Abstract
The disclosure relates to an apparatus for steam processing tubular knitted fabric, as in a spreading or calendering operation. The steamer apparatus of the invention is characterized by its ability effectively to impart steam to the fabric at much higher rates than has been possible heretofore, consistent with satisfactory quality. Since the steaming of the fabric heretofore has constituted a limiting or bottleneck stage of calendering or similar processing operations, the ability of the new steaming device to increase the effective rate of steam application can be translated directly into higher production rates in the fabric processing operation as a whole. The new steaming apparatus includes a pair of dripless steam boxes of heretofore known construction arranged above and below the plane of the fabric in a manner well known per se. According to the invention, however, these steam boxes are closely embraced and enclosed by a steam chamber housing, which momentarily confines the billowing steam in the immediate vicinity of the fabric surface. Steam is discharged toward the fabric in high velocity jets which are effectively continuous across the width of the fabric. The jets are …
