein said closing mechanism comprises an engagement device for engaging a lever of said pallet, said lever acting on said flaps to rotate said flaps between said open position and said closed position upon engagement and upon disengagement.

4. The hold-down pallet of claim 3 , wherein said flaps comprises at least three flaps on at least three sides of said central board, each flap being connected to open upon engagement with said engagement device and to close upon disengagement with said engagement device.

5. The hold-down pallet of claim 4 , wherein a fourth side of said central board is left open.

6. The hold-down pallet of claim 4 , wherein said flaps are rotated into said closed position by pivoting towards said central board.

7. The hold-down pallet of claim 6 , wherein said flaps fall short of said central board in said closed position, leaving finite gaps on respective ones of said three sides between a closed flap inner end and said central board.

8. The hold-down pallet of claim 7 , wherein said flaps rotate downwardly from respective sides into said upper face of said central board so that oppositely facing flaps rotate in opposing directions respectively, thereby to pull said garment tightly into said gap.

9. A hold-down pallet for a garment printer, for printing garments, the garments having edges, the hold-down pallet comprising a board and flaps, the board having an upper face, the flaps forming elements on at least three sides of the board to hold a respective garment by its corresponding edges taut against the upper face of said board, the flaps mechanically connected to open and close together, said flaps in an open position extending upwardly of said upper face of said board, said flaps in a closed position being flush with said board and defining a narrow gap with said board, the gap being defined for a garment thickness, thereby to hold said garment firmly against said board.

10. The hold down pallet of claim 9 , wherein the flaps are mechanically connected to open and close according to a current position of the hold-down pallet relative to printing areas of said printer and a garment setting location.

11. The hold-down pallet of claim 10 , comprising three of said flaps on three sides of said board, with a fourth side of said board left open.

12. The hold-down pallet of claim 11 , wherein said flaps close into said closed position by pivoting downwardly towards said board to pull said garment taut.

13. A hold-down pallet for a textile printer, the hold-down pallet comprising a central board and flaps, the central board having an upper face, the flaps able to alternate between an open position to allow placing of a garment and a closed position to hold a garment firmly on the central board for printing, the closed position defining a narrow gap between each flap and said central board to tightly retain said garment, the hold-down pallet travelling between a garment setting position and a printing area and comprising a closing mechanism configured to place the flaps in the closed position prior to entering the printing area, wherein said flaps rotate downwardly from respective sides into said upper face of said central board so that oppositely facing flaps rotate in opposing directions respectively, thereby to pull said garment tightly into said gap.
