A simple yet complete device to compare molding mitered angles & lengths commonly used in, but not limited to, the picture framing industry. This device will take pair lengths of molding placed bottom surface to bottom surface with the outer surfaces of the moldings located and centered by means of a 2 toned pattern on a plate, with the mitered surfaces abutted against a radiused tab at one end of the plate. After centering & pushing the moldings against the radiused tab the user rubs a finger across the front end (near tab contact point) of the molding miter & at the opposite end of the molding miter. It will be very evident if the molding miter angles, and, or, the molding lengths are not the same; as any high points or steps, as small as a few thousandths of an inch can be sensed by a finger passing across abutting sharp edged surfaces.

A method for bending a sheet of wood with a plastic laminate applied to its outside face to form a rounded corner on the sheet includes first making a cut across the sheet which is configured to completely wrap around a dowel when the sheet is bent to the desired angle. The laminate is heated prior to bending if heating is required to make it bendable. Adhesive is applied to the dowel, and the dowel is placed on the cutout. The sheet is then bent around the dowel and is held in place until the adhesive has cured and the laminate cooled down. An apparatus attaches to both portions of the sheet and causes it to be bent around the dowel without causing the laminate to stretch or contract.

A machine for forming a formation in a sheet of material. The machine has a pair of upper and lower rollers which are driven rotatably by a motor. A single, stationary cutting bar is provided in an off-set position with respect to a center line of a rectangular opening in the frame of the machine. A blade assembly is laterally mounted to the frame across the rectangular opening. As the blade assembly is moved laterally closer to the cutting bar, the blade assembly produces a deeper cut into a sheet of material passing between the upper and lower rollers than if the blade assembly had not been moved laterally or had been moved laterally away from the cutting bar which would have produced a more shallow cut or a cut with less depth.

A combination simple and compound mitre gauge along with a precision split fence constitute the subject matter of the present invention. Both the mitre gauge and fence are intended to be utilized with power woodworking tools. The mitre gauge constitutes both a simple and compound gauge by utilizing an elongated member which slides in a groove on the supporting table and a suppport plate coupled with the member which is movable about a vertical axis and can be held in a given position by appropriate locking means. The support plate presents a vertical surface which mounts a guide that can be moved into one of two positions to vary the length of it. The guide may also be removed and a planar surface presenting shoe pivotally coupled with the support plate. The angle of the planar surface of the shoe may be varied and means is provided for locking the shoe in any given position. Thus, the planar work piece supporting surface of the mitre gauge is movable about both horizontal and vertical axes so as to accommodate any desired angle of contact between the work piece and the cutting tool. The guide fence of the invention employs two mirror image L-shaped brackets each of which has a vertical guide plate that presents a guide surface in perpendicular relationship to the supporting table and means presenting an aligning surface in spaced relationship to the guide surface. In this manner, one half of the fence may be squared followed by movement of the other half of the fence a desired distance and it may then be squared utilizing the two aligning surfaces which can be locked together.

A foldable structure (2) and a method of manufacturing a foldable structure which, when folded produces a curved edge or corner. The structure comprises two panel members (32,34) having a respective edge region (18,20) which are adjacent and are spaced apart. Each edge region has a shoulder (8,10) and a curved portion (12,14). A flexible elongated bridging piece (22) is located between the shoulders (8,10) and defines a foldable region. A flexible lamina (24) covers a respective face of the panel members (32,34) and the flexible bridging piece (22).

Disclosed herein is an automatic apparatus for machining panels or similar articles and, particularly, for drilling and milling them in accordance with the "Folding" system. With this apparatus, the panel to be machined is carried by conveyor means, in a direction parallel to its longitudinal axis, towards drilling and milling devices placed one after the other, the latter being able to mill the panel transversely with respect to the direction in which it moves forward. The operation of the drilling and milling devices takes place contemporaneously in unison, controlled by a feeler device located after the milling devices, which is able to perceive the presence of milling in the panel and to consequently cause the panel to halt and to be in the exact position necessary for the aforementioned drilling and milling devices.
