Abstract
Apparatus for the wet treatment of lengths of textile material in hank form has a plurality of chambers through which the lengths of material pass in succession and transport means which convey the length of material. To enable more or less elastic types of material to be subjected to wet treatment under desired uniform treatment conditions, the quantities of material contained in the individual chambers are monitored by sensing devices which control the rate at which the material is conveyed by the transport means.

Apparatus for controlling the rate of movement of a length of textile material through a series of treatment chambers in each of which is monitoring means for monitoring a predetermined change in the quantity of material therein, said apparatus comprising, for each chamber, rotary guide means for introducing said material into such chamber;
- a pair of rotary squeeze rolls between which said material may be gripped in being withdrawn from such chamber, one of said squeeze rolls being driven;
- shift means connected to one of said squeeze rolls and responsive to operation of the monitoring means in such chamber to move such squeeze roll toward and away from the other whereby said squeeze rolls are enabled and disabled to grip said material and withdraw it from such chamber;
- first material support means adjacent said rotary guide means;
- second material support means adjacent said squeeze rolls, said first and second support means being operable to support said material when said squeeze rolls are so disabled;
- and means coupling said first and second material support means to one another and to said shift means for moving said support means into and out of material supporting positions in response to movements of said shift means.
In apparatus for controlling the rate of movement of a length of textile material in hank form successively through a series of wet treatment chambers in each of which is monitoring means operable to sense a predetermined change in the quantity of material therein, said apparatus including transport means normally operable to withdraw material in succession from each of said chambers and feed such material to the next adjacent chamber at a selected rate of speed, said apparatus also including means responsive to the sensing by said monitoring means of a predetermined decrease in the quantity of material in any one of said chambers to reduce the rate of speed at which material is withdrawn from said one of said chambers, the improvement wherein the monitoring means for each of said chambers comprises a grate on which material is supported;
- means mounting said grate within said chamber to rise and fall in response to a decrease or an increase, respectively, in the quantity of material supported thereby;
- actuating means coupled to said grate for movements in response to the rise and fall of said grate;
- and means responsive to movement of said actuating means a predetermined distance as a result of the fall of said grate to reduce the rate of withdrawal of material by said transport means from the associated chamber.
