Abstract
The twin-cylinder circular knitting machine with knitted fabric tensioning device having members for retaining the fabric proximate to a knitting forming region. A first fluid-activated piston is accommodated in the upper needle cylinder and is provided with a hollow stem which is open at its ends. The lower end of the stem is engageable, by means of the sliding of the piston parallel to the axis of the needle cylinders, with the knitted fabric being formed in order to apply tension thereto. The retention members have dimensions for allowing the stem to slide outside of the retention members. The tensioning device also has an auxiliary actuation piston which acts on the piston to achieve its descent at a controlled rate at least until the lower end of the stem of the piston makes contact with the fabric in the region comprised between the retention members and the knitting forming region.
