cycle of operation is completed successive sequence of the above mentioned cycles will cause cycle shiftings of the convolutions of fabric in the right direction it should be recognized that the longitudinal movement may be imparted to the rear guide member 3 39 instead of the front guide member 3 a driving system for the timed movements of the guide assembly and the front guide member will be described later a wince machine incorporating the guide assembly constructed in accordance with the present invention in place of a helical guide member is shown in fig1 and 2 wherein the reference numeral 10 denotes a liquid bath 11 11 39 side walls of the tank 15 a wince roll 1 a guide roll 2 a guide assembly in accordance with the present invention and 18 is a driving chain the wince roll is driven for rotation by means of an electric motor 23 the guide roll 1 is suitably supported for free rotation below the roll 15 and above the liquid surface in parallel to said roll 15 the guide assembly 2 is disposed forwardly below said guide roll the chain 18 driven from another electric motor 24 along a predetermined vertical path 20 around sprockets 19 shown in fig2 has a hook 27 to which a leading end of the fabric is connected with a length of a connection cloth this path determines the length of convolution of fabric which forms a plurality of pleats 51 in the bottom of the bath the treating liquid is circulated by a pump means 26 through a deflector means 27 in operation with actuation of motors 23 and 24 the roll 15 is rotated in the direction of an arrow and the chain is driven in the same direction along the.
