Abstract

An instrument for transferring coating film onto a surface requiring transfer printing. An instrument of this invention for transferring coating film is in such a structure that: a transfer head (4) is composed of a pressing body (4A) having a tape pressing surface (4a) roughly equal in width to the transfer tape (2) and of a pair of right and left side plates (4B) in contact with the transfer tape for controlling widthwise movement of the transfer tape part which is in contact with the tape pressing body (4A); the tape pressing surface (4a) of the tape pressing body (4A) and front edges (4b) of the side plates (4B) are adapted to be continuous or almost continuous in the direction of the width of tape; and each of front edges (4b) of the side plates (4B) is formed tapered so as to gradually depart from an imaginary straight line (X) passing through the tape pressing surface (4a) toward outer sides in the width direction of the tape; whereby the instrument exhibits high transfer printing function and is easy to operate because no damage is inflicted to the surface requiring transfer printing even when the case tilts.

Dependent claims

A paint film transfer device having, mounted in a case (1), an unused tape storage (3) for feedably storing a transfer tape (2) having a transfer paint film (2a) formed on one surface of a backing material (2b), and a transfer head (4) for pressing on the backing material (2b) of the transfer tape (2) fed from the unused tape storage (3) out of the case (1) to transfer the transfer paint film (2a) of the transfer tape (2) to a receiving surface (A),

wherein said transfer head (4) includes a tape presser (4A) having a tape pressing surface (4a) of a width approximately corresponding to a width of said transfer tape (2), and a pair of left and right side plates (4B) for limiting sideways movement of a transfer tape portion contacting the tape presser (4A),
the tape pressing surface (4a) of said tape presser (4A) and tip end surfaces (4b) of said side plates (4B) defining a continuous or nearly continuous surface extending in a direction of width of the tape,
the tip end surfaces (4b) of said side plates (4B) being inclined laterally outwardly of the tape and away from an imaginary straight line (X) extending in the direction of width of the tape through said tape pressing surface (4a).

a feed core (7) on which transfer tape (2) is wound, a takeup core (9) for taking up said transfer tape (2) fed from said feed core (7), and an interlock mechanism (13) having a friction member (10) to rotate said feed core (7) with said takeup core (9), wherein said takeup core (9) has a takeup peripheral speed greater than a feeding peripheral speed of said feed core (7),
with said feed core (7) rotatable relative to said takeup core (9) through slipping between at least one of said friction member (10) and said feed core (7), and said friction member (10) and said takeup core (9),
said friction member (10) being positioned to contact at least one of the opposed surfaces of said feed core (7) and said takeup core (9) linearly in radial directions and in a plurality of positions circumferentially thereof.

A paint film transfer device comprising a transfer tape (2) having a transfer paint film (2a) formed on one surface thereof, a feed core (7) on which said transfer tape (2) is wound in roll form, a transfer head (4) for pressing the transfer tape (2) fed from said feed core (7) on a receiving surface (A) to transfer said paint film (2a) to said receiving surface (A), a takeup core (9) for taking up in roll form the transfer tape (2) having passed through said transfer head (4), and an interlock mechanism (13) for slippably interlocking a rotation of said feed core (7) with a rotation of said takeup core (9) and rotating said takeup core (9) at a takeup speed faster than a feeding speed of said feed core (7),

wherein said transfer head (4) is integrally formed with a shaft member (4c) and is movable in an upstream direction with respect to a direction of tape feeding from said feed core (7) when said transfer head (4) and said transfer tape (2) are pressed upon said receiving surface (A) and said shaft member (4c) slides when said transfer head (4) is moved, whereby the transfer tape (2) becomes unwound while rotating said feed core (7), the transfer tape (2) having passed through said transfer head (4) being taken up on said takeup core (9),
said paint film transfer device further including a rotation stopper (19) movable between a rotation allowing position where said rotation stopper (19) is not engaged with said feed core (7) to allow rotation of said feed core (7) and a rotation stopping position where said rotation stopper (19) is engaged with said feed core (7) to stop rotation of said feed core (7), and an interlock mechanism (25) to move said rotation stopper (19) to the rotation allowing position in response to a pressing operation of said transfer head (4) toward said receiving surface (A) upon start of a transfer operation, and to move said rotation stopper (19) to the rotation stopping position in response to a release operation to release the pressure of the transfer head (4) toward the receiving surface (A).
