Abstract:
Disclosed are a method of filler taping a screen frame and a method of filling a screen frame. The screen frame is held in such a manner as to be indexable 90 degrees, a tape is attached simultaneously on opposing two sides of the screen frame through linear motion. At the same time, a filling liquid is applied simultaneously on opposing two sides of the screen frame on the rear surface thereof. Subsequently, the screen is rotated 90 degrees, and taping and filling are similarly effected with resepect to the remaining two sides.

Abstract:
The invention concerns an apparatus of chamfering edges of planar plates, particularly of printed wiring boards. According to the invention the plates are stacked in a first step and then chamfered in such a manner that the lower edge of an upper plate and the upper edge of a lower plate are chamfered simultaneously.

Abstract:
The invention concerns a surface grinding apparatus. By means of this apparatus the surface (2a) of a printed wiring board (2) or the like can be grinded. The apparatus comprises a grinding means (4) with an eccentric shaft (12), said grinding means (4) being connected to a brush supporting means (11) and with a grinding stone (15). A brush (10), said brush supporting means (11) and said grinding stone (15) are substantially rectangular in a plan view and driven simultaneously by the eccentric shaft (11). (Fig. 3)
