Abstract
1,178,032. Moulding chipboard. NIEDERHEINISCHE MASCHINENFABRIK BECRKER & VAN HULLEN. 2 May, 1967 [25 May, 1966], No. 20254/67. Heading B5A. [Also in Division C3] Endless chipboards are produced in a cyclically operating heatable press. An endless belt conveys the chip mat over the pressing table below the ram. The weight of the chip mat in those zones which during pressing are at the transitional region between the pressed board and the still unpressed mat is increased by up to 20% with respect to the rest of the mat. If the board consists of an inner layer of relatively coarse particles and two outer layers of finer particles with a higher glue concentration, the increase in weight may be confined to one or both outer layers; the middle layer may remain constant or may even be reduced in weight at the transitional zones. The three layers may be formed by chips from three hoppers movable to and fro along the direction of travel of the mat, the quantity of chips emerging from each of which being controlled by electric limit switches. German Specification 972,018 is referred to.
