Abstract: The invention relates to the fixing of staves (10) provided with points (12) to the cylinder (1) of a textile machine drum. Inside the cylinder (1) bars (6) provided with threaded holes (8) are slid. The half-openings (14) of the bases (11) of the staves (10) are facing each other by pairs. The pieces (18) provide for the blocking. Application: time reduction of labor for the mounting and replacement of the staves, possibility of fitting long cylinders with small diameters without the need for the operator to pass his hand inside the cylinder.

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.
