Title: Disbarking of logs
Inventor: ADAMKO JOZSEF
IPC: B27L1/12
Filed: 1965-09-30
Abstract: 1,045,790. Removing bark. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. Sept. 30, 1965, No. 41655/65. Heading B5L. A method of removing bark from logs comprises beating the log with a flat smooth surface of an implement carried on the free end of a flexible belt secured to a power-driven rotatable shaft arranged parallel with the log, the distance between the log and shaft being such that the implement always strikes the log with its flat surface normal to a radius of the log. In apparatus for carrying out the method, the shaft 1, Figs. 1 and 2 (not shown), is driven by belts from a motor 2 and carries a pair of discs 6 between which are pins 7. Each pin carries one or more, preferably three, belts 8 which are doubled over the pins and riveted to the beating means which are of metal and have a flat beating surface. The log to be debarked is mounted between the centres of wheels 4 of a fixing device 3 movable towards and away from the shaft 1 along inclined ways which may slope downwardly towards or away from the shaft. In operation, the device 3 is moved so that the log is at a position wherein the flat surfaces of the beating means 9 strike the log which is rotatable and movable axially. In another embodiment, the belts 8a, Fig. 4 (not shown), are of a single layer.

A detector coil 1 is connected in series with a current transformer 4 across an alternating supply 3, or compensating or comparison coil 5 being connected in series with a second transformer 6. The secondaries are connected to oppositely connected rectifiers 7 and 8, such that no voltage appears across the terminals 11 and 12 when equal currents flow through the coils 1 and 5. An indicator 13 is connected to terminals 11 and 12 via a filter 14 and condenser 15 such that only changes in the ratio of the currents flowing through transformers 4 and 6 reach the indicator which is thus effected only by vehicles moving in the vicinity of coil 1. The coil 1 may be a single turn coupled over transformer 2.
