Abstract:
A device for forming a groove in a cover, the device including a circular score anvil having a first axis and being rotatable in a first direction and a circular scoring knife having a second axis positioned parallel to the first axis and arranged radially opposite the circular score anvil to define a gap between the score anvil and the scoring knife. The scoring knife is rotatable in a second direction opposite to the first direction and comprises a scoring element having an edge region that is tapered to form a ridge toward a periphery of the element. The edge region includes an intermediate space that divides the edge region into two spaced apart knife edges. A groove is formed in the cover while moving through the gap by operative cooperation of the scoring knife and score anvil.
Abstract:
A cutting machine comprising a chuck table for holding a workpiece, a spindle unit having a rotary spindle for mounting a cutting blade which cuts the workpiece held on the chuck table, and a spindle unit support mechanism for supporting the spindle unit in such a manner that it can move in a cutting direction, wherein the spindle unit support mechanism comprises a movable base, a guide rail which is provided on the movable base and has a predetermined curvature radius, a spindle unit support member which is movably disposed along the guide rail and mounts the spindle unit, and an angle adjustment mechanism for moving the spindle unit support member along the guide rail to adjust the angle.
Abstract:
In a singulation saw for sawing either substrates or wafers there is provided a pair of counter-rotating saw blades mounted for independent movement in a vertical direction for alternately engaging with a first substrate to be singulated. A transport system comprising a pair of substrate carriers reciprocates the first substrate under the pair of saw blades while alternate ones of the saw blades are engaged to cut the substrate. While the first substrate is being cut, the second or other substrate carrier sequentially unloads a cut substrate, loads a new uncut substrate and then moves the uncut substrate to a vision system for determining the position of the substrate relative to the second carrier and then positions the second carrier and its substrate in a standby position ready to be cut by the pair of saw blades that are cutting the first substrate. As the first cut substrate is moved to an unload position, the new uncut substrate is moved into a cutting position; thus, a minimum loss of cutting time is incurred and a minimum amount of cooling water is needed.
Abstract:
A device and method for superficially incising a sausage-like meat product includes a plurality of rotatable cutting elements which are arranged to define a chute therebetween. Each cutting element includes a cylinder and has a circular blade which projects radially from the cylinder. The centers of the respective blades, also located in the cylinder, define a base plane and the blades are all similarly tilted to rotate in tilt planes which are angled from the base plane. In the operation of the device, all cutting elements are simultaneously rotated and a meat product is inserted into the chute. Rotation of the cutting elements simultaneously causes the cylinder to draw the meat product through the chute and causes the blades on the cylinder to superficially cut a helical shaped incision into the meat product. The depth of the cuts are established by the projection of the blades, and the pitch of the helical incisions, can be controlled by the tilting of the cutting elements.
Abstract:
The present invention relates generally to a new apparatus and method for in-situ green sheet slitting. More particularly, the invention encompasses an apparatus and method that uses a modified green sheet slitting machine so that it can provide an in-situ slitting of green sheets that result in a plurality of separate green sheets rolls or strips.
Abstract:
An apparatus for adjusting the mutual distance of several movable elements placed side by side wherein control means are provided to insure that the various movable elements move in a transposition operation, the same distance as determined by measuring means which measure the distance which a first movable element moves. The device includes means for repositioning the relative position of the movable elements such that following the repositioning operation, the various movable elements are maintained at a fixed relative distance from one another, the repositioning being conducted by measuring the distance by which a first movable elements moves and moving the related movable elements in response.
Abstract:
Continuously cast plastic strip has interspaced marks or defects with lengths of unmarked usable strip therebetween. To obtain a maximum possible yield of sheets from such strip, the lengths of the portions between the marks or defects are measured and cut into sheets of two or more different lengths, the cutting being such as to produce the maximum yield of sheets of either or all lengths, singly or in combination, which can be obtained from the length cut. This procedure reduces the loss or waste due to the marks or defects, to a minimum. A special system is provided for this practice and for cutting out the marks or defects between the unmarked strip portions free from defects, with a minimum of loss or waste. Other features are involved.
Abstract:
A machine for puncturing the skins of small pulses, particularly fresh peas which are to be air or freeze dried. The machine has a series of co-axial circular knife blades which are revolved at high speed while the peas are dropped through a gravity feed chute onto the edges of the blades, from which they rebound with their skins nicked by the blades. The feed chute is angularly adjustable relative to the blades to allow for variations in the size and quality of the peas or other pulses requiring slitting.
Abstract:
A sausage slicing apparatus which includes a conveyor for horizontally moving an elongated package of sausage in a horizontal direction while supporting the sausage in a cradle. A plurality of banks of rotary driven, disk-shaped cutter blades which are horizontally offset or staggered to sequentially engage the sausage package are provided in a position to cut through portions of the sausage package in sequence, with minimum power required to effect complete cutting of the entire sausage package into patties or sausage disks. Stripper fingers are provided and extend between adjacent disk-shaped cutter blades of the apparatus for preventing the adherence to the blades of fatty materials from the sausage, and consequent plugging of the blades and an increase in power requirements of the apparatus.
