Those pesky gripper arms
Am printing coasters, 3.5” round, medium weight from American Coaster.
Gripper bars make an indent into the coaster. Someone said that the Original Heidelberg had rubber pads on one side of the gripper bars. I see no evidence of this. Can anyone confirm same?
Have used electrical tape, to no avail. Now contemplating crafters foam sheeting about 1.5mm thick.
Any suggestions?..The adjustment of the spring in the center of the whirling arms seems to make no difference, nor does adjusting the ball rods attaching the bar to the opening mechanism.
Do you have a C&P? I’d hand feed them.

It’s better to die cut the coasters after printing when your using a Windmill. It’s going to leave a mark or as the saying goes, “thats going to leave a mark”. I’ve run coasters without the lay guides and they printed pretty good, 1 color, can’t depend on accurate registration with two color.
