A dyeing machine with symmetrical double spiral fabric tanks includes a barrel body with a fabric inlet, two spiral fabric tanks arranged side by side with each other in the barrel body and installed on both sides of the fabric inlet respectively, and each spiral fabric tank having a fabric guiding tube, a spiral fabric sliding plate and a receiving tank. The two fabric guiding tubes are disposed proximate to adjacent sides and facing to the front side and arranged symmetrically with respect to the left and right sides. The two spiral fabric sliding plates are coupled to the rear end of the two fabric guiding tubes and configured to be spirally from top to bottom, so that cloths can be dipped and dyed in the two spiral fabric tanks.

Disclosed is a control method for synchronized fabric circulation in a conveyer drive fabric dyeing machine. During a dyeing process of fabric, the fabric is driven by a fabric guide to move in a circulating manner and the time period for a cycle of circulation is set in consistency with the time period that a conveyor moving from a rear end to a front end so as to achieve synchronization that makes the circulation smooth. The control method is performed with a computer or a PLC control unit that is supplied with fabric length data or fabric weight data and fabric unit weight data and, based on such data, performs an automatic operation of computation and supply of a signal to speed controllers of the fabric guide motor and the conveyor motor to set the speeds thereof at a predetermined ratio with respect to each other for synchronized operations.

A system that includes a fabric joining device for manufacturing a fabric item. The fabric joining device includes a first section configured to releasably hold at least a first portion of a fabric item onto a surface of the first section. The fabric joining device also includes a second section configured to releasably hold at least a second portion of the fabric item onto a surface of the second section. One or more first actuators coupled to the second section and configured to rotate the second section toward the first section to fold the second portion of the fabric item onto the first portion of the fabric item and to press the first portion of the fabric item and the second portion of the fabric item together to join the first and second portions of the fabric item.

A circulation protection device is provided for a conveyor-driven fabric dyeing machine that includes a machine body having a front end in which a fabric circulation detection idler and a fabric movement sensor are mounted and a rear end in which a rear fabric guide and a fabric management device are mounted. Control is conducted with a computer program so that when the fabric circulation detection idler detects the fabric is not in movement, the conveyor is shut down; and when the fabric movement sensor detects the fabric is moving excessively fast or slow or gets jamming and stopped, the conveyor is controlled to automatically adjust the speed thereof or stops operation. When the fabric falls from a dyeing tube down to a conveyor, the rear fabric guide adjusts an entry angle of the fabric and the fabric management device allows the fabric to be orderly deposited on the conveyor.
