Fastening system for a compaction module on a spinning machine

A fastening mechanism that detachably fastens and positions a compaction module on a drafting unit of a spinning machine, wherein the compaction module has a carrier with at least one suction channel that is connected to suction inserts of compaction elements movably mounted on the carrier, the fastening mechanism comprising:

• two clamping elements that are fastened spaced apart from one another on the spinning machine by retaining members;
• each clamping element comprising a first receiving slot that is open on one side and has a retaining section by means of which a retaining element that is fastened on the carrier engages and forms a positive-fitting clamped connection with the clamping element;
• and
• wherein the positive-fitting connection allows a pivot movement of the carrier in a pivot plane that extends parallel to opposing planes in which the receiving slots of the clamping elements lie, wherein each respective clamping element comprises a stop that limits the pivot movement.

A fastening mechanism that detachably fastens and positions a compaction module on a drafting unit of a spinning machine, wherein the compaction module has a carrier with at least one suction channel that is connected to suction inserts of compaction elements movably mounted on the carrier, the fastening mechanism comprising:

• two clamping elements that are fastened spaced apart from one another on the spinning machine by retaining members;
• each clamping element comprising a first receiving slot that is open on one side and has a retaining section by means of which a retaining element that is fastened on the carrier engages and forms a positive-fitting clamped connection with the clamping element;
• wherein each clamping element further comprises a second receiving slot that is pen on one side and has a retaining section that forms a positive-fitting connection to a retaining element of a tube element;
• and
• wherein a longitudinal axis of the first receiving slot intersects a longitudinal axis of the second receiving slot at an angle (c) on each clamping element.

• and
• wherein the retaining member of the respective clamping elements are formed by a U-shaped base section attached below the first receiving slot.

A coupling device for connecting a suction channel integrated in a carrier of a compaction module on a drafting unit of a spinning machine to a suction tube that is connected to a central suction channel, comprising:

• a fastening mechanism, the fastening mechanism further comprising
• two clamping elements that are fastened spaced apart from one another on the spinning machine by retaining members;
• and
• each clamping element comprising a first receiving slot that is open on one side and has a retaining section by means of which a retaining element that is fastened on the carrier engages and forms a positive-fitting clamped connection with the clamping element;
• and
• a second receiving slot that is open on one side and has a retaining section that forms a positive-fitting connection to a retaining element of a tubular element;
• an end ring attached on an end of the suction channel and located in a region of the fastening mechanism, the end ring projecting over the suction channel in a longitudinal direction and having an annular outer surface that extends conically inward and is directed away from the suction channel;
• wherein a conically outwardly extending annular inner surface of the tubular element rests on the conically inward annular outer surface of the end ring;
• and
• wherein the suction tube sealingly rests with an inner surface thereof on an outer circumference of a free end of the tubular element.
