Abstract

709,851. Bending wood. ROTH, W., KERN, A., [trading as FASSFABRIK DIENER & ROTH], and KOLLMANN, F. March 6, 1952 [March 8, 1951], No. 5816/52. Class 145 (2) Solid wood to be bent is heated in a highfrequency alternating electric field, preferably of between 1,000,000 and 10,000,000 cycles per second, until the moisture in the interior of the wood reaches boiling point. The wood may be heated before passing into the bending machine, either while it is stationary or while it is being fed into the machine, or may be heated in the machine, before bending, between suitably formed electrodes. The temperature inside the wood may be measured by thermo-electric means, by a quartz-glass thermometer or by noting the point at which damp patches appearing on the cross-cut parts of the wood begin to steam. Before being heated in the high-frequency field, the wood is dried out so as to have a moisture content suitable to its subsequent use.
