Abstract
A method for placing a locking element that forms the spring of a board that is provided with a spring/groove profiling, in particular, a floor panel, in a first groove that is present on one of the lateral edges of the board, where the locking element displays locking means with whose help two boards, connected via the spring/groove, can be locked together laterally with respect to the direction of connection. The method includes transporting the board and locking element at the same speed parallel to each other along a transport distance in a transport direction (T). During the transport, the locking element runs laterally along a fixed device that constantly narrows the transport distance in the direction of transport (T). By means of the device, the locking element is constantly and increasingly shifted laterally with respect to the direction of transport (T) until in the process. Starting with its front end with respect to the direction of transport (T), it is pressed into groove of board in a steadily increasing manner.
