摘要:
A holding member is configured to be inserted into a cutting apparatus including an image scanning device, while holding a sheet-shaped object, so that the object is scanned by the image scanning device and cut by the cutting apparatus. The holding member includes a base having an adhesive part on which the object is removably placed, a transparent sheet holding the object between the base and itself, the transparent sheet having a proximal end fixed to a first side of the base and being movable between a closed position where the transparent sheet is laid over the adhesive part and an open position where the adhesive part is exposed, a first sign located on the base to indicate a type of the holding member, and a second sign located on the transparent sheet to indicate that the transparent sheet is located at the closed position.
摘要:
An apparatus and method for cutting a workpiece or template from wood, plastic, or other media. The apparatus is a flexible cutting rail guide comprising a length of elastomer stock having a cross-section with at least one ninety-degree angle, the elastomer stock being securable to a workpiece or template media. Preferably, the elastomer stock is square in cross-section and has a durometer rating in the range of about 75 to 90. The method teaches the use of a flexible cutting rail guide, workpiece media, and a router to cut a workpiece, comprising the steps of a) defining the desired design shape on the template media; b) removably securing the flexible cutting rail guide to the template media; and, c) cutting the template media by guiding the router along the flexible cutting rail guide. The invention further provides a method for cutting two or more identically shaped workpieces using the pattern or template.

Pilot device for a suspended cutting knife of a cutting head of an automatically controlled cutting machine for cutting fabric sheet material spread out on a cutting table in multiple layers. The cutting head is controlled by moving the cutting head along the X- and Y-axes and pivoting about a Z-axis for moving the knife tangently along a predetermined cutting path. The cutting knife is reciprocally movable along the Z-axis. The cutting head includes a device for guiding the unsuspended part of the cutting knife and a pressure foot rigidly connected to the pivotal cutting head. The suspended end of the knife is mounted in the cutting head so as to be freely rotatable around the Z-axis. The guiding device is adjacent to the free end of the knife and comprises a socket rigidly connected to the cutting head having a support which is freely rotatably mounted in the socket around a vertical axis located in front and adjacent to the cutting edge of the cutting knife and parallel, at a predetermined distance, to the Z-axis. The support has a slot surrounding the flanks of the knife and a sensor for detecting the instantaneous rotation angle and/or its direction of the support relative to the socket and providing correcting signals.

An automatically controlled cutting machine for cutting multiple layers of fabric sheet material spread out on a cutting table, the cutting machine including a cutting tool which is rotatable about a Z-axis and which includes a cutting knife mounted on a cutting head and a guiding device for guiding the the cutting knife. One end of the knife is mounted in the cutting head so as to be freely rotatable around the Z-axis, and the guiding device is arranged adjacent to the remaining free end of the knife and comprises a socket rigidly connected to the cutting head, and a support which is freely and rotatably mounted in the socket around a vertical axis located in front and adjacent to the cutting edge of the knife, and parallel and spaced a predetermined distance from the Z-axis. The support has a slot surrounding the flanks of the knife. The slot is eccentrically positioned relative to the vertical axis and extends to the trailing edge of the knife such that the knife can twist about the vertical axis under the influence of lateral loads occurring during cutting to bring the force between the sheet material and the flanks of the knife and the bending force of the knife into a balanced equilibrium state.

An apparatus for cutting sheet material spread in one or more layers over a supporting surface uses a reciprocating cutting blade cutter movable in two coordinate directions in the plane of the supporting surface to enable the cutting blade to follow a desired line of cut relative to the sheet material. The cutting blade has a leading cutting edge that performs the actual cutting operation with a slicing action. During the cutting operation, mechanical means within the apparatus produces blade dither about the axis of reciprocation in synchronism with the reciprocation strokes of the blade.

A sheet processing apparatus (1) includes a first processing section (1000), a second processing section (2000), and a third processing section (3000) arranged on a straight line, and conveys a sheet (4200) therebetween. The first processing section (1000) forms a plurality of first processing lines extending in a first direction (an X axial direction) on the sheet (4200), by moving a plurality of tools (1110-1260) to the first direction in relation to the sheet (4200). The second processing section (2000) forms a plurality of second processing lines to a second direction (a Y axial direction) orthogonal to the first direction on the sheet (4200), by moving a plurality of tools to the second direction in relation to the sheet (4200). The third processing section (3000) forms a third processing line (aslant line, curve line) on the sheet, by relatively moving the sheet (4200) and the tool (3110, 3120).
摘要:
A holding member includes a base, a transparent sheet, first, second and third signs. The base has an adhesive part on which a sheet-shaped object is removably placed. The sheet holds the object between the base and itself. The first sign indicates a type of the holding member. The second sign indicates that the sheet is located at a closed position. The second sign on the sheet and the first and third signs on the base are located at a front part of the base with respect to an insertion direction of the holding member when the sheet is located at a closed position. The first to third signs are located between a front end of the adhesive part and a front end of the base with respect to the insertion direction when the sheet is located at the closed position.
摘要:
A method and apparatus for cutting sheet material utilizes a closed loop automatically controlled cutting machine having a reciprocating cutting blade as the cutting tool. Sheet material to be cut is spread in multiple plies to form a layup, and the cutting blade and the material are then moved relative to one another in cutting engagement along predefined lines of cut. During cutting, a sensor detects a cutting parameter that is affected by the interaction of the cutting blade and sheet material, and signals provided by the sensor are fed back in the closed loop automatic control mechanism to adjust or initiate further steps in the cutting operation. Such adjustment or initiation alters the cutting machine operation for cutting conditions in real time in order to improve the overall performance of the machine.
摘要:
A system and method for cutting multiple pattern pieces from a layup of sheet material employing two-stage digitizing to produce a cutting program in which contour segments of individual pieces are cut by a cutting blade in different directions about the pattern pieces. The direction in which a particular segment of a pattern piece contour is cut and the order in which the segments are cut are selected to most easily facilitate the cutting operation. The point on any given pattern piece toward which a cutting blade is advanced from different directions is generally the point of closest approach to an adjacent or contiguous pattern piece in the marker cut in the sheet material. The feed rate and tangency of the cutting blade are also regulated at sensitive cutting points such as the points of closest approach to an adjacent pattern piece.
摘要:
Method and apparatus for controlling a cutting blade which cuts pattern pieces from layups of sheet material held in a compressed condition by vacuum employs a pressure sensor to detect previous cuts near the blade as the blade advances along a cutting path through the layup. The sensor has a pickup which translates with the blade along the cutting path and the reduced pressure produced by the vacuum in the previous cuts is sensed as the blade comes into close proximity to the cuts. When a cut is detected, control mechanism regulating the motions of the blade through the layup respond to the detected cut and vary the cutting parameters of the blade to permit more accurate cutting in regions adjacent the cut.
