Abstract
A mug printing clamping device (20) is shown for transferring images to curved substrates such as the surfaces of a mug (10). The device employs a flexible band (28) which forms a cylindrical cavity lined with a pad (30). A decal (14) containing the image to be transferred is inserted between the pad (30) and the mug (10) and pressure is applied to the flexible band (28) by rotating cam (38) counter clockwise, which moves slidable post (58) in the direction of adjustable post (36). A ratchet gear (40) and pawl (42) lock cam (38) into position enabling mug printing clamping device (20) to accommodate a wide variety of mug sizes. The mug (10) and decal (14) are then heated, causing the sublimation dyes on the decal (14) to transfer the image on the decal (14) to the surface of the mug (10).
Claims11
A mug printing clamping device for transferring an image through the use of heat and pressure from a decal to a mug comprising:
- a flexible band adapted for deformation about a curved surface of the mug, and forming an approximately circular cavity;
- a means for heating the decal and the mug;
- a cam which produces a tension in said flexible band as said cam is rotated, putting pressure in the mug and decal located in said cavity;
- a ratchet and pawl which locks said cam into position;
- said cam, rachet and pawl allowing said clamping device to accommodate a wide variety of mug sizes.
A method of transferring an image to a cylindrical object comprising the steps of:
- selecting a cylindrical object from a group of cylindrical objects having a wide variety of diameters,
- inserting said cylindrical object into an interior cavity formed by a flexible band;
- inserting a decal containing said image between said cylindrical object and said flexible band;
- applying tension to said flexible band by a cam means, wherein said flexible band applies radial pressure on said decal and said cylindrical object;
- locking said can in position by a ratchet and pawl;
- and
- heating said decal and said cylindrical object.
