A punching device includes a base, a linkage assembly, a carrying assembly, a punch and a pressure arm. The linkage assembly includes a pair of linkage members, a rotating member, a first connecting rod, a second connecting rod and a third connecting rod. The rotating member is rotatably mounted on the supporting member, the pair of linkage members is movably mounted on the rotating member, the first, the second and the third connecting rods connects in turn. The carrying assembly is rotatably connected to the third connecting rod and movably supported by the loading member. The punch is mounted on an end of the rotating member. The pressure arm is rotatably connected to the supporting member and the pair of linkage members to drives the carrying assembly to position a workpiece and the punch to punch the workpiece.

The dispenser assembly is for opening a pouch or packet structure. The dispenser assembly includes a container structure having an interior cavity. The cavity has a sufficient dimension such that the packet structure may be stored therein. The dispenser assembly includes a cutter for severing the pouch or packet structure. The cutter is secured to or removably stored in the container. The cutter may be constituted by a slider structure, guillotine cutter, or U-shaped member.

A miter saw which prevents deterioration in perpendicularity of a cutting blade to the upper surface of a base part when slide of a pipe is regulated by pressing a pipe. In a miter saw, a pair of pipes support a cutting part, on one end side. On the other end side, the pipes are surrounded and supported slidably by a first slide support part of a support member of a turntable. A virtual plane including the axes of the pair of pipes is substantially parallel to the pivotal direction of a disc saw blade. A first screw is screwed in the first slide support part. An end part of the first screw contacts and presses a pipe. This end part is engaged with the pipe so as to restrict slide of the pipe relative to the first slide support part.

A paper cutting device, for cutting multiple sheets of paper stacked in layers on a table, comprises a paper retainer (2) descending from an upper side along a guide and a cutter (3) diagonally ascending from the lower side. A receiving part (18) is mounted on the lower surface of a paper retaining frame (20). The receiving part (18) is formed by joining a base plate (36) with a large elastic modulus such as a metal to a resin receiving plate (37). A slip prevention structure is installed on the junction surfaces of the base plate (36) and the receiving plate (37) to suppress the extension/retraction of the receiving part of the paper retainer so as to prevent wrinkles from occurring in the paper near a blade receiving surface when the paper is cut off.

A control device for a cutting blade, particularly for cutting-off machines for logs of web material, interrupts operation of the cutting blade when deformation of the blade reaches a preset deformation value and resumes operation of the cutting blade when the deformation of the blade is less than another preset deformation value. The control device includes a measuring device for measuring deformation values of at least a portion of the cutting blade, at least one comparator for comparing the measured deformation values with at least one preset deformation value set by an operator, and an actuator which sends, according to signals coming from the comparator, control signals to a motor of the machine to control the start up and/or the stop of the motor.

A paper cutter includes a base having a stationary blade; a fixing seat fixed to the base adjacent to one end of the stationary blade and having a connecting portion extending upward from the base, wherein the connecting portion is atop, peripherally formed with a plurality of teeth, and is formed centrally with a through hole for allowing a shaft to pass therethrough; a connecting element having a rotatory portion that is formed with a slot for allowing the shaft to pass therethrough and being atop provided with recesses for receiving the teeth; and a movable blade having a lower edge formed as a curved edge and having a front end fixed to the rotatory portion. Thereby, when the movable blade is pushed downward, the connecting element is driven to rotate and move along the teeth while approaching and sliding with respect to the stationary blade.

The design and method for no sew fabric quilting is described that produces quilt like pictures for home decor or other uses. A pliable or foam like material serves as the quilting medium to which fabric is attached by tucking the fabric into cut pattern grooves. A thin rigid base provides support to the quilt picture. An adhesive coating with a paper carrier is part of the cut pattern medium and provides added support to the cut grooves in holding fabric in place. The paper carrier, when peeled off the adhesive also serves as a pattern piece to cut the fabric. Fabric is placed on the adhesive and edges tucked into pattern grooves using a narrow scalpel like tool. A thin foam sheet attached to the base backside finishes the item and is then ready to be hung after adding a wall hanger.

A knife assembly (10) particularly adapted for coupling with an extruder barrel (26) is provided having a knife shaft (16) supporting a knife unit (14), with the knife shaft (16) axially rotatable and axially shiftable through fore and aft limits. The assembly (10) may be adjusted during operation without interrupting the axially rotation of shaft (16), using adjustment mechanism (24) located in a safely remote position from knife unit (14). The preferred assembly (10) includes axial shift limiting structure (114, 116, 124) serving to limit the extent of fore and aft axial movement of shaft (16). The mechanism (24) allows fine adjustment of the position of knife unit (14) relative to the extruder barrel (26), and also permits monitoring of the wear of knife unit (14).

A drive mechanism for a hole punch includes a frame and a lever having a first end and a second end. The lever is pivotally coupled to the frame at a pivot point disposed intermediate the first and second end thereof. The frame includes a lever engaging portion for engaging with a frame engaging portion disposed at the second end of the lever, such that as the first end of lever is pivoted about the pivot point, the frame engaging portion is arranged to move along the lever engaging portion to cause the pivot point to move with respect to the frame.
