In the present embodiment, a plurality of grippers 10 and saw cutters 30 are distributed on the periphery of the material 20, and during the reciprocating movement along the illustrated X direction, as illustrated by an example that the gripper assembly of fig. 6 and 7 includes two grippers 10, two grippers 10 are oppositely arranged on the periphery of the material 20, when the material 20 is fed for a set length, one set of the associated grippers 10 (first set of grippers 10) and saw cutters 30 starts to accelerate from the origin, when the first set of the associated grippers 10 and saw cutters 30 is at the same feeding speed as the material 20, the set of grippers 10 grip the material 20, the set of saw cutters 30 cut the material 20 along the direction perpendicular to the feeding direction, i.e., the illustrated Y direction, after cutting the material 20, the set of grippers 10 release the material 20, decelerate to stop at the end position, and then return toward the origin, during which the second set of the associated grippers 10 and saw cutters 30 starts to accelerate from the origin, the above process is repeated, and when the two groups of clamps 10 are in the staggered position, the second group of clamps 10 are in the clamping state, the first group of clamps 10 are in the open state, and the opening of the first group of clamps 10 in the open state can allow the second group of clamps 10 to pass through, so as to achieve the avoidance, and particularly the avoidance process in the staggered position is shown in fig. 7. When the jaw assembly includes more than three jaws 10, similar to the process described above, the first set of jaws 10 and the second set of jaws 10 are performing the process described above, and the remaining sets of associated jaws 10 and saw cutters 30 are performing the process described above, with one jaw 10 in the clamped position and the other in the open position, to effect avoidance. It will be appreciated that the above process is controlled by a control system which controls the opening and closing and movement of the jaws 10 and the cutting and movement of the saw 30 to ensure that the length of material 20 cut at a time is consistent. Through above-mentioned structure and working process, it is fixed to carry out the centre gripping through clamp 10 when saw cutting, has improved the stability of saw cutting to can realize dodging of clamp 10, realize many saw cutting machine 30 continuous operation, improve production efficiency.
