Abstract: PURPOSE:To improve the dimensional accuracy between a faceplate and a mesh by raising a cradle behind the rise of a collet chuck at a fixed distance and terminating the fall of the cradle before the collet chuck is let to fall. CONSTITUTION:When a slide axle 20 is pushed up, a collet chuck 26 is pushed upward and is opened. When the slide axle 20 is raised by dimension H, the axle is made to touch a cradle 31 and subsequently the cradle 31 is raised along with the slide axle 20. Then an outer pipe 3 is inserted in the collet chuck 26 and the bottom of the outer tube is made to touch the buffering material 32 of the cradle 31. Subsequently, when the slide axle 20 is withdrawn, the collet chuck 26 is closed and the outer pipe 3 is chucked. The cradle 31 is let to fall along with the buffering material 32 and the pedestral 31 is made to contact the step section 17b of a support 17. The outer pipe 3 is pushed to the cradle 31 through the buffering material 32 and is made to adhere to the cradle 31. As a result, even when a faceplate 1 is pushed using a press head 35, the outer pipe 3 hardly moves downward and the accuracy of the gap dimentions between the faceplate 1 and the mesh 5 is improved.
