Flap Wheel and a Method for Producing a Flap Wheel Having a Plate-Shaped Carrier

Abstract

“The invention relates to a method for producing a flap wheel ( 4 ) having a plate-shaped carrier, wherein a plurality of grinding flaps ( 7 ) overlapping in a shingle-like manner are glued to an annular carrier section ( 3, 5 ) that is centered on a rotational axis A of the flap wheel ( 4 ), wherein the carrier section ( 3, 5 ) is produced from an amorphous thermoplastic material, in particular ABS, wherein the surface ( 8 ) of the carrier section ( 3, 5 ) is activated prior to gluing, a heat-curing adhesive is applied to the activated surface ( 8 ) of the carrier section, and the grinding flaps ( 8 ) are placed and pressed onto the carrier section ( 5 ) provided with heat-curing adhesive ( 7 ).”

1 . A method for producing a flap wheel ( 4 ) having a plate-shaped carrier, whereby a number of grinding flaps ( 7 ) overlapping in shingle-like manner are glued onto an annular carrier section ( 3 ,  5 ) centered on an axis of rotation (A) of the flap wheel ( 4 ), whereby the carrier section ( 3 ,  5 ) is produced from an amorphous thermoplastic resin, in particular ABS,
 wherein   the surface ( 6 ) of the carrier section ( 3 ,  5 ) is activated prior to being glued, that a heat-curing adhesive ( 7 ) is applied to the activated surface ( 6 ) of the carrier section, and that the grinding flaps ( 8 ) are placed onto the carrier section ( 5 ) to which heat-curing adhesive ( 7 ) has been applied and pressed onto it.   
     
     
         2 . A method as recited in  claim 1   wherein   the activation of the surface ( 6 ) takes place by slight grinding, partial chemical dissolution or slight etching.   
     
     
         3 . A method as recited in  claim 1 ,
 wherein   the activation of the surface ( 6 ) directly precedes the placement of grinding flaps ( 7 ) on it, and it is thus integrated into the process   
     
     
         4 . A method as recited in  claim 1   wherein   the heat-curing adhesive ( 7 ) is applied to the surface ( 6 ) of a carrier section ( 5 ), that is inclined to the axis of rotation (A) of the carrier ( 1 ) by between 50 and 85 degrees, in particular, between 60 and 80 degrees.   
     
     
         5 . A flap wheel ( 4 ), in particular produced by a method as recited in  claim 1 , having a plate-like carrier ( 1 ) that carries a number of shingle-like overlapping grinding flaps ( 8 ), whereby the grinding flaps ( 8 ) are glued onto a carrier section ( 3 ,  5 ), and whereby the carrier section ( 3 ,  5 ) consists of an amorphous thermoplastic resin, in particular ABS,
 wherein   the grinding flaps ( 8 ) are glued onto the carrier section ( 3 ,  5 ) with a heat-curing adhesive ( 7 ).   
     
     
         6 . A flap wheel ( 4 ) as recited in  claim 5 ,
 wherein   the carrier section ( 5 ) is inclined to the axis of rotation (A) of the carrier ( 1 ) between 50 and 85 degrees, in particular between 60 and 80 degrees.
