<p>The disclosure relates to methods and apparatus for finishing tubular knitted fabric involving the steps of laterally distending the fabric to flat, two-layer form by passing it over a spreader frame, and discharging the fabric from the spreader frame into a pair of opposed calendering rolls. Improved arrangements are provided for engaging the tubular fabric, across its fully spread width, above and below the spreader, for independently advancing or retarding the respective layers of the fabric in order to bring them into proper alignment. The improved arrangements include a thin, flat contact plate, incorporated into the spreader frame structure, which provides a contact support from the fabric, enabling it to be drivingly engaged by independently driven contact rolls. The structure enables the fabric to be adjusted substantially across its full width, reducing to a practicable minimum areas at the extreme edges of the fabric tube that are not under positive control during the reducing to a practicable minimum areas at the extreme edges of the fabric tube that are not under positive control during the adjustment stage. The apparatus also includes and improved entry guard arrangement, which facilitates the machine operator's attendance to the equipment and process while improving working conditions from a safety standpoint.</p> |
