As shown in fig. 5 and 6, the arrangement density of the air suction holes 34 on the cutter belt 31 and the platen 33 can be the same or different, and when different, the density on the platen 33 is preferably greater than that on the cutter belt 31, so as to provide a uniform air suction position, where the air suction is aimed at making each layer of fabric tightly fit on the surface of the cutter belt 31, thereby avoiding the occurrence of dislocation between layers during cutting and affecting the cutting precision, and the hole diameters of the air suction holes 34 on the cutter belt 31 and the platen 33 can be the same or different, wherein the platen 33 only needs to be arranged at the bottom of the cutting head 32. In the specific implementation process, the flow of the air suction pump of the cutting machine is preferably 4000-8000 cubic feet per minute, and by controlling the numerical values, on one hand, the situation that the fabric cannot move due to overlarge wind power can be avoided, and the situation that the top fabric cannot be adsorbed due to undersize wind power can also be avoided.

In the process of controlling the speed and/or the acceleration, the originally woven spray drawing pattern and the cutting pattern of the cut piece are required to be adjusted as the reference, so that the front and back uniformity is ensured.

As a preference of the above embodiment, the distance from the content of the mark to the edge of the cut piece in the conveying direction is a fixed value, and this setting aims to ensure that the final fabric can visualize the printed fonts after being rolled up, so that the cut pieces can be distinguished without opening the fabric, and are convenient to take and use, wherein the fixed value is convenient to select, and an accurate visible numerical value can be determined according to the size of the rolling paper tube, but the numerical value needs to consider whether the fabric edge positions are flush in the selection process.

As the preferred of above-mentioned embodiment, in the cutting process, set up the hole site of induced drafting on the mesa that supports the cloth, the laminating nature of multilayer fabric is guaranteed in the absorption through wind-force, in the cutting process, the head of cutting is highly different for every layer of fabric, consequently must make the effort to every layer of fabric have the difference, the deviation that cuts that avoids this kind of difference to bring, carry out the adsorbed mode of wind-force to the fabric through cutting the position and fix, because the fabric itself has the hole, consequently the mode of induced drafting from bottom to top can satisfy above-mentioned demand, this kind of mode need not extra fixed knot structure, and can not cause the injury to the fabric surface, can quick open stop, and can avoid and cut the interference problem between the head, high convenience and high speed, and be convenient for control.
