Abstract: Stitch bonded fabrics suitable to be used as backings for flexible coated abrasives with facile straight tear in either the length or cross directions have (1) an areal density between 51 and 153 gm/m<2>, (2) a tensile strength in the length direction between 5.4 and 12.6 kN/m of width, (3) a tensile strength in the cross direction which is between 5.4 and 11.7 kN/m of length and is between 0.9 and 1.35 times as great as the length direction tensile strength, (4) an elongation to break in the length direction of not more than 40%, and (5) an elongation to break in the cross direction of not more than 35%. To make the coated abrasives, the fabric is prepared for coating by saturation with at least its own weight of a finishing adhesive composed primarily of latices of acrylic homopolymers, acrylic copolymers, butadiene-styrene polymers, or mixtures of these types. Conventional making, grit coating, and sizing are then performed to yield a coated abrasive with a ratio of length direction tensile modulus to cross direction tensile modulus within the range of 0.8 to 1.8.

Through holes 37, 39 are formed at the same positions on the frame bodies 31, 33, and an inflow port 38 communicated to the hole 37 is formed on the frame body 31. A notch 35 is formed at the portion of the plate 32 where the inflow port 38 is located when both frame bodies are overlapped. The electrolyte flowing through the holes 37, 39 passes the inflow port 38 and is guided to the cell interior through the notch 35. Accordingly, even if the thickness of the conductive plate is made thin, it is firmly supported by the frame bodies, and an increase of weight can be prevented.
