  • Publication number: 20090293992
    Abstract: A system and method for cutting a profile along a linear edge of a wooden workpiece utilizes two spaced-apart rotatable cutting tools whose cutting edges mirror one another and which are mounted for rotation about parallel axes. The cutting tools are rotated in opposite rotational directions, and a support surface supports the workpiece for movement along each of the two cutting tools. By positioning the workpiece upon the support surface so that the linear edge thereof extends between the two cutting tools, the workpiece can be moved in one direction into cutting engagement with a first of the rotating cutting tools and subsequently in the opposite direction into cutting engagement with the second of the rotating cutting tools. By halting and subsequently reversing the movement of the workpiece along the first cutting tool before the cutting edges thereof exit a trailing (side) edge of the workpiece, the likelihood that the workpiece will be damaged from the profile-forming process is reduced.

    Abstract: A method of fabricating a polishing pad in which a pad material includes a polishing layer overlying a substantially optically transparent backing layer is subjected to a process in which an optical window is formed in the pad material by removing a portion of the polishing layer and exposing an underlying portion of the substantially optically transparent backing layer. Prior to forming the optical window, the polishing layer is bonded to the backing layer to form a sealed interface, then a portion of the polishing layer is mechanically cut away from the backing layers. Since the backing layer is not pierced during the removal process, a liquid, such as an aqueous polishing slurry, cannot leak through the optical window and on to underlying portions of a polishing apparatus to which the pad material is mounted.

  • Patent number: 5975180
    Abstract: In a process and apparatus for the production of panels, plates or sheets are cemented on opposite sides of an intermediate layer of honeycomb with transverse openings constituted by a network of strips of constant width defining the openings. The edges of the strips defining the network are cemented on opposite sides of the layer and the plates or sheets are applied on the cemented edges. Two lateral parallel grooves are formed intermediate the thickness of the longitudinal edges of the intermediate layer with the layer contracted, such that the strips are flat against each other. Then these grooves are used to guide the layer when the layer is pulled out to form the openings. The necessary reduction of the width of the layer is effected by inserting two lateral convergent guides in the grooves on opposite edges of the layer, and forcing the layer to move in the direction of convergence of these guides.

    Abstract: A device and method for superficially incising a sausage-like meat product includes a plurality of rotatable cutting elements which are arranged to define a chute therebetween. Each cutting element includes a cylinder and has a circular blade which projects radially from the cylinder. The centers of the respective blades, also located in the cylinder, define a base plane and the blades are all similarly tilted to rotate in tilt planes which are angled from the base plane. In the operation of the device, all cutting elements are simultaneously rotated and a meat product is inserted into the chute. Rotation of the cutting elements simultaneously causes the cylinder to draw the meat product through the chute and causes the blades on the cylinder to superficially cut a helical shaped incision into the meat product. The depth of the cuts are established by the projection of the blades, and the pitch of the helical incisions, can be controlled by the tilting of the cutting elements.

Each groove group has at least two grooves which are formed parallel to one another. If the vibratory body has an annular shape, a groove forming member having as many cutting members as grooves in each groove group moves in a radial direction of the vibratory body while the cutting members rotate, simultaneously cutting each groove of a groove group in the surface of the vibratory body. When advancing vibratory waves are generated in a circumferential direction of the vibratory body, the state of vibration of the grooves in a groove group differs, and the resonance of the grooves is suppressed. If the vibratory body has a linear shape, the cutting members rotate as the groove forming member moves perpendicular to the vibratory body, simultaneously cutting each groove of a particular groove group.
