摘要： A device for centering timber blocks or the like when being fed into sawing machines, in which centering means, swingably disposed for working on opposite sides of the blocks, are so coupled that they move from a normal position outwards from each other or inwards towards each other an equal distance, coupling of the centering device being achieved by means of one or more chains, bands or the like which run in opposite directions over chain wheels or the like attached to the centering means, and a spring device which determines the normal position if coupled with at least one of the centering means. The spring device consists of a screw and a nut working in conjunction with it as well as a spring mounted on the screw between the nut and a stop, which screw is given more or less tension by turning of the nut. The screw is connected to an arm mounted on the centering means, through a nut, which is penetrated by the screw. The screw is to be turned in relation to the nut in order to set the starting position of the centering means.
