An apparatus and method are disclosed for transferring patterns carried by a web of a deformable plastics material onto substrates. The apparatus comprises a nip defined between at least one nip roller and a backing support through which the substrates are passed simultaneously with the web and by means of which pressure is applied to effect transfer of the patterns from the web to the substrates. In the invention, a web heater and a web tensioner are arranged upstream of the nip, and a control unit is provided for controlling the web heater and the web tensioner in dependence upon data indicative of the lengths and widths of the patterns on the web prior to transfer, or of the patterns on the substrates after transfer, so as to ensure that, after transfer to the substrates, the patterns conform to a desired length and width.

Provided is a method for producing a circuit pattern, the method capable of satisfactorily plating a circuit pattern bonded to a release sheet and satisfactorily peeling the plated circuit pattern from the release sheet. The method for producing a circuit pattern includes: a step of plating a predetermined portion on a surface of a metal plate (11); a step of bonding a release sheet (14) to a back surface of the plated metal plate (11); a step of providing a resist pattern (17) covering the plating on the surface of the metal plate (11); and a step of forming a circuit pattern (2) bonded to the release sheet (14) by etching the metal plate (11) provided with the resist pattern (17).
