Abstract (en)
The invention concerns a device for crosscutting lengths of timber (15) that are transported at right angles in relation to their lengths of a type comprising a frame (1,3,4) supporting a number of from each other separate cutting and transport units (19) and arranged across the direction of transport of the lengths of wood (15), where each cutting and transport unit comprises an upper part (23) and a lower part (24), means of transport (21), which through relative interaction feeds the lengths of wood in the direction of transport between the upper and the lower parts, means of cutting (20) for cutting the passing lengths of timber. To improve the cutting precision, the means of transport (21) comprises a first and a second continuous running transport element (35,36) that are located one on the top of the other and running parallel with each other, that the first transport element (35) is pivot mounted on and supported by the upper part (23) and that the second transport element (36) is pivot mounted on and supported by the lower part (24), that the continuous running transport elements are positioned by the side of the active cutting part of the means of cutting (20) and that at least one of the transport elements (35,36) comprises an elastomeric friction material in which the lengths of wood are fed forward between the meeting parts (55,40) of the transport elements under the influence of the said friction material.
