摘要:
A device for the elimination of trimmings of rolls or logs of ribbon-like material associated downstream with a shearing machine of at least one roll or log (11), fed by a feeding plane (13) of rolls (10) and head and/or tail rolls (24), consecutively. The device comprises a conveyor group (14) for carrying the rolls (10) and eliminating the head and/or tail rolls (24,24′), wherein the feeding plane (13) comprises rests (15) and the conveyor group (14) comprises flaps (21), both shaped, facing each other and spaced between each other to define central longitudinal openings (16 and 22) for the passage of pushers (17) which allow at least one roll or log (11) to advance; the conveyor group (14) having chains (20) on which flaps (21) are positioned, and having a length of chains (20) without flaps (21) that define a movable opening (23) between adjacent chains.

A device for three-sided trimming of products has a cutter lifting assembly that is operable in a lifting movement that determines a machine cycle of the device. Several cutters, at least for head trimming, foot trimming, and front edge trimming of the products, are mountable on the cutter lifting assembly. The device has a lateral alignment configuration, which is movable at least on one side, for performing a pushing movement against the product, by way of which the product can be brought into a cutting position. The device further includes a device for initiating and/or terminating the pushing movement of the alignment configuration in such a way that the time of initiation and/or the pushing duration of the pushing movement within the cycle duration of the device is independent of the lifting movement of the cutter lifting assembly.

In a system for cutting glass sheets into shapes there is at least one cutting site (A, B). In order to align the glass sheet which is to be cut or the glass sheet shape into a defined position, on the edge of the tables I and II there are contact edges (21, 44, 45). In order to move the glass sheets and the glass sheet shapes into contact with the contact edges (21, 44, 45) the tables I, II are aligned sloping down toward the contact edges (21, 44, 45) so that the glass sheets and glass sheet shapes slide on air cushions produced between the glass sheets or glass sheet shapes and the tables (I, II) in contact with the contact edges (21, 44, 45). The glass sheets or glass sheet shapes which adjoin the contact edges (21, 45) are coupled by force-fit to the conveyor belts (20) which are provided in the area of the contact edges (21, 45) and then moved to the cutting site (A, B) which is located following the table (I, II). When there are two cutting sites (A, B) the table (11) can be inclined between the two cutting sites (A, B) such that the intersection point which is used as the reference point (43) between the two contact edges (44, 45) is the lowest point of the table (II).
摘要:
An apparatus and method for removing trim from logs of sheet material. In some embodiments, the apparatus has a first axle defining a first axis, a second axle defining a second axis, a first guide assembly, a second guide assembly, a conveyor extending across the first and second axles and through the first and second guide assemblies so that the first guide assembly and the first axle define a first section of the conveyor, the second guide assembly and the second axle define a second section of the conveyor, and the first guide assembly and the second guide assembly define a third section of the conveyor below the second section. One or both of the first and second guide assemblies are preferably movable to discharge trim from the apparatus. In some embodiments, the conveyor includes first and second endless members.

Diagnostic strips of the kind which are exposed to biological fluids such as blood or urine to detect or monitor medical conditions are cut sequentially from elongated cards by a reciprocating shear blade. The cards may be ones which exhibit defective areas that should not be included in the finished strips. Blade motion seats each newly cut strip on a movable strip carrier which abuts the blade during the cutting operation. The carrier then travels a nondefective strip to a pickup location where it is precisely positioned and picked off of the carrier for emplacement in a housing. A strip with a defective area is carried further to a discharge location where it is released into a waste receptacle. This enables more economical manufacture of diagnostic strips by efficiently making use of nondefective areas of cards that have defective areas.

A cutting apparatus cuts a rolled dough product. The apparatus includes a conveyor conveying a rolled dough cylinder along a dough travel path. A nozzle is coupled to a liquid source providing liquid under pressure and is directed toward the dough travel path. The nozzle is offset from a surface of the dough cylinder by an offset distance sufficient so the cutter can cut a portion from the dough cylinder and provide sufficient separation between the cut portion and the dough cylinder so the cut portion does not stick to the dough cylinder.

A bacon slicing system (10) includes a conveying system (20). The conveying system (20) is mounted for sliding between a first and second lateral position. The conveyor belt (65) of the conveying system (20) is rotatable in a longitudinal direction which is generally perpendicular to the lateral movement of the conveying system (20).

A cigarette manufacturing machine having a shaving device for shaving a bead of tobacco fed along a given path, wherein two tubular shaving bodies, arranged eccentrically one inside the other and having respective serrated annular end edges having a tangent portion located along the path of the bead, are rotated at different angular speeds about axes substantially parallel to the path to shave the bead; the inner tubular shaving body communicating pneumatically with a suction device.
摘要:
A continuous strip of sheet paper material is divided into blanks by a device comprising a cutter and an anvil rendered capable of sliding movement one in relation to the other and establishing a cutting position toward which the strip is advanced by way of a passage incorporated into the anvil; the cutter is reciprocated across the anvil in such a manner as to pass through the cutting position transversely to the strip, alternating between two limit positions on opposite sides of the passage, the geometry being such that the cutter will vacate the passage entirely when occupying either one of the two limit positions.
