Abstract
Abstract The present apparatus for granulating elongated material includes a transport roller, and infeed and output tables arranged to extend substantially tangentially to the transport roller. A conveyor belt is wrapped around the transport roller and extends from one guide or drive roller adjacent the infeed table and another drive or guide roller adjacent the output table. A tool cooperating with the end of the output table away from the transport roller effects the granulation of the elongated material. The region between the infeed table and the belt is generally funnel shaped. The region between the transport roller and the conveyor belt forms a sheet advance region which extends close to the end of the output table. The portion of the apparatus including the conveyor belt and the input table may be rotated to permit ready access to the end of the output table, which may be formed as a replaceable counter knife.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
235 words
In an apparatus for granulating elongated material including a cutting tool and material feed-in means arranged upstream of said cutting tool between a feed-in point and said cutting tool, as viewed in the direction of feed advance of said material, said feed-in means including at least two rollers and a conveyor belt wrapped around said two rollers, said feed-in means further including a run-off table arranged immediately adjacent to said cutting tool, said run-off table having a downstream end forming a counter edge for said cutting tool, said conveyor belt extending substantially from a feed-in point to said downstream end of said run-off table, the improvement comprising a guide cylinder rotatable about an axis and arranged for cooperation with said conveyor belt, said feed-in means comprising a feed-in table arranged at said feed-in point and extending substantially tangentially relative to said guide cylinder, said run-off table also extending substantially tangentially relative to said guide cylinder, said feed-in table and said run-off table being arranged at an angle relative to each other, one of said two rollers being arranged adjacent to said feed-in table, while the other of said two rollers is arranged adjacent to said downstream end of said run-off table whereby the guide cylinder and the conveyor belt form a guide channel for said material, said feedin means further comprising at least one guide means for said conveyor belt arranged intermediate said two rollers.
Claim 2
Dependent Claim
235 words
In an apparatus for granulating elongated material including a cutting tool and material feed-in means arranged upstream of said cutting tool between a feed-in point and said cutting tool, as viewed in the direction of feed advance of said material, said feed-in means including at least two rollers and a conveyor belt wrapped around said two rollers, said feed-in means further including a run-off table arranged immediately adjacent to said cutting tool, said run-off table having a downstream end forming a counter edge for said cutting tool, said conveyor belt extending substantially from a feed-in point to said downstream end of said run-off table, the improvement comprising a guide cylinder rotatable about an axis and arranged for cooperation with said conveyor belt, said feed-in means comprising a feed-in table arranged at said feed-in point and extending substantially tangentially relative to said guide cylinder, said run-off table also extending substantially tangentially relative to said guide cylinder, said feed-in table and said run-off table being arranged at an angle relative to each other, one of said two rollers being arranged adjacent to said feed-in table, while the other of said two rollers is arranged adjacent to said downstream end of said run-off table whereby the guide cylinder and the conveyor belt form a guide channel for said material, said feedin means further comprising at least one guide means for said conveyor belt arranged intermediate said two rollers.
Claim 3
Dependent Claim
28 words
The apparatus according to claim 1, wherein said feed-in table, said guide cylinder, said one roller of said two rollers and said conveyor belt form a feed-in funnel.
Claim 4
Dependent Claim
45 words
The apparatus of claim 1, comprising a layer of elastic material on the outer surface of said guide cylinder, said layer having such a thickness that variations in thickness of said material to be granulated are compensated by the elasticity of the elastic material layer.
Claim 5
Dependent Claim
89 words
The apparatus of claim 1, further comprising a housing member journaled on said guide cylinder axis for tilting said housing member through a predetermined angle, means for rotatably supporting said two rollers in said housing member, wherein said two rollers are tiltable in unison relative to the guide cylinder by tilting said housing member, at least a portion of said feed-in table forming part of said housing member so as to tilt along with the housing member, and stop means for limiting the angular displacement of said housing member.
Claim 6
Dependent Claim
25 words
The apparatus of claim 4, further comprising switch means operable to permit operation of said apparatus in only one angular position of said housing member.
Claim 7
Dependent Claim
36 words
The apparatus of claim 4, further comprising channel means for receiving granular material cut by said cutting tool, said stop means being positioned to form a locking connection between said housing member and said channel means.
Claim 8
Dependent Claim
22 words
The apparatus of claim 1, wherein said run-off table extends substantially vertically, and said cutting tool is positioned below said run-off table.
Claim 9
Dependent Claim
60 words
The apparatus of claim 1, wherein said feed-in table comprises first and second spaced apart sections, said apparatus further comprising intermeshing knife roller means positioned with their axis extending perpendicularly to the infeed direction of said material to be granulated in the space between said first and second sections, whereby said knife roller means cuts said material into longitudinal strands.
Claim 10
Dependent Claim
35 words
The apparatus according to claim 1, wherein said two rollers are positively driven and wherein the position of said guide means for said conveyor belt is adjustable for adjusting the tension of said conveyor belt.
