Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 161 words
A drive shaft for a slat conveyor having a slat conveyor belt running over the drive shaft and at least one additional shaft, in which the slats on which the cargo is carried are fastened to endless carrier belts spaced apart side-by-side in the direction of conveyance, said carrier belts being equipped on their underside with teeth set transversely to the direction of conveyance and engaging corresponding grooves in at least the drive shaft, comprising the grooves (15) are made in steel plate rings (11) mounted on said drive shaft (2) at least in the area of the carrier belts (5) which steel plate rings are stamped meander-wise corresponding to the division and shape of said teeth (7), and that between the projections (12) defined by adjacent grooves (15) of said steel plate rings (11) and the preferably smooth surface of said shaft (2) molded shapes (13) of an elastomer are mounted, supported pre-loaded on the surface of said shaft (2).
Claim 2
Dependent Claim 161 words
A drive shaft for a slat conveyor having a slat conveyor belt running over the drive shaft and at least one additional shaft, in which the slats on which the cargo is carried are fastened to endless carrier belts spaced apart side-by-side in the direction of conveyance, said carrier belts being equipped on their underside with teeth set transversely to the direction of conveyance and engaging corresponding grooves in at least the drive shaft, comprising the grooves (15) are made in steel plate rings (11) mounted on said drive shaft (2) at least in the area of the carrier belts (5) which steel plate rings are stamped meander-wise corresponding to the division and shape of said teeth (7), and that between the projections (12) defined by adjacent grooves (15) of said steel plate rings (11) and the preferably smooth surface of said shaft (2) molded shapes (13) of an elastomer are mounted, supported pre-loaded on the surface of said shaft (2).
Claim 3
Dependent Claim 28 words
Drive shaft according to claim 1, distinguished by the fact that the molded shapes (12) are self-adhesive at least on the side towards the steel plate ring (11).
Claim 4
Dependent Claim 39 words
Drive shaft according to claim 2, distinguished by the fact that the original material for the steel plate ring (11) is strip steel from which, after stamping, sections can be detached of the length required to form said ring.
Claim 5
Independent Claim 133 words
A method for mounting steel plate rings on the drive shaft of a slat conveyor, said steel plate rings having meander-wise stampings defining transverse grooves and projections corresponding to the division and shape of teeth provided on the underside of a respective slat conveyor belt, comprising inserting elastomer molded shapes into the projections of said steel plate rings, laying said steel plate rings loosely around the smooth surface of said shaft so that the resultant projections at the cut ends of said steel plate ring are adjacent each other, bending the ends of said projections inwardly by 180°, forcing the bent ends together to compress said molded shapes, inserting a clip in a direction axially to said shaft and over said bent ends to hold said bent ends closely adjacent to one another.
Claim 6
Independent Claim 133 words
A method for mounting steel plate rings on the drive shaft of a slat conveyor, said steel plate rings having meander-wise stampings defining transverse grooves and projections corresponding to the division and shape of teeth provided on the underside of a respective slat conveyor belt, comprising inserting elastomer molded shapes into the projections of said steel plate rings, laying said steel plate rings loosely around the smooth surface of said shaft so that the resultant projections at the cut ends of said steel plate ring are adjacent each other, bending the ends of said projections inwardly by 180°, forcing the bent ends together to compress said molded shapes, inserting a clip in a direction axially to said shaft and over said bent ends to hold said bent ends closely adjacent to one another.
