Patent number: 7373707Abstract: The milling apparatus (10) is arranged in such a manner that the deep groove cutter (21) is attached to the milling cutter (20) and the rotational drive shaft (23a) is approximately orthogonal to a spine (16a) of a sheet bundle (16) by the mechanism for tilting the drive apparatus (24) when an EVA-based hot melt adhesive is used. The milling apparatus (10) is arranged in such a manner that the shallow cutter (22) is attached to the milling cutter (20) and the rotational drive shaft (23a) is tilted with respect to a conveying direction of the sheet bundle (16) by the mechanism for tilting the drive apparatus (24) when a PUR-based holt melt adhesive is used.Type: GrantFiled: April 26, 2007Date of Patent: May 20, 2008Assignee: Horizon International Inc.Inventors: Ko Ouchiyama, Hirohito Nakanishi, Shigenobu Fukuda, Kanta Kambara

Patent number: 7353738Abstract: A device for cutting a sub-finished assembly (1) of plastic lens (10) includes a cutting member (2) and a holding member (3). The cutting member has a base (20), an upper plate (21), an upper cutter (23) mounted on the upper plate, a lower plate (22), a lower cutter (24) mounted on the lower plate, guiding posts (25) mounted on the base and guiding the movement of the upper and the lower plates, and a stopper (26). The upper plate moves toward the lens before the lower plate and until the upper cutter contacts the cutting point beside the lens. The stopper stops the upper plate from further moving after the upper cutter contacts the cutting point beside the lens. The lower cutter is moved by the lower plate to cut the lens from the sub-finished assembly of the lens. The holding member holds the lens during cutting.Type: GrantFiled: March 18, 2004Date of Patent: April 8, 2008Assignee: Asia Optical Co., IncInventor: Ying-Chang Chen

Publication number: 20080072730Abstract: A cutting apparatus includes a motor, a gear set, a gliding block, a rotating shaft and a handling element. The gear set includes a first gear part connected to the motor and a second gear part connected to a protrusion member. The center line of the protrusion member is shifted from the center line of the second gear part. The gliding block includes a gliding channel for receiving the protrusion member therein. The protrusion member is linearly moved along the gliding channel back and forth when the protrusion member is rotated in a circular motion. The rotating shaft is connected to an end of the gliding block such that the rotating shaft is rotated with synchronous linear movement of the protrusion member. The handling element has a first end sheathed around the rotating shaft and a second end operated to have the cutting member linearly moved along two guiding tracks.Type: ApplicationFiled: January 22, 2007Publication date: March 27, 2008Applicant: PRIMAX ELECTRONICS LTD.Inventors: Tzu-Feng Tseng, Pei-Yuan Lee

Publication number: 20080041208Abstract: A metal panel shear cutter is designed for metal panels which include support ribs. The metal panel cutter utilizes an anvil type cutting blade positioned at each side of a cutting base. Each cutting blade is pivotally connected to a cutting base in the vertical plane. The cutting base also includes supports for the ribs of the panels to allow for a smooth and clean cut of the panel. The cutting blades and a small portion of the cutting base are pivotally connected to the cutting base in the horizontal plane so they may be pivoted to the desired cutting angle while the metal panel remains fixed with respect to the base. This pivotal portion of the base includes additional supports for the ribs of the panel. These supports are adjustable to accommodate the various angles at which the panels are to be cut.Type: ApplicationFiled: August 18, 2006Publication date: February 21, 2008Inventor: Mark Osgood

Patent number: 7310984Abstract: A forming apparatus (50) includes a roll former (51) operative to roll form a metal strip (100) to form a profiled metal section (10) of generally C section profile including a pan (12) and a pair of upstanding edge margins (14 and 16). The section profile incorporates a longitudinal precamber which is introduced by the forming apparatus by incorporating a prestretching apparatus (52) upstream from the roll former (51), and a bending apparatus (53) located downstream of the roll former (51). The prestretching apparatus differentially stretches the metal strip (100) in its longitudinal direction so as to form portions (101, 102), which are more elongated than a laterally adjacent portion (103) of the strip (100). The differential stretching compensates for longitudinal shortening of the metal strip in forming the profiled section in the roll former (51). The bending apparatus (53) uses a (3) point bending process and includes a reaction stage (60), a fulcrum stage (61), and an action stage (62).Type: GrantFiled: March 25, 2004Date of Patent: December 25, 2007Assignee: Bluescope Steel LimitedInventor: Merrick White

Patent number: RE40605Abstract: An apparatus for cutting a window covering including a head rail, a bottom rail and slats includes a base having a substantially flat cutting surface, and a frame overlying the cutting surface. The base includes a clamping assembly for securing the window covering atop the cutting surface with the bottom rail, slats and top rail in a side-by-side arrangement over the cutting surface. The apparatus includes a cutting assembly having a cutting blade with a cutting edge for sliding along a movement axis having a first component of movement extending in a direction substantially parallel to the cutting surface and a second component of movement extending in a direction substantially perpendicular to the cutting surface. A driver is connected with the cutting assembly for moving the cutting blade toward the cutting surface, wherein the cutting edge simultaneously cuts through the bottom rail, the slats and the head rail.Type: GrantFiled: December 29, 2005Date of Patent: December 16, 2008Assignee: Springs Window Fashions, LLCInventors: Darrell J.
