  • Patent number: 10369821
    Abstract: In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.

  • Patent number: 9039002
    Abstract: A sheet post-processing apparatus which is capable of shortening time wasted until actual start of punching and enhancing productivity. A drive unit causes a moving member which has a cam and reciprocates. A punching member is driven by a movement of the cam of the moving member and punches a sheet when the moving member moves forth and moves back. A determination unit determines a type of the sheet. A control unit controls, when a sheet to be punched is to be subjected to a punching process, the drive unit such that the moving member starts moving before conveyance of the sheet to be punched stops, and controls, when the sheet to be punched is to be subjected to the punching process, the drive unit such that timing with which the moving member starts moving is changed based on the determination by the determination unit.

  • Patent number: 8881628
    Abstract: A carpet recycling machine includes a carpet-pile removal machine and a carpet-thickness identification means. The carpet-thickness identification means is incorporated in a carpet handling system that includes a conveyor. In use, carpet is placed pile down on one end of the conveyor which feeds the carpet in to the carpet-pile removal machine. The carpet is urged to pass the carpet-thickness identification means, which measures the thickness of the carpet's backing substrate. This measurement is used to control an offset setting means of the carpet-pile removal machine in order to set an offset between a blade and first roller. Thus the height that the blade cuts the carpet can be set for each piece of carpet processed. As the carpet continues past the carpet-thickness identification means, towards the carpet-pile removal machine, the carpet is urged into the carpet-pile removal machine to be separated in to pile and backing substrate.

  • Publication number: 20130276602
    Abstract: Traditionally, in order to avoid interfering with a work-piece such as a round material and an hexagonal material etc., an insert plate used as a saw blade side support of a band saw machine or a circular saw machine is provided at a position apart from the cutting site after passing the maximum cutting width, which results in the bending, vibration and noise of the saw blade, thereby decreasing the life of the saw blade. This problem is solved with two insert plates located at two positions on left and right of a work-piece to support the saw blade in a manner of moving them closing to the work-piece along the external shape of the work-piece from the cutting start and after passing the maximum cutting width by enabling them to move along the external side of the work-piece, therefore, one side of the insert plates takes a tapered shape so as to get into under the work-piece.

  • Patent number: 7055418
    Abstract: A device for trimming and automatically cutting of either multiple or single images, the images produced for example through digital rendering on paper and other graphic and photographic substrates, wound in reel or being in single sheets (10), especially of large size. Problems in using known devices of this type with feeding rollers (2) with a length corresponding to the substrate width have the consequence of a slowing down of the production owing to the excessive care necessary when introducing at the same time parallel sheets of large size. These problems can be overcome by using rollers of reduced length, but only by adding errors in the forward movement of the substrate, errors which are remedied by of optical sensors (4, 4?) for detecting the separation mark (M) between the images (10a, 10b, . . . ) as well as its angle with respect to the cutting line (7), and by a pair of length differential measuring devices (6).

  • Patent number: 7040204
    Abstract: A method for preparing a graphic on a sheet of material which also includes at least one registration mark at and about the graphic in predetermined positions. The method involves the steps of applying the graphic and at least one registration mark on a sheet of material in positions according to layout data, transferring the layout data to a processing controller, placing the sheet of material on a sheet-receiving surface, sensing the position of the registration mark on the sheet of material, and utilizing the layout data and the position of the registration mark to precisely narrow-path-process around the graphic on the sheet of material. Certain embodiments use either (a) a subset of marks which is applied on one side of graphic or certain reference features, such as edges and corners of the sheet and elements of the graphic, to ascertain the position and orientation of the sheet on the apparatus.

  • Patent number: 7036411
    Abstract: An active measurement and control system for a material cutting apparatus. The apparatus comprises a cutting tool which may be pivoted for cutting a workpiece in a cutting area at a selectable angle. The cutting area defines a datum plane, and a feed table with a shuttle vise is used to move the workpiece toward the cutting area. A controller controls the feed distance of the shuttle vise and the cutting angle of the tool in response to a signal from a sensor used for sensing a transverse dimension of the workpiece relative to the datum plane. In this way, the feed distance and cutting angle are adjusted to compensate for variations in the transverse dimension. This transverse dimension can include a displacement from the datum plane of a distal and/or proximate surface of the workpiece. A method of cutting a workpiece is also disclosed.

  • Patent number: 6978925
    Abstract: A method for creating multiple punch holes during a finishing process of paper sheets and other sheet materials. A highlight of the present invention is the ability to select between at least two configurations of punch holes automatically, without manual adjustment, and “on-the-fly” without interruption of the sheet or paper flow. The perforation method utilizes two rotatable punches set at different angles such that when one intersects the sheet path, the other clears the sheet path. The speed of rotation is controlled such that the non-selected punch intersects the sheet path in a space between pitches.

  • Patent number: 6971423
    Abstract: A log handling and cutting system which cuts logs into lengths, and allows for maximum use of fiber. The system includes equipment for singulating the logs, optimally removing the bark from the logs, scanning the true log image, cutting the logs to length, and sorting the cut logs arranged in a sequence of coupled operations. The logs are singulated using a dual quadrant singulation system to provide maximum singulation reliability, thereby allowing a single operator to attend to this process. Once singulated, the logs are fed automatically into a debarker where the diameter and volume are scanned and debarker-operating parameters are set for optimum bark removal. The log is then scanned, tree length, using a unique scanning system, which determines the true image of the log. This enables the determination by computer of the optimum bucking solution of the log as well as a proper sorting of the optimum random lengths.

  • Patent number: 6895843
    Abstract: A resaw apparatus and method of sawing a succession of boards from a cant of a succession of cants. A band saw is vertically positioned to cut the succession of boards from the cant as the cant is reciprocated through the saw. A pivoted raker gate downstream of the band saw's blade engages the cut board and prevents it from passing through the saw in the reverse direction. A vertically movable live hold-down roller upstream of the saw blade presses down on the cant during sawing. A measuring device measures the cant's height prior to sawing the first board from the cant. When the raker gate moves into its vertical position after the cut board passes, the saw blade is raised slightly to avoid contact with cant splinters on the reverse pass. Each cant is processed to completion before sawing the next cant.
