Providing a cutting area with web-like interleaver material
The invention relates to an apparatus for a single-track or multitrack provision of web-like interleaved sheet material at a cutting region in which products supplied on one track or on multiple tracks are cut into slices and interleaved sheets are introduced which are cut off from the provided interleaved sheet material in the cutting region, having a material store; and having a removal device which is configured for a removal of a material web from the material store, wherein a loop store in which the material web forms a loop is provided for the material web.
Device for Determining and Storing Eccentricity of Customer Roll Within a Slitter winder and Using for Unwinding Control
A measuring device is releasably received within a winding core of a customer roll wound on a slitter-winder (10). The measuring device (20) is releasably fastened within the winding core by fastening element(s) (21) securing the device to the winding core (10) for rotation during winding of the fiber web around the winding core to form the customer roll. Eccentricity of the customer roll as it is wound is determined from movement, speed and/or acceleration data received from at least two sensors of the measuring device and data is stored for use in unwinding the fiber web from the customer roll and serving as control information. Tension variations in unwinding can thus be anticipated and premeditative steps taken to ensure smooth running of the fiber web in unwinding in further processing.
REWIND SYSTEM
A rewind system includes a conveyor assembly and a rewind apparatus. The conveyor assembly is configured to convey strips along a plurality of paths each configured to convey at least one strip. The rewind apparatus includes a drum and a plurality of shafts. The strip on each path is rewound around one of the shafts. Two adjacent shafts do not take up strips simultaneously. The drum is configured to rotate around an axis of the drum. The drum is configured to switch each of the strips on different paths from one shaft onto another shaft after the drum rotates by a predetermined angle.
System of Controlling Performance of a Slitter-winder and/or the Fiber Web Production Line and a Method of Controlling Performance of a Slitter-winder and/or a Fiber Web Production Line
A system (50) for controlling performance of a slitter-winder (25) and/or a fiber web production line (100) has an advisor unit (34, 36, 37) with a processor and a memory including computer program code, configured to cause the advisor unit (34, 36,37) to generate and transmit signals as first control data to the slitter-winder (25) and/or as second control data to the fiber web production line (100) based on information data received from the slitter-winder (25) and the fiber web production line (100) to control performance of the slitter-winder (25) and/or the fiber web production line (100). Performance of a slitter-winder (25) and/or a fiber web production line is controlled by receiving information data from the slitter-winder and the fiber web production line (100), processing the received information data according to a predetermined configuration, based on the processed data; generating signals according to the predetermined configuration to control the performance.
PLANT AND METHOD FOR LASER SCORING
Plant for laser scoring and laminating or vice versa a resealable label on a web material with option to dispense with lamination. The plant comprises: an unwinder station (A) from which a web (11) is fed to a support and guiding a laser station (B1) included in a guided passage of the above-mentioned web (11); a labelling station (B2) included in another guided passage of the above-mentioned web (11), and a slitter-rewinder station (C) to rewind and or slit the web (11) after treatment in the laser station (B1) and in the labelling station (B2), wherein the web (11) of flexible material is selectively driven to pass firstly through the laser station (B1) and then through the labelling station (B2) or the other way around, or to pass only through the laser station (B1).
A method that implements the facility is proposed.
Apparatus and method for making a coil of dunnage
A dunnage conversion system for making a coil of dunnage from a sheet stock includes a coiler, a movable dancer upstream of the coiler and interposed in a path of the sheet stock, and a controller communicatively coupled to each of the coiler and the movable dancer. The coiler is configured to wind the sheet stock, and the controller is configured to control the speed of the coiler based on the position of the movable dancer to control tension of the sheet stock upstream of the coiler. The sheet stock drawn about the movable dancer may be a slit-sheet stock having a plurality of slits configured to expand under tension applied in a feed direction. The controller may be configured to control expansion of the slit-sheet stock upstream of the coiler allowing conversion of the sheet stock into a coil of relatively less dense dunnage prior to or during winding.
Device for determining and storing eccentricity of customer roll within a slitter winder and using for unwinding control
A measuring device is releasably received within a winding core of a customer roll wound on a slitter-winder (10). The measuring device (20) is releasably fastened within the winding core by fastening element(s) (21) securing the device to the winding core (10) for rotation during winding of the fiber web around the winding core to form the customer roll. Eccentricity of the customer roll as it is wound is determined from movement, speed and/or acceleration data received from at least two sensors of the measuring device and data is stored for use in unwinding the fiber web from the customer roll and serving as control information. Tension variations in unwinding can thus be anticipated and premeditative steps taken to ensure smooth running of the fiber web in unwinding in further processing.
Control plan for paper, sheet, and box manufacturing systems
Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. One or more controllers can be used to aggregate orders and information to prepare one or more control plans (e.g., reel maps, reel plans, etc.) for processing a roll of web product through the manufacturing process. The control plan may include a set of instructions for operating one or more systems within the manufacturing process to form the desired finished paper-based product. In such a regard, efficient manufacturing of various paper-based products, including corrugated boxes, folded carton, labels, flexible paper, industrial bags, plates, cups, décor, and many others, can be achieved. Further, efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated.
Longitudinal cutting device
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.
Machine and method for winding strips of web material with means for the transverse cutting of the strips at the end of winding
The machine (1) comprises: —an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N; S); —at least one winding station (15) comprising a winding device (25) and further comprising: guide members for guiding the strip (S) of web material, configured to form at least a loop of web material between a guide roller (43) and a log (B); and a cutting device (61) for transversally cutting the strip (S) of web material in an intermediate position between the log (B) and the guide roller (43), thus generating a tail edge, remaining on the log (B) being formed, and a leading edge, remaining fastened to the guide roller (43).
