<p>PCT No. PCT/SE96/00378 Sec. 371 Date Oct. 24, 1997 Sec. 102(e) Date Oct. 24, 1997 PCT Filed Mar. 26, 1996 PCT Pub. No. WO96/33849 PCT Pub. Date Oct. 31, 1996A machine for producing a wooden element made up of parallel rows of bars comprises a tape-applying device intended for such application of a strip of adhesive tape on pairs of adjacent rows in parallel therewith that the strip of adhesive tape joins the rows together, as well as a cutting device intended to cut the material web made up of the thus-joined bar rows into predetermined lengths. The cutting device has a reciprocatingly movable carriage provided with a rear cutting unit and a front stop element, the distance between the latter being adjustable according to the aimed-at cutting length. When fed forwards, the material web impinges upon the stop element, thereby to displace the carriage from an initial position to a turning position. The cutting unit performs a cutting operation during this displacement of the carriage. Before the carriage reaches its turning position, the stop element is removed in order to release the cut-off length of material web, thus enabling it to be discharged from the machine. A discharge conveyor discharges the cut-off length of material web at a speed exceeding that at which the material web is fed in the remainder of the machine. A return element returns the carriage to its initial position.</p> |
