Abstract (en)
[origin: WO0245879A1] The invention relates to a method for transferring a carriage (11, 12) in a sheet metal working machine, wherein a carriage (11, 12) of a moving carriage arrangement in connection with said sheet metal working machine is transferred by means of at least two actuators (16a, 17a; 18a, 19a) parallel in the direction of movement of said carriage (11, 12) controlled by a control value (S) of the position given by a control centre (41), in order to transfer a sheet (14) to be machined and attached to the mounting means (13) of the carriage arrangement, substantially in the main plane of the sheet (14) to perform machining directed to the sheet (14). In accordance with the invention, to prevent twisting caused by asymmetric loading, individual separate measuring values (M16,M17) of the position are determined for the at least two parallel actuators (16a,17a;18a,19a) by means of separate positioning systems (16b,17b;18b,19b) attached in connection with each of said actuators, and each of said separate actuators (16a,17a;18a,19a) is controlled independently and separately by means of difference value between a control value given by the control centre (41) and the measuring value (M16,M17) of the position related to said individual actuator. The invention further relates to an apparatus implementing the method.
