Description

Technical Field

[0001] The utility model relates to the field of non-woven preform production, and particularly relates to an automated production line for flat preforms. Background Art

[0002] The processes of the needled non-woven fabric (100) preform mainly include material cutting, material laying, flat preform needling, and flat preform cutting. At the present stage, in the production process of the needled flat preform, except for the flat preform needling process which is automatically operated by a machine, all other processes are manually operated. In the above-mentioned production process, there are the following deficiencies:
