Paper converting plant including a rewinder adapted to produce paper logs and having an inlet for feeding a paper web, a winding station where the logs are formed and an exit station for unloading the finished logs. The rewinder has walls delimiting a chamber inside which the logs are formed, and an air suction channel at a lower part of chamber. The suction channel exerts a suction causing the formation of an air flow directed from the top to the bottom inside the chamber. The chamber includes two semi-chambers communicating with the air suction channel such that a vertical air flow directed downwards is generated in each of them, the chamber being provided with a manner for regulating the vertical air flows providing vertically oriented identical air flow rates in the semi- chambers.

A perforating apparatus and method includes a longitudinal cylinder axis about which a cylinder rotates. At least one shaped anvil bead is disposed on the cylinder. The cylinder including an anvil block and an anvil bead form a cavity. The cavity may be used to control the debris produced during the perforating process. A blade is disposed on a support to cooperate in contacting relationship with the anvil bead. A web is perforated as the web passes between the rotating cylinder and the support and the blade operatively engages with the anvil bead. The debris may be controlled by being drawn into the cavity prior to the point where the blade engages the anvil and, subsequently, being expelled after the point where the blade engages the anvil bead.

The object of the application is an apparatus (1) for manufacturing of spiral tubes (2) having at least two layers, comprising at least two feeding units (4, 4) for feeding a material strand (10, 10), at least one glue unit (5) for feeding the glue onto the material strand (10, 10), a forming unit (6) comprising a forming rod (13) and a forming strip (14) winding around a formed fragment of a continuous spiral tube (3), and a cutting head (7) for cutting off an individual tube (2) from the continuous spiral tube (3). The apparatus is characterised in that between the forming rod (13) and the cutting head (7) there is situated a cutting unit (8) for cutting the formed or partially formed continuous spiral tube (3) or a scrap section (3A) of the tube. The object of the application is also a method for manufacturing of spiral tubes (2) having at least two layers, in the apparatus (1).

Systems and methods for cutting and cooking a substance are disclosed. Exemplary implementations may: convey, via a primary conveying subsystem, a layer of food substance along a conveyance path; cut, via a cutter, the layer of food substance into food pieces; apply, via a primary pressurized fluid outlet, primary pressurized fluid such that the food pieces are released from the cutter; apply, via a secondary pressurized fluid outlet positioned above the primary conveying substrate and pointed toward the primary conveying substrate, secondary pressurized fluid so that the food pieces are held flat to a primary conveying substrate; heat, via a heating mechanism, air within a chamber to provide an environment suitable for dehydrating the food pieces passing through the chamber; and convey the food pieces for at least a portion of the conveyance path through the chamber and hold the food pieces flat with a secondary conveying subsystem.

A conveyor system 24 carries work items, such as flexible, pliable, food products 22, through a scanning system 28 which generates data pertaining to various physical parameters of the food products. Thereafter, the food products are transported through a processing station which may be in the form of a portioning system 30. Next, the portioned food products are transported to a harvesting system 32 utilizing a actuator 34 to unload the food product portions 36 by vacuuming the portions into a nozzle 90. Such food products are transported to one or more desired locations through a hose/tube connected to a nozzle or may be launched through the air in a trajectory aimed at the desired placement location.

A dust collection system designed for a table saw is disclosed. The dust collection system includes a dust shroud and dust shield to channel dust generated by a blade as it cuts wood or other material. The dust shroud includes fins and walls to peel dust and air off a spinning blade and direct the dust and air downward. The dust shroud encloses the lower front portion of a blade. An insert with a channel into which a dust shield can extend is disclosed.

The disclosure relates to a method and apparatus that separates and efficiently captures from an automated cutting table select pieces of thin, flexible material in an orderly manner which prevents damage to the selected piece while preventing the undesired lifting or movement of the surrounding material. The apparatus comprises a pick head assembly including a cylinder with a plurality of orifices that communicates with the selected piece to maintain contact between the selected piece and the cylindrical surface while the selected piece is being removed.

A rod slicer includes a receiving vessel, a cover vessel, and a rod mount. The rod mount may releasably couple with the cover vessel. At least one blade is mounted to or within the cover vessel. The rod mount has openings for one or more rods. The rod mount can be rotated, causing any rods in the openings to pass across from the rod mount into the cover vessel. In the cover vessel, a slicing edge of the blade, thus cutting a segment of a desired length from the rod. A pump may be connected to an opening in the vessel to vacuum the cut segments into the vessel. In some configurations, the blade is adjustable to change the length of the segments.

A power operated rotary knife assembly including a power operated rotary knife having an annular rotary knife blade, a trim guide, and a drive mechanism for driving the rotary knife blade about an axis of rotation. The assembly also includes a portable power unit, a vacuum assembly and a flexible shaft drive transmission coupled between the power operated rotary knife and the portable power unit. The portable power unit includes a drive motor assembly providing a rotational power source which is operatively coupled to the drive mechanism through the flexible drive transmission to rotate the rotary knife blade. The portable power unit also includes a blower assembly providing vacuum pressure at an inlet duct side, the vacuum assembly being in fluid communication with the inlet duct side to generate a vacuum pressure condition in a region of a cutting opening defined by the rotary knife blade and the trim guide.

A longitudinal cutting device with a cutting mechanism, which is arranged between an infeed and a delivery and has rotary cutters movable transverse to the transport direction, comprises transport devices that are arranged on the knife receptacles of these rotary cutters and bridge the region of the cutting mechanism with a conveying effect.
