A tubular knitted fabric is guided over a first rotatably arranged system of squeezing roller pairs and is then squeezed out, during a simultaneous continuous pulling off of the fabric, by a second system of squeezing rollers cooperating with the first system. The creation of edge markings is thereby completely prevented. An apparatus for the squeezing out process has a first system of rotatably arranged squeezing roller pairs which is held inside of the tubular fabric front the outside thereof and which has an adjustable outer periphery and a second system of rotatably arranged squeezing rollers also held on the outside of the tubular fabric. The second system is adapted to the periphery of the first system of squeezing roller pairs. Both systems cooperate with each other.
An apparatus for spreading tubular fabric, thereby avoiding edge markings in said tubular fabric which has been drenched in refining solution, comprising a frame structure having a central longitudinal axis, a first system of rotatable first squeezing rollers (25) to be positioned inside said tubular fabric, said first squeezing rollers (25) being positioned relative to each other to define a spreader configuration for said tubular fabric, said spreader configuration having a spreader periphery, a central telescoping carrier (19) supported in said frame structure, said central telescoping carrier comprising upper and lower supports (20, 21) carrying said first squeezing rollers (25), said central telescoping carrier permitting adjusting said first squeezing rollers (25) radially inwardly and radially outwardly relative to said central longitudinal axis for decreasing and increasing said spreader periphery respectively, a second system of rotatable second squeezing rollers (27) mounted in said frame structure to be positioned outside said tubular fabric for pressing said rotatable second squeezing rollers (27) against said rotatable first squeezing rollers (25), means (39) in said frame structure connected to said rotatable system of second squeezing rollers (27) for adjusting a position of said rotatable second squeezing rollers (27) radially relative to said first rotatable system of squeezing rollers (25) to influence a squeezing gap between said rotatable first and second squeezing rollers (25, 27), said means for adjusting said position of said second squeezing rollers comprising a plurality of pivoted levers (38, 38') carrying said second squeezing rollers (27) and an arrangement (39) for operating said pivoted levers, thereby positioning said second squeezing rollers (27) relative to said first squeezing rollers (25), and a drive device (40, 43, 44, 45, 46, 47, 48, 49) operatively connected to said second system of rotatable second squeezing rollers (27) for rotating said second system, and wherein said first and second squeezing rollers (25 and 27) are held in a common slanted position at an angle .alpha. relative to said central longitudinal axis.
