The disclosure is directed to apparatus for folding processed fabric. It is particularly useful for, although not necessarily limited to, the folding of processed tubular knitted fabric. The folder is positioned at the discharge end of a fabric processing line, and is arranged to convey the fabric, moving at relatively high speed, to a discharge point directly above a folding platform. The fabric is then directed downward between guides, which oscillate back and forth over the folding platform, to lay the fabric in successive layers of substantially uniform length. A significant feature of the invention relates to the construction of the oscillating guide member to accommodate passage of the fabric, moving downward at relatively high speeds while the oscillating guide is moving forward and backward at relatively high speed. The guide is constructed of opposed, relatively large panels, extending across the full width of the fabric and forming a gradually converging path, leading to discharge rollers at the lower end of the folding guide. The panels are air permeable over their entire working areas, so as to provide for a general but low velocity flow of air outward from the face of the panel.

The invention relates to methods for increasing the production over a given period of time of the finishing of tubular knitted fabric and to the semi-automatic control of the batching and doffing thereof. Included herewith are methods for enhancing the speed of steam treatment of such fabrics by increasing impregnation thereof with steam boxes enclosed in a steam chamber, and methods for limiting roll pressure during stretching of the fabric to reduce marking. Also included is a semi-automatic batching and doffing device incorporating controls for sequentially inserting an empty mandrel, cutting, and positively controlling the cut loose end of fabric web for engagement with the new mandrel, with such sequence being initiated by removal of the previous wound-up roll. The cutter and the air jet control for the cut loose end of fabric are movable into and out of engagement with the web path of movement for enhancing the positioning thereof for action upon the web.

The disclosure relates to a mechanism for high speed horizontal folding of fabrics, such as tubular knitted fabrics, enabling the fabric to be folded at greatly increased linear speed in relation to the prior art. The folder apparatus includes horizontally reciprocating downfeed rollers which receive the incoming fabric and propel it downwardly, while guiding the fabric horizontally to lay it in back and forth folds of substantially uniform length. Means are provided for reciprocating the downfeed rollers horizontally at high speed during the folding operation. Means are also provided for continuously rotating the downfeed rollers, independently of the horizontal reciprocating motion thereof, for directing the incoming fabric downward toward the accumulating fold stack. Reciprocating weight is held at a minimum by providing a novel external drive for the downfeed rollers, which are operative to provide a constant rate of downfeed of the fabric in any horizontal position of the downfeed rollers. The invention also provides an optimum geometrical condition for the incoming fabric web, for minimizing the effects of air inertia and resistance on the rapidly oscillating fabric web.

A high production steamer for tubular knitted fabrics or the like which comprises means for distending and conveying the fabric along a predetermined, generally horizontal processing plane and a pair of steam boxes mounted in opposed relation, one above and one below the processing plane. The steam boxes are of a heretofore known dripless construction which includes discharge openings extending across the width of the fabric and arranged to direct steam toward the upper and lower faces of the fabric. According to the invention, a novel steam confining means is provided to confine the discharged steam to a limited region closely surrounding the fabric. The confining means comprises a chamber formed by wall-forming members associated with the discharge sides of the steam boxes and the end plates of the opposed steam boxes which are arranged in a contacting relation along the sides of the path of conveyance for the fabric. To advantage, the steam confining means will facilitate an effective steam penetration of the fabric in a relatively short time period. Means are also provided to heat the upper regions of the steam confining means to prevent condensation of the discharged steam above the processing plane.

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 disclosure is directed to apparatus for processing of tubular knitted fabric, including an internal flat spreader and width-adjustable edge drives, typically used in connection with other processing apparatus, such as calendars, padding equipment, compressive shrinking stations, etc. The apparatus utilizes a pre-loaded, resiliently biased spreader frame which, within its operating limits, presses outwardly against adjustably movable, opposed edge drive rolls. The spreader frame, which is positioned internally of the moving fabric tube during processing operations, is capable of in-process width adjustments, without either stopping the processing line or damaging the fabric. Width adjustment of the internal spreader frame may be accomplished from a remote operator station. Moreover, the apparatus may incorporate edge-sensing means operative automatically to adjust the width of the spreader to maintain uniformity of width in the processed fabric.

The disclosure is directed to an improved stop mechanism for controlling edge drives of fabric spreaders, in the processing of tubular knitted fabrics. A combination spreader and propeller mechanism, consisting of a frame and fabric engaging belts, is received internally of a section of tubular knitted fabric, in order to distend the fabric laterally during or prior to certain processing operations. The fabric engaging belts are driven by means of edge drive rolls, which externally engage the fabric at its opposite edges and drive the belts through the intervening fabric layer. Occasionally, the fabric may jam on the spreader frame such that, with continued fabric movement, the spreader frame tends to become dislodged from the edge drive rolls. Various photoelectric and mechanical arrangements have been proposed for stopping the equipment at such times, in order to prevent damage to the spreader frame and/or other parts of the equipment. The present disclosure relates specifically to a new and improved magnetic proximity arrangement for stopping the processing equipment in response to dislodgement of the spreader frame from its normal position.
