Abstract:
1. An apparatus for manufacturing an airbag cover for covering a vehicle airbag, the apparatus forming a linear groove in a work surface of the airbag cover, the groove having a depth falling within the range of the thickness of the airbag cover, the apparatus comprising: a blade for machining the linear groove in the work surface; a transmitting displacement sensor disposed on the opposite side of the work surface of the airbag cover so as to be opposed to a working tip of the blade with the airbag cover interposed therebetween, wherein the working tip of the blade is directly sensed by the transmitting displacement sensor and the transmitting displacement sensor directly senses the distance between the working tip of the blade and a sensor surface of the sensor through the airbag cover; and a control section for controlling the relative position of the working tip with respect to the airbag cover, based on the distance sensed by the transmitting displacement sensor.
