Abstract: A cap printing device for printing various logos on the surface of billed caps comprises a lower support structure, with one end of this structure connected to a flat platen. The platen is connected to a guide mechanism which contains a slot, for mounting the cap bill, and a framing bar, for flattening the front panel of a cap and holding it on the platen. The platen is curved so as to alleviate stresses which arise upon flattening. An upper support arm supports a silk screen carrier with removable silk screen frames. The arm is movably connected at the opposite end of the support structure.
