Abstract

A workpiece to which a transfer pattern is to be applied is formed to have a rod-like element curved into a loop-like shape to form an apparent geometric plane. A transfer film used in the liquid pressure transfer is formed on a required portion thereof, and the transfer pattern for decoration is formed to have a configuration corresponding to that of the apparent plane. The workpiece is handled so as to downwardly approach the transfer film from a position corresponding to the transfer pattern, and is then immersed in the transfer liquid. Consequently, the transfer film bonds to the rod-like element of the workpiece so as to circumferentially surround the rod-like element continuously from a bottom of the rod-like element to a top thereof on the basis of a diametric section of the rod-like element. Thus, the transfer pattern is transferred to at least the rod-like element of the workpiece.

Dependent claims

A liquid pressure transfer method comprising:

supporting a transfer film on a surface of a transfer liquid while floating the transfer film on the surface, the transfer film having a transfer pattern for decoration printed only on an area of the transfer film having a shape corresponding to a surface shape of a workpiece to be covered by the transfer pattern so that the transfer pattern has a pattern configuration;
handling the workpiece so that the workpiece approaches the transfer film from a position above the transfer pattern;
and
immersing the workpiece in the transfer liquid so as to transfer the transfer pattern onto a surface of the workpiece so as to decorate the workpiece, the workpiece including a rod-shaped element curved to form a loop in a geometric plane, the transfer pattern being printed on the transfer film such that the pattern configuration of the transfer pattern corresponds to a configuration of the workpiece;
wherein said transferring of the transfer pattern to the surface of the workpiece comprises bonding the transfer film to the rod-shaped element of the workpiece so that the transfer film circumferentially surrounds the rod-shaped element continuously from a bottom of the rod-shaped element to a top of the rod-shaped element with respect to a diametric cross-section of the rod-shaped element.
