Abstract: A substrate splitting apparatus and a method for splitting a substrate using the substrate splitting apparatus are provided. The substrate splitting apparatus includes a servo motor, a transmission device, a substrate breaking bar, and a stage. One end of the transmission is directly or indirectly coupled to the servo motor while the other end is coupled with the breaking bar. The stage has a load-lock surface and the load-lock surface faces the breaking bar. The servo motor drives the transmission device to move the breaking bar toward the load-lock surface. A substrate with a pre-crack on the bottom is disposed on the load-lock surface. The servo motor drives the substrate breaking bar to move towards or away from the pre-crack. The method of splitting includes the following steps: forming a pre-crack on the substrate; controlling the servo motor to drive the breaking bar to move towards the substrate; and controlling the breaking bar to press the substrate at the pre-crack.

Abstract: A water jet handler (200) has a loading location (205), a cutting location (210), and an unloading location (215); and two movable mounts (240 and a 245). As a first movable mount (240) receives a molded substrate at the loading location (205), and transports it to the cutting location (210), a second movable mount (245) transports singulated semiconductor packages of a previously singulated molded substrate from the cutting location (210) to the unloading location (215). As the molded substrate on the first movable mount (240) is cut in the X direction (232) by a water jet, the singulated semiconductor packages are unloaded. The molded substrate is then transferred to the second movable mount (245) on which it is cut in the Y direction (272) to produce singulated semiconductor packages, as the first movable mount (240) returns to the loading location (205), when another molded substrate is loaded.

Abstract: An apparatus for cutting dry pasta strands includes a frame and a guide rail mounted to the frame. A bucket is slidably mounted to the guide rail and linearly moves along the guide rail. The bucket has a stepped pasta-receiving channel including a cutting edge. A cutting blade is fixed to the frame for selective sliding engagement against the cutting edge to cut the pasta in half.

Abstract: Tire cutting apparatus comprises first and second tire locating members, a tire cutter on one of the tire locating members and a tire drive. The tire locating members are relatively moveable between a loading position, in which the members are separated to allow location of a tire therebetween and a cutting position, in which the first tire locating member engages an inner surface of a tire and the second tire locating member engages an outer surface of a tire. With the tire locating members in the cutting position the cutter cuts through a portion of the tire between the members and the tire drive effects relative movement of the cutter and the tire to produce a circumferential cut in the tire and thus cut the tire into two separate parts. The cut is preferably located around the tread of the tire such that the two separate halves may be stacked, one inside the other.

Abstract: An apparatus for orienting a check which has attached to it a corroborating paper strip in a manner such that the check and the paper strip are aligned relative to a cutting station to permit the check and the attached strip to be automatically presented to the cutting knife in a precise location such that the knife can automatically cut the check at the location of the intersection of the check edge and the edge of the corroborating paper strip and thereafter separate the two and cause the detached check to be sent to one processing station while the detached corroborating paper strip is sent to a waste paper station.

Abstract: The present invention is an anvil assembly for a slitting machine of the type including an arbor having a plurality of laterally spaced cutting disks mounted thereon. The anvil assembly is mounted to the slitting machine adjacent to the cutting discs. The anvil assembly includes a generally cylindrical core and a plurality of anvil rings which are concentrically disposed about the core under normal unloaded conditions. The anvil rings include an outer cutting surface which is in rolling contact with at least one of the cutting discs on the slitting machine. The anvil rings are resiliently supported in spaced relationship to the core so that when a load is applied to the anvil ring, the anvil ring will move radially with respect to the core independently of the other anvil rings. The resilient support means includes a plurality of support pins extending radially from the core member, and means for biasing the support pins into engagement with the inner bearing surface of the anvil rings.

Abstract: A cutting arrangement for the cutting to shape of a web-shaped material, such as paper webs (2) in printing presses. The arrangement consists of a cutting element (8) and a backing element (3) over which the paper web runs, in conjunction with which one edge of the cutting element (8) is brought intermittently into contact with the paper web for the purpose of cutting through the paper web in its longitudinal sense. The cutting element (8) is so arranged as to change its position intermittently in relation to the paper web (2) between a first, advanced position in which the cutting element (8) uses its edge to cut through the paper web as it passes over the backing element and a second, withdrawn position in relation to the paper web in which the cutting element is not in contact with the paper web. The intermittent movements of the arm between the first and the second position are controlled by a control unit (12) depending on the advance of the paper web (2).

Abstract: Trimmer apparatus for trimming the edge of an endless belt of felt, fabric, or other similar material. The apparatus provides quick-release pins for easy removal of the cutting apparatus from the mounting brackets. The mounting brackets are adjustable in both the vertical and horizontal direction to provide the desired knife orientation. A mounting bracket angle retainer maintains the mounting brackets in a perpendicular relationship to one another while still permitting both folding and adjustment of the mounting brackets.

Abstract: A web slitting apparatus comprises a pair of upper and lower disk shaped web slitting members having their peripheral edges in engagement and disposed for rotation about essentially parallel axes on opposite sides of the web to be slit. The lower web slitting member is driven by a motor having a printed circuit armature. The lower web slitting member and the armature are secured to the motor drive shaft so that when the motor is activated, it directly drives the lower slitting member. The motor is activated only during the initial threading of the winding apparatus to assist in slitting of the web, and during initial acceleration of the web up to the normal line speed, whereupon the motor is deactivated. The web cutting apparatus will thereafter be driven by frictional engagement with the web and continue to slit the web as a web driven slitter.
