Abstract
The invention comprises a tearing machine of large width. The feeding station is automatic. A centrifugal separator recycles the scraps recovered by the longitudinal pneumatic transport. It recycles them with the new scraps, in the stack with vibrating walls which extends itself over the entire width of the machine. The compartmentalized suction loading devices assure homogeneity of the fibrous cloth. A fibrous cloth of very high quality is produced on an evacuation conveyor belt. This cloth is homogenous over the entire width of the machine, which may extend to several meters.
