Problems solved by technology

In addition to the complexity of the mechanism, the high reciprocating rate results in considerable noise when the tool is driven
Also, when operating at such speeds, it is difficult to precisely control the blade
[0003] Another problem that arises with cutting machines constructed in the manner described above is that the blades tend to wear quickly and need to be replaced frequently

Embodiment Construction

[0016] Such as figure 1 As shown, the cutting table, generally indicated by reference numeral 10, includes a frame 12 and a sheet-like process material support surface 14 adapted to carry at least one layer of process material 16, such as but not limited to Leather or vinyl film. A bracket 18 is attached to the frame for reciprocating movement in a first direction indicated by an arrow marked "X". The cutting head 20 is mounted to the carriage 18 and is movable back and forth along the carriage 18 in a second direction indicated by an arrow labeled "Y". Both carriage 18 and cutting head 20 move in response to commands from controller 21 . As will be described in more detail below, a reciprocating assembly, generally designated 30, is mounted to cutting head 20 and is movable between an operative position in which they engage the material 16 to be processed, and an inoperative position, In said non-working position they are lifted away from the processing material. During o...

Abstract

In a resonating assembly, a beam having a pickup thereon is positioned proximate to a magnet which passes across the pick up at a predetermined frequency. The passage of the magnet across the pick up establishes an alternating magnetic field that in turn causes the beam and pick up to vibrate. A blade is mounted on the beam and vibrates therewith so that when the blade is brought into engagement with a layer of sheet type work material the vibratory amplitude of the blade causes the blade to cut through the material as it is moved in engagement therewith.

Description

technical field [0001] The present invention relates generally to cutting sheet-form work material, and more particularly, the present invention relates to cutting said material by a vibrating blade. Background technique [0002] Sheet-like process materials, such as those used in the manufacture of clothing, as well as upholstery leather and polyethylene in furniture and automobiles, are often cut by laying the process material on a flat support surface and reciprocating over the process material carried by the cutting head blade, while the blade engages and cuts the material to be processed. Generally, the cutting head is attached to a beam that is movable along the cutting table while the cutting head moves along the beam in response to commands from the controller. These blades are capable of reciprocating at speeds of 20,000 cycles per minute and above. Thus, a complicated mechanism must be used to drive the blade. In addition, these mechanisms must be able to move b...
