| 摘要 | A meshes cutting machine for permitting the continuous cutting of a length of meshes which are being moved or advanced continuously rather than intermittently. The meshes cutting machine includes a pair of cooperating cutting edges placed in a vertical direction, with the upper cutting edge being stationary and the lower cutting edge being adapted to move vertically to cut the widthwise members of the meshes; a guide groove adapted to guide the meshes which are cut continuously; and a drive pawl mechanism adapted to drive the meshes forward and, at the same time, to position the lengthwise member composed along the advancing direction of the meshes at a desired spacing from the cutting line of the meshes maintaining parallelism with the aforesaid cutting line and with the advancing direction. This drive pawl mechanism may shift in a direction perpendicular to the cutting line by means of a screw mechanism to change the aforesaid spacing of the lengthwise members of the meshes from the cutting edges. | ||||||
| 权利要求 | 1. A meshes cutting machine provided with a pair of cooperating cutting edges for cutting meshes consisting of wire members, and with a mechanism for moving said meshes, comprising: a guide groove extending along the extension line of the cutting line of said meshes in the advancing direction of said meshes; and a drive pawl mechanism located on the open side of said guide groove and adapted to shift the lengthwise members of said meshes in parallel with said guide groove. 2. A meshes cutting machine as set forth in claim 1, wherein one of said pair of cooperating cutting edges moves in the advancing direction of said meshes in addition to the vertical movement thereof. 3. A meshes cutting machine as set forth in claim 1, wherein the distance of said drive pawl mechanism from said guide groove may be varied. 4. A meshes cutting machine as set forth in claim 1, wherein said drive pawl mechanism is provided with pawls having slits in the center portions thereof. 5. A meshes cutting machine as set forth in claim 4, wherein a meshes holding cover is provided above said slits. 6. A meshes cutting machine as set forth in claim 1, wherein said drive pawl mechanism is provided with pawls which effect a rocking motion relative to an endless chain. 7. A meshes cutting machine as set forth in claim 6, wherein the inclined angles of said pawls which effect a rocking motion, may be varied by means of a cam. 8. A meshes cutting machine as set forth in claim 1, wherein the pair of cooperating cutting edges for cutting said meshes consists of a pair of shearing edges. |
