    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: 6173748
    Abstract: A method of reducing noise in a barking plant; a barking drum, a chipper and a conveyor between these. The penetration of noise through conveying openings of a partly or wholly covered conveyor (3) for receiving logs from a barking drum (1), and/or a partly or wholly covered conveyor (8′) for feeding logs to a chipper (11), is reduced, and the noise level is decreased by means of the water (21) used for washing the logs. The water forms a continuous curtain (18, 19) at the front and/or back end of the conveyor (3, 8, 8′) between the drum (1) and the chipper (11).

  • Patent number: 6148884
    Abstract: A method of producing a hardwood flooring product, including the steps of processing a strip of raw wood into a blank having a predetermined thickness and width, and top and bottom surfaces defining parallel planes relative to each other, and splitting the blank along the width of the blank from one side to the other to form two low profile flooring strips having the same width as the blank and a thickness less than one-half the thickness of the blank. The splitting step includes the steps of providing first and second circular saw blades mounted on spaced-apart vertical axes for rotation in a single plane intermediate and parallel to the planes of the top and bottom surfaces of the blank and positioning the blank on conveying means upstream from the saw blades with the plane of rotation of the saw blades intermediate and parallel to the planes of the top and bottom surfaces of the blank for movement of the blank from an upstream position to a downstream position relative to the saw blades.

  • Patent number: 6142196
    Abstract: A machine for forming a bottom rail and a valance for a window blind unit. The machine has a support member upon which a length of wood ultimately destined to be a bottom rail or a valance can reside while cutting occurs, and includes at least one laterally movable saw blade for cutting a selectable wood segment at a selectable angle up to Such angular cutting permits a mitred junction of corners in a formed valance. The machine also has at least one wood boring device and at least one wood drilling device to provide for pull cord anchoring whereby cords are passed through a drilled aperture and knotted such that the knot is housed in a bored compartment. The machine can be incorporated and automated for inline inclusion with automated components of a window blind manufacturing and assembly system to provide finished bottom rails and packaged valance components for final installation at a site of use.

  • Patent number: 6098680
    Abstract: A method is used to make bamboo slats which are intended for use in making a blind. The method comprises a first step in which a bamboo stem is split into a plurality strips. The bamboo strips are barked, polished, and bleached before they are adhered side by side to form a base plate. A plurality of base plates are adhered in a stack to form a rectangular bamboo block having bamboo fibers which are arranged in an interlacing manner. The bamboo block is sliced into a plurality of bamboo slat, with each having bamboo fibers which are arranged in the interlacing manner.

  • Patent number: 6062281
    Abstract: A processing system for processing logs having a curvature into lumber pieces. The system has a cutting station including a saw box with a chipper and a vertical arbor saw mounted to the saw box. The saw box is movable upwardly and downwardly and angularly for tilting. The movement of the saw box orients the chipper relative to the log and provides the capability of the saw to follow a curved saw path. A scanner scans the log and a computer processes the scan data to determine the optimum saw path.

  • Patent number: 6039097
    Abstract: A method of position-based integrated motion controlled curve sawing includes the steps of: transporting a curved workpiece in a downstream direction on a transfer, and monitoring position of the workpiece on the transfer, scanning the workpiece through an upstream scanner to measure workpiece profiles in spaced apart array, along a surface of the workpiece and communicating the workpiece profiles to a digital processor, computing by the digital processor, a high order polynomial smoothing curve fitted to the array of workpiece profiles of the curved workpiece, and adjusting the smoothing curve for cutting machine constraints of downstream motion controlled cutting devices to generate an adjusted curve generating unique position cams unique to the workpiece from the adjusted curve for optimized cutting by the cutting devices along a tool path corresponding to the position cams, sequencing the transfer and the workpiece with the cutting devices, and sequencing the unique position cams corresponding to the work

  • Patent number: 5967207
    Abstract: A method of fabricating bamboo slats into bamboo blinds, wherein bamboo wood is cut into bamboo strips of predetermined length. The bamboo strips are polished, then boiled in a hydrogen peroxide solution for bleaching the strips. The bamboo strips are then spliced into raw bamboo slats of a predetermined thickness. Next, the bamboo slats are subjected to grinding. Subsequently the bamboo slats are primed, and then molded by heat pressing. Holes are then punched in the bamboo slats for insertion of a pull cord, so that the finished bamboo slats can be assembled into a Venetian blind.
