Pneumatic suction apparatus for tensioning, reversing and conveying away a tubular knitted article

The apparatus comprises a duct (12) movable axially within a tubular wall (1) so as to form with the latter a cavity (I) with grill (14) and an expansion piece (7) shaped so as to cooperate with the upper edge of the duct (12) when the latter is raised so as to close it off and when the latter is lo...

Beschreibung
Zusammenfassung:	The apparatus comprises a duct (12) movable axially within a tubular wall (1) so as to form with the latter a cavity (I) with grill (14) and an expansion piece (7) shaped so as to cooperate with the upper edge of the duct (12) when the latter is raised so as to close it off and when the latter is lowered so as to form an annular space; a body (18) with holes (20) for entry of the air into the cavity (I) is provided at the end of the tubular wall (1); the duct (12) is movable through a central hole (18A) of the body (18) and has a collar (24) which closes off said holes (20) when the duct (12) is raised, and has holes (26) which, when the duct (12) is raised, are located above said body (18) and, when the duct (12) is lowered, are closed off by the wall of the hole (18A); the suction current is created in said duct (12) during the two phases of tensioning and reversing.
