摘要
A method for sequentially producing lap planks (1) from a continuous extruded member (35) of plastics material comprises forming a tongue (30) on a first end (2) of the lap plank (1) and a groove (32) on the opposite second end (3) of the lap plank (1), so that a plurality of the lap planks (1) can be joined in end-to-end abutting relationship with the tongue (30) of each lap plank engaged in the groove (35) of an adjacent lap plank (1). The tongue (30) of each lap plank (1) is formed by an indent (34) formed in a front surface (6) of the extruded member (35) to form one surface of the tongue (30), and the other surface of the tongue (30) is formed by machining material from the rear surface (5) of the extruded member (35) adjacent the indent (34). In the sequential production of the lap planks (1), the groove (35) is formed in an end (80) of the elongated member (35) from which the just formed lap plank (1) has been severed, and the tongue of that next to be formed lap plank (1) is then formed.
