Abstract:
An automated floor board texturing cell includes a programmable robot that stores, or has access to, a plurality of patterns. The robot automatically selects a stored pattern for at least one of the floor boards introduced into the cell. The robot textures the floor boards to exhibit the selected pattern. The robot may select a pattern for a batch of floor boards or for each individual floor board. Pattern selection can be random or based on stored information such as a production schedule.
Abstract:
The method of forming timbers especially for use as webs in timber roof trusses comprising feeding timbers in a predetermined path with the timbers extending transversely to the direction of feed and, as the timbers are so fed, shaping the ends thereof to rounded form, and apparatus for carrying out said method comprising conveyors for feeding the work, a saw for cutting the timbers to length, and cutters for the end shaping.
Abstract:
A method of making a base for a split jamb for a door frame opening, with the base having a groove for receiving the tongue of a slide of a split jamb, including the steps of providing an elongate panel, making a plurality of parallel cuts in the panel, with the cuts not cutting through the panel, the cuts including a plurality of pairs of slots, with the slots of a pair spaced from each other leaving panel material between the slots of each pair, adhering a stop strip over each pair of slots covering the slots of the pair, and gang sawing the panel into jamb base strips by cutting between the slots of each pair of slots to remove the panel material between the slots providing individual jamb base strips. The method wherein the step of making parallel cuts includes making a plurality of notches spaced from each other by the pairs of slots, and wherein the step of gang sawing includes cutting through the panel at each of the notches.
Abstract:
A method of manufacturing an elongated braided structural member having high mechanical strength, including the steps of providing at least three primary elongated cores, parallel and spaced from one another, and helically winding a plurality of threads around said cores, at least two threads being wound around any pair of primary cores.
Abstract:
A machine for precision cutting and finishing of curved wooden members, includes a generally vertically disposed column; a support assembly including a plurality of spaced, relatively narrow support guides; a radially adjustable clamping assembly on each of at least two support guides, each clamping assembly having two locking jaws, at least one locking jaw being fluidly operated to move relative to the other locking jaw and for holding and fixing the curved wooden member; an elongated beam rotatably connected at one end to the upper end of the column and cantilevered to extend radially outward therefrom for movement in a circumferential arc over the upper support members, a tool support having one end slidably connected to the elongated cantilevered beam and movable to and fro along the radially extending axis of the beam; a tool holder adjustably connected on the tool support for generally vertical and rotational movement, the tool holder including a T-connector having opposite tool connecting ends and two tool holding rods removably secured in the connecting ends, a cutting saw attachment having a cutting blade mounted on at least one of the tool holding rods; a rack and pinion assembly for moving the tool holder along a vertical axis with respect to the tool support; and a counterbalance weight system connected to the rack and pinion assembly so as to maintain the tool holder at any desired position with respect to the tool support.
Abstract:
The present invention is directed to a unique die (11, 111) that can be employed in apparatus (10) for shaping a workpiece (14, 114) according to the method of driving the workpiece at relatively high speeds through the die (11, 111) which remains fixed. The die has a throat (40, 140) which extends longitudinally through a body portion (35, 135) and opens through a crenelated mouth (45, 145). The mouth is provided with opposed noses (46, 48, 146, 147 and 148) which delineate the distal extent of the mouth with respect to the body portion of the die. Cutting edges (50, 51, 54, 55, 150, 151, 154, 155, 173 and 174) extend rearwardly from the noses, with each pair of adjacent cutting edges joining to define a crotch (59, 60, 159, 178 and 179). The resulting plurality of crotches delineate the longitudinally proximal extent of the mouth with respect to the body portion of the die. Each cutting edges is disposed so that the entering angle .theta. falls within the range of from 25.degree. to 50.degree..
Abstract:
A wood routing machine accepts a length of wood stock, e.g., a length of preformed crown molding, and thereafter in automatic sequence clamps the wood stock at lengthwise spaced locations, routs evenly spaced notches along the length of the stock and after each router operation automatically unclamps and indexes the stock a predetermined distance, again clamps the stock and repeats the router operation sequence until the entire length of stock has been notched to form a length of dental block type wood molding.
