Description

Technical Field

[0002] For example, patent announcement No. CN211112464U discloses a flattening mechanism for a jet loom. The utility model includes a jet loom body and a discharge platform arranged at the discharge port of the jet loom body. The discharge platform is symmetrically provided with flattening components on both sides along the width direction of the cloth. The flattening component includes a mounting plate fixedly connected to the edge of the discharge platform, a rotating shaft arranged on the mounting plate and arranged in a horizontal direction, a flattening roller fixedly connected to the rotating shaft, and a driving motor arranged on the mounting plate and connected to the rotating shaft. One end of the flattening roller close to the other side of the flattening component is inclined toward the movement direction of the cloth. Through the above arrangement, the flatness of the cloth when winding is increased.
