Abstract: A saw guide to enable a user to cut a straight line using a hand saw consists of a base having a slot formed therein which divides the base into first and second side-by-side sections. A fixed guide is mounted above the first section, with the central portion thereof being spaced apart from the base to form a cavity into which the board or other work to be cut is inserted. An adjustable guide is mounted above the second section, with the central portion thereof forming an adjustable cavity through which the board cut project. The adjustable guide includes manually operable adjustment knobs at the upper end of threaded bolts which extend through the ends of the adjustable guide and, at their lower ends, screw into threaded collars in bores within the base. As the knobs are turned, the adjustable guide descends, thereby decreasing the height of the adjustable cavity until the adjustable guide clamps against the board and holds it tightly against the base.

Abstract: A carpenter's saw designed for use in beveling the ends or edges to form a miter joint is disclosed. The saw comprises mainly a saw base and a saw support. The saw base includes a horizontal base face having a fan-shaped portion disposed at the center thereof. The saw support is fastened to the fan-shaped portion. A hacksaw is mounted on the saw support. The saw support comprises a suspension arm which is pivoted horizontally to the bottom of the fan-shaped portion. Two seats are separately arranged at both ends of the long axis of the suspension arm. Located on each of the two seats are arc-shaped recesses which have the same curvature radii. Two rotating members are lodged separately in the two arc-shaped recesses in order to rotate along the arc-shaped rails provided. Two support rods are vertically mounted on the rotating members for the hacksaw to be fastened thereon.

Abstract: During, for example, package production, printed sheets are carried by gripper bars through a cutting station of a machine. Front waste strips are removed from the printed sheets and are carried to an ejection device, but before reaching the ejection device, a camera and flash scanning unit scans the area of the front waste strip which has been marked with color registration marks and also includes at least a portion of a cut edge. An image processing unit compares this sample image to a reference image to conduct a quality check on the precision of the printing and cutting registration.

Abstract: A distinctive apparatus and method for selectively providing predetermined segments of web material comprises a supplying mechanism for providing the web material. A first sensing mechanism detects a reference marker on the web material to generate at least one reference marker datum which is associated with a selected web segment. A separating mechanism includes a sensor mechanism for providing at least one separation datum, and divides the web material along a separation region during a production of the web segment. A phase regulating mechanism controls a relative phasing between the reference marker detected by the first sensing mechanism and the dividing by the separating mechanism. The phasing is conducted with respect to a set reference value.

Abstract: A cutter box for receiving a loaf of bread or the like and guiding slicing of the loaf, including a base having a bottom, a grill with the base having a rim or edge for positioning the grill in the base above the bottom, and a pair of guide plates, with the grill having a plurality of parallel spaced slots for receiving the guide plates, each of the guide plates having a vertical member with a slot for guiding a knife and positionable in the slots of the grill, and a horizontal member positionable in the guide space for holding guide plates in place with the grill is placed in the base, with guide plates being removable from the grill and insertable in different slots.

Abstract: A bread cutting device including an open top container or box and a tray is removably mounted on the box and includes a plurality of parallel spaced rails which supports a loaf of bread to be cut. A lateral back stop is mounted at one end of the box and extends upwardly from the tray in position to be engaged by the end of the loaf. A pair of slicing guides are received within spaces between adjacent rails and each guide includes a series of parallel slits which extend from the upper end of the guide to a location spaced from the lower end. A knife inserted in aligned slits in the guides will cut a slice from the loaf and the crumbs fall through the spaces between the rails for collection in the box.

Abstract: The present invention relates to a method and apparatus for marking and cutting a flexible web that can be supplied from a supply roll of material onto a generally flat working surface or bed to a take-up roll. While the present invention is particularly adapted for marking and cutting fabric, such as may be used to manufacture upholstered furniture, such as couches, love seats, chairs and the like, the invention may also be used to mark and cut almost any flexible web, and particularly any web that is susceptible of experiencing dimensional distortion, such as bowing, skewing or stretching in unusual directions. The apparatus utilizes computer control and video imaging to identify design features and to locate them relative to pieces so that the item of furniture has design features at the desired locations.

Slides are slidably seated on the saw guides and have bearing pads extending towards each other and guide means cooperating with those of the saw guide elements. Biasing means bias the slides upwardly but pressure exerted on the pads by the saw can move the slides downwardly to increase the depth of cut permitted. The cooperating guide means desirably comprise slots in the saw guide elements and web portions in the slides which are seated in the slots.
