FIELD: woodworking industry.
SUBSTANCE: device to check the parallelism of a setting scale to the axis of a lower front roller at a gangsaw comprises a horizontal support with a vertical stopper which are resting against a journal of the front feeding roller, a block level for control position identification and a vertical pole. The vertical pole is fitted with a support bar, an indicator, an adjustment screw and a support bar to rest against the setting scale. The support bar of the vertical pole directly rests against the setting scale and serves as a support for the adjustment screw with the position of the latter being measured by the indicator. The deviation of the setting scale from the parallelism is determined basing on the difference of two measurements of the scale position in relation to the roller journals by a measuring device. The measuring device is rested against two points - the roller journal and the setting scale surface. The measuring device is set in the control position as per the level with the help of the adjustment screw. The adjustment screw rests against the setting scale surface through the support bar which is pivotally coupled to the horizontal support. The level is used to identify the control position of the device. The deviation of the setting scale is measured by the indicator.
EFFECT: reduced labour inputs in measurements.
