  • Patent number: 5722464
    Abstract: The weaving of terry cloth is improved by preventing slackening of the warp threads during beat-up. The warp threads are kept in contact with a warp tensioning faller roller (8) at all times. For this purpose the faller roller (8) is eccentrically mounted and biased by a spring (46) retraction force applied through a control lever (48). The force of the spring (46) is in balance with the tension on the warp threads (4), whereby the spring (46) causes a warp length compensation during shed formation. A piston rod (52A) of a piston cylinder drive (52) acts on the control lever (48) of the faller roller (8). By pressurizing the cylinder (52), the faller roller (8) is tilted about an eccentrically mounted bearing shaft (14) and a rated pile warp thread length (54) is delivered or fed, without the pile warp threads (4) lifting away from the faller roller (8).
