Device and method for producing sheet for abrasive coating and the sheet

An apparatus for producing an abrasive coating sheet, comprising:

• a base;
• a sheet pan placed on said base, said sheet pan having formed therein a groove into which a brazing sheet is fitted;
• a slide member placed on said base so as to be slidable in a longitudinal direction of said sheet pan at a position above said sheet pan;
• a blade slidably disposed in said slide member so as to be brought close to and away from said groove of said sheet pan;
• a height adjusting mechanism for adjusting a height of said blade from said sheet pan by sliding said blade;
• and
• clearance measuring means for measuring a clearance between said sheet pan and said blade.

A method for producing an abrasive coating sheet, comprising the steps of:

• fitting a brazing sheet into a groove of a sheet pan, and holding down said brazing sheet by a sheet hold-down member;
• setting a height of a blade, which is slid along an upper surface of said sheet pan, at a desired position with respect to said upper surface of said sheet pan;
• supplying a predetermined amount of an abrasive coating material onto said brazing sheet;
• and
• sliding said blade at a constant speed along said upper surface of said sheet pan, while keeping the height of said blade relative to said upper surface of said sheet pan at said height position, thereby coating said abrasive coating material onto said brazing sheet.
