Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
An apparatus for processing a continuously traveling web comprising, in combination, a drive means to continuously feed said web, and a means positioned downstream of said drive means for receiving said web from said drive means and processing said web into a plurality of pieces, said means comprising, an upper tool carrier, a lower tool carrier, said tool carriers having tools held in parallel and acting in concert to operate on incident material, rocker arms hingedly connected to said tool carrier, adjustable means motively connected to a rocker arm for matching the horizontal velocity of the tools with the velocity of the material to be processed, two crank gears of similar eccentricity arranged in parallel, acting in concert, rotatably connected to a pair of lower rocker arms communicating with the lower tool carrier, and a connecting rod, tensionally and hingedly connecting and synchronizing the horizontal velocities of said tool carriers.
Claim 2
Independent Claim
150 words
An apparatus for processing a continuously traveling web comprising, in combination, a drive means to continuously feed said web, and a means positioned downstream of said drive means for receiving said web from said drive means and processing said web into a plurality of pieces, said means comprising, an upper tool carrier, a lower tool carrier, said tool carriers having tools held in parallel and acting in concert to operate on incident material, rocker arms hingedly connected to said tool carrier, adjustable means motively connected to a rocker arm for matching the horizontal velocity of the tools with the velocity of the material to be processed, two crank gears of similar eccentricity arranged in parallel, acting in concert, rotatably connected to a pair of lower rocker arms communicating with the lower tool carrier, and a connecting rod, tensionally and hingedly connecting and synchronizing the horizontal velocities of said tool carriers.
Claim 3
Dependent Claim
47 words
The apparatus of claim 1, wherein said rocker arms comprise: upper rocker arms having equal length and arranged in parallel and hingedly connected to said upper tool carrier, and lower rocker arms having equal length and arranged in parallel and hingedly connected to said lower tool carrier.
Claim 4
Dependent Claim
46 words
The apparatus of claim 1, wherein said adjustable means comprises a linkage system having a carriage means wherein said carriage means is adjusted by vertical displacement along a lower rocker arm and secured to said lower arm at a point, when motive, approximates a straight line.
Claim 5
Dependent Claim
101 words
A machine for cutting traveling material comprising: an upper knife carrier, a lower knife carrier, said knife carriers having shearing knives, held in parallel and acting in concert to operate on incident material, rocker arms hingedly connected to said knife carriers, adjustable means for matching the horizontal velocity of the shearing knives with the velocity of the material to be processed, two crank gears of similar eccentricity arranged in parallel, acting in concert, rotatably connected to rocker arms communicating with said lower knife carrier, and a connecting rod tensionally and hingedly connecting and synchronizing the horizontal velocities of said knife carriers.
Claim 6
Dependent Claim
101 words
A machine for cutting traveling material comprising: an upper knife carrier, a lower knife carrier, said knife carriers having shearing knives, held in parallel and acting in concert to operate on incident material, rocker arms hingedly connected to said knife carriers, adjustable means for matching the horizontal velocity of the shearing knives with the velocity of the material to be processed, two crank gears of similar eccentricity arranged in parallel, acting in concert, rotatably connected to rocker arms communicating with said lower knife carrier, and a connecting rod tensionally and hingedly connecting and synchronizing the horizontal velocities of said knife carriers.
Claim 7
Dependent Claim
47 words
A machine of claim 4, wherein said rocker arms comprise: upper rocker arms having equal length and arranged in parallel and hingedly connected to said upper knife carrier, and lower rocker arms having equal length and arranged in parallel and hingedly connected to said lower knife carrier.
Claim 8
Dependent Claim
46 words
The machine of claim 5, wherein said adjustable means comprises a linkage system having a carriage means wherein said carriage means is adjusted by vertical displacement along said lower rocker arm and secured to said lower arm at a point when motive approximates a straight line.
Claim 9
Dependent Claim
127 words
A machine for cutting traveling material comprising: a drive means, an upper tool carrier, a lower tool carrier, said tool carriers held motive through said drive means in the direction of traveling material, upper rocker arms hingedly connected to said upper tool carrier, lower rocker arms hingedly connected to said lower tool carrier, adjustable means for control of the horizontal swinging movement of the two tool carriers, and means for processing said traveling material fixedly fastened to said tool carriers, said adjustable means comprises a linkage system having a carriage adjustably secured on said lower rocker arm, said carriage being adjustable by vertical displacement along said lower rocker arm and secured to said lower rocker arm at a point which when in motion approximates a straight line.
Claim 10
Dependent Claim
127 words
A machine for cutting traveling material comprising: a drive means, an upper tool carrier, a lower tool carrier, said tool carriers held motive through said drive means in the direction of traveling material, upper rocker arms hingedly connected to said upper tool carrier, lower rocker arms hingedly connected to said lower tool carrier, adjustable means for control of the horizontal swinging movement of the two tool carriers, and means for processing said traveling material fixedly fastened to said tool carriers, said adjustable means comprises a linkage system having a carriage adjustably secured on said lower rocker arm, said carriage being adjustable by vertical displacement along said lower rocker arm and secured to said lower rocker arm at a point which when in motion approximates a straight line.
