Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
Mechanism for the simultaneous drawing of several strands of metallic stock in continuous casting with at least one independently driven conveying system for each strand, consisting of a conveying roller with its drive shaft on which it is slidably mounted and press roller means mounted opposite to it for sliding movement on a mounting shaft, in which the conveying systems associated with each strand are arranged one behind the other in the direction of the casting and in which the conveying rollers and press rollers of each conveying system are movable in the direction of their shafts to a conveying roller position of each stand, said drive and mounting shafts extending crosswise the several strands.
Claim 2
Dependent Claim
115 words
Mechanism for the simultaneous drawing of several strands of metallic stock in continuous casting with at least one independently driven conveying system for each strand, consisting of a conveying roller with its drive shaft on which it is slidably mounted and press roller means mounted opposite to it for sliding movement on a mounting shaft, in which the conveying systems associated with each strand are arranged one behind the other in the direction of the casting and in which the conveying rollers and press rollers of each conveying system are movable in the direction of their shafts to a conveying roller position of each stand, said drive and mounting shafts extending crosswise the several strands.
Claim 3
Dependent Claim
177 words
A drawing mechanism for the continuous or intermittent drawing of strands of metallic stock in continuous casting having; at least one conveying system for each strand consisting of a conveying roller with its driving shaft and a press roller opposite to the conveying roller and having means for applying a pressure thereto; said conveying roller having independent drive means; said conveying rollers being mounted on driving shafts and arranged in series and spaced from eacH other in the direction of the casting axis; said press rollers and their pressing devices also being arranged in series and spaced from each other in the direction of the casting axis; said conveying rollers being shiftable laterally from one strand to another strand on their drive shafts which extend transverse to the direction of the drawing of the strands; and said press rollers and their pressing devices being mounted on rails extending transverse to the direction of the drawing of the strands and shiftable laterally from one strand to another strand to a position for cooperation with their respective conveying roller.
Claim 4
Dependent Claim
177 words
A drawing mechanism for the continuous or intermittent drawing of strands of metallic stock in continuous casting having; at least one conveying system for each strand consisting of a conveying roller with its driving shaft and a press roller opposite to the conveying roller and having means for applying a pressure thereto; said conveying roller having independent drive means; said conveying rollers being mounted on driving shafts and arranged in series and spaced from eacH other in the direction of the casting axis; said press rollers and their pressing devices also being arranged in series and spaced from each other in the direction of the casting axis; said conveying rollers being shiftable laterally from one strand to another strand on their drive shafts which extend transverse to the direction of the drawing of the strands; and said press rollers and their pressing devices being mounted on rails extending transverse to the direction of the drawing of the strands and shiftable laterally from one strand to another strand to a position for cooperation with their respective conveying roller.
