A cartridge is configured for slitting a mill roll in a slitting machine. The cartridge includes a first shaft mounted in bearings in a pair of endplates, with one end of the shaft having a driven yoke for rotation thereof. The first shaft includes a row of first circular blades spaced longitudinally by corresponding first spacers. A second shaft is pivotally mounted in the endplates, and is spaced parallel with the first shaft. A dovetail bar is fixedly joined to the second shaft parallel therewith. And, a row of blade holders are mounted along the dovetail bar, with each holder including a second circular blade aligned with a corresponding one of the first blades for cutting in shear a web unwound from the mill roll. The cartridge may be quickly replaced in the slitting machine for each production run thereof for alignment with cores on a corresponding arbor.
Abstract:
A food processing apparatus for slicing food into slices, strips and cubes comprises a frame, a first and second shaft and first, second, third and fourth subsets of blades. The first shaft is coupled to the frame for rotation relative to the frame about a longitudinal axis of the first shaft. The second shaft is coupled to the frame for rotation relative to the frame about a longitudinal axis of the second shaft. The longitudinal axis of the second shaft is disposed substantially parallel to the longitudinal axis of the first shaft and is displaced therefrom. The first and second subsets of blades are mounted to the first shaft. Each blade of the first subset of blades is displaced along the longitudinal axis of the first shaft from adjacent blades of the first subset of blades by a first displacement. Each blade of the second subset of blades is displaced along the longitudinal axis of the first shaft from adjacent blades of the second subset of blades by a second displacement differing from the first displacement. The third and fourth subsets of blades are mounted to the second shaft. Each blade of the third subset of blades is displaced along the longitudinal axis of the second shaft from adjacent blades of the third subset of blades by the first displacement. Each blade of the fourth subset of blades is displaced along the longitudinal axis of the second shaft from adjacent blades of the fourth subset of blades by the second displacement. The first subset of blades cooperate with the third subset of blades to form a first cutting region therebetween for cutting food to a first dimension and the second subset of blades cooperate with the fourth subset of blades to form a second cutting region therebetween for cutting food to a second dimension.
Abstract:
The invention relates to a longitudinal cutting device for cutting out strips (15) in a moving web of material. Said device comprises at least one carriage (5) which is mounted in such a manner that it can be displaced on a guide element (7) which extends transversally in relation to the direction of movement of the web of material. Said device also comprises a support (3, 20) with a freely rotatably mounted upper blade (2). Said device further comprises a drive shaft (8, 29, 39, 46) which extends over the entire width of the machine and which enables the upper blade (2), especially a circular blade, to be driven by means of a gear mechanism. Said upper blade (2) can be operated in a displaceable manner until a toothed wheel (14) which is connected to the circular blade and to the toothed wheel (13, 21) which drives the circular blade (2), is decoupled.
Abstract:
A vertically adjustable web slitter is adapted to be supported by a track of a web-slitting machine, and comprising an input port adapted to receive pressurized fluid. Also, a control assembly is adapted to controllably transmit the pressurized fluid into any one of a set of first fluid passageways. A cylinder is adapted to receive the pressurized fluid from one of the first fluid passageways. A piston, having a first end and a second end, is set into the cylinder and is adapted to be driven within the cylinder by the pressurized fluid. Further, a set of actuators that are adapted to be driven by pressurized fluid are separated by the piston and cylinder from the set of first passageways. Finally, the piston defines at least one second fluid passageway extending from the first end to the second end. A first flexible hose connects each second fluid passageway to a first fluid passageway and a second flexible hose operatively connects each second fluid passageway to one of the actuators.
Abstract:
A web slitting machine for cutting a web or roll of material includes an upper carriage assembly joined to a lower blade holder assembly by a selectively removable guide key which is milled to provide a predetermined cant angle for the blade. The blade is lowered into position by a piston which is rectangular and includes a torsion-resisting sleeve to prevent rotation of the piston about its vertical axis. A pneumatic control provides a plurality of control modes whereby the blade may be raised and lowered with or without locking the upper carriage assesmbly to its transverse bar and vice-versa. A unique side shift adjustment is provided whereby the blade may be shifted to a half-stroke position and the upper carriage locked when the blade is positioned against a lower knife. This ensures that the pressure of the blade against the knife is the pressure exerted at the mid point of the stroke. A parallelogram linkage biased by a spring provides a shock absorber for maintaining blade/knife contact in the presence of webs moving at high speed.
Abstract:
A machine for slitting metal sheet has a bridge-type frame provided with upper and lower beams supported on posts. In the space between the two beams are upper and lower powered arbors and also upper and lower storage arbors which align respectively with the upper and lower powered arbors. Each powered arbor supports and turns several knives which are mounted on hubs along those arbors, and these knives when not needed may be moved, along with their hubs, onto the aligned storage arbors. Each knife is captured in a carriage which moves along one of the beams and contains back-up rollers which bear against the knife to prevent its arbor from deflecting under the spreading force exerted by the metal sheet as it is slit. The hubs have a wide stance, and accordingly the knives on them do not acquire a wobble when the hubs are secured on their respective arbors; yet notwithstanding the wide stance, the knives may be brought quite close together. The storage arbors normally support the ends of the powered arbors, but may be withdrawn to remove the knives from the arbors. The knives are positioned through a lead screw which drives a carriage having stops against which knives on the upper and lower arbors are moved. The carriage may also be provided with fingers that actually capture the knives of a pair and move them to the correct position.
