Abstract
ABSTRACT OF THE DISCLOSURE
In a rotary dyeing system for dyeing hosiery articles, a rotary cylinder is divided into a plurality of compartments for receiving bundles of dry articles therein. Each compartment is provided with a pivotable plate means which, upon wetting of the articles and shrinkage thereof, is forced during the dyeing cycle against the articles to maintain them compact and stationary to prevent tangling thereof.

Claims (18)
1. A machine for dyeing flexible hosiery articles including a vat for containing a dye bath, a cylinder mounted for rotation within said vat, said cylinder defining a chamber for receiving articles to be dyed, means dividing said chamber into a plurality of compartments, and means within each compartment for effectively reducing the size of each compartment to eliminate excessive movement of articles within the compartment upon wetting of the articles in the dye bath.
2. A machine as recited in claim 1, wherein said means within each compartment comprises a displaceable, open-work plate member coupled to said means for dividing said chamber into a plurality of compartments.
3. A machine as recited in claim 2, and further including means within each compartment for biasing said plate member into engagement with said hosiery articles.
4. A machine as recited in claim 2, and further including means to limit the extend of displacement of each plate member.
5. A machine as recited in claim 4, and further including releasable latch means to prevent said plate member from pivoting to increase the effective size of the compartment housing wet hosiery articles.
6. A machine as recited in claim 2 wherein said means within each compartment for effectively reducing the size of the compartment includes biasing means for positively urging said plate member in a direction to reduce the compartment space occupied by wetted hosiery articles.
7. A machine as recited in claim 6, wherein said biasing means comprises fluid means.
8. A rotary dyeing machine for fabric articles including a casing, a cylindrical tank defining a chamber for receiving a dye bath therein, means for mounting said cylindrical tank for rotation, means for rotating said tank at a selected speed, said tank further including door means for providing access to said tank chamber, partition means for separating said chamber into a plurality of compartments, said door means permitting the loading of fabric articles to be dyed within said compartments, and means for reducing the size of the compartments upon shrinkage of the fabric articles upon wetting of the article by a dye bath.
9. A rotary dyeing machine as recited in claim 8, wherein said means for reducing the size of the compartments including an open-work plate, means hingedly mounting said plate to said partition means adjacent the axis of rotation of said cylindrical tank, said plate being displaced by centrifugal force upon rotation of said cylindrical tank to engage and compact fabric articles within the chamber, and latch means to prevent displacement of said plate in a direction away from said fabric articles.
10. a rotary dyeing machine as recited in claim 9, and further including means applying a positive biasing force to said plate.
11. A rotary dyeing machine as recited in claim 10, wherein said means applying a positive biasing force to said plate comprising fluid means positioned intermediate said plate and said partition means.
12. In the dyeing of textile goods wherein bundles of dry articles are subjected to a dye bath during a dyeing cycle and maintained in a controlled, compact position to prevent tangling of the articles comprising, a rotary dyeing machine including a casing, a cylinder rotatably mounted within said casing and defining a chamber for receiving articles and a dye bath. means for selectively rotating said cylinder and articles placed therein, said casing having means for directing fluids thereto and for permitting discharge therefrom, said cylinder further including a plurality of door means for providing access to said cylinder chamber for facilitating loading of articles therein, partition means within said cylinder for separating said chamber into a plurality of compartments, each of said compartments being of a size to receive therein bundles of dry textile articles to be dyed, plate means within each of said compartments, each said plate means including a generally rectangular plate of open-work construction extending from adjacent the axis of rotation of said cylinder radially outwardly to a position in close proximity to cylinder outer peripheral wall, means pivotably mounting said plate to said partition means along a first edge portion, said plate having an opposed second edge portion adapted to be displaced by centrifugal force relative to said cylinder peripheral wall upon rotation of said cylinder, latch means for retaining said second edge portion of said plate in various positions relative to said partition means, said bundles of articles upon being wetted by the dye bath shrinking in size and centrifugal force upon rotation of said cylinder.
13. In the dyeing apparatus of claim 12, means applying a biasing force to said plate to effectively reduce the size of the compartment housing the wetted articles.
14. In the dyeing apparatus of claim 12, latch means for retaining said plate second edge portion in various positions relative to said partition means.
15. In the dyeing apparatus of claim 14, said latch means including a spring biased plunger secured to said plate means and a series of ratchet teeth secured to the inner surfaces of said cylinder peripheral wall.
16. In the dyeing of textile articles wherein a series of bags of articles are placed within as prescribed size compartment of the rotatable cylinder of a rotary dyeing machine, the steps of: substantially filling the compartment of a prescribed size with a plurality of bags of dry textile articles with a dye bath resulting in the shrinkage and compacting of the articles within the bags, rotating the cylinder for displacing the bags along a generally rotary path, and applying forces to the wetted bags of textile articles to compact the bags of textile articles and reduce, effectively, the size of the compartment.
17. The method as recited in claim 16, wherein such forces are applied by centrifugal forces.
18. The method as recited in claim 16, and further including positively applying a force to the bags of textile articles during the dyeing cycle.
