device allargatore of tubular knitted fabrics, especially for calendering decatrici and termofissatrici

摘要

a device allargatore for calendering decatrici and termofissatrici.particularly to extend from the inside of a tubular knitted fabric (t) that is made to advance flattened with opposite sides (t, t ') and the lateral edges (b, b').includes a pair of arms expanders (2, 3) independent, substantially parallel to the direction of advance (f) of the fabric, a pair of supports (4).5) to support the arms and carry the fabric.means (6, 8) for controlling the relative distance in the direction of enlargement media substantially perpendicular to that of progress to vary the width of the fabric.at least one driven wheel (9 - 11, 12 to 14) which each support designed to engage with a respective pair of rollers mounted on the respective arm girevolmente crazy.the wheels and the rollers with axes substantially parallel to the surfaces of engagement and enlargement plan controsagomate that interact only with the opposite sides of the tissue (t,t ") interposed along areas discoste edges (b, b '). the device avoids some overlapping in terms of time and deformity of the plot.
