The invention relates to a warping machine (1) for a rope (3) made of a plurality of yarns (5), comprising a support structure (25), a bobbin (9) onto which said rope is warped, wherein said bobbin is mounted on the support structure for rotating around a rotational bobbin axis (R1) of the bobbin, and a pressure drum (31) rotatably mounted on the support structure for rotating around a rotational drum axis (R2) for applying pressure onto the rope warped onto the bobbin, wherein said rotational bobbin axis is supported stationary with regard to said support structure and said rotational drum axis is translationally movably mounted on the support structure so that the pressure drum follows an increasing warp thickness on the bobbin.

Apparatus used with a yarn warper or beamer to uncross yarn ends that have become crossed during a warping operation. An element shaped like a knuckle moves back and forth across a side of the yarn sheet while protruding into the path of yarn ends making up that sheet. The motion of the knuckle against the side of the yarn sheet raises each yarn slightly, then allows the yarn to return to its original position. This motion dislodges yarn ends that have become crossed and allows them to return to their proper registration in the yarn sheet. The end uncrossing device may be located either downstream or upstream from the comb assembly in a warper.

The invention relates to a warp machine for warping and spooling warp threads, particularly elastic or viscous warp threads. The warp machine according to the present invention includes a warp beam or parallel warp beam for taking up the warp thread and which is mounted to be rotationally driven about a rotary axis and which consists of a cylindrical spool element preferably having two lateral, flange-like warp beam discs. In addition, the machine is equipped with a compression element which is preferably movably mounted in an essentially radial direction to the warp beam which engages between the warp beam discs, and which presses the warp thread against the spool element. According to the present invention, the compression element is formed in two parts from two compression rollers, each of which is mounted only in the area of a frontal side so as to rotate about rotary axes that lie parallel to each other and to the rotary axis of the warp beam in such a manner that the free front side of each compression roller extends toward one of the warp beam discs, and the two compression rollers overlap in an axially central area of the warp beam by an axial length X greater than zero. In this configuration the compression element can have smaller diameter and low gyration mass.

Beam warping machine with a device for the maintenance of required yarn tension in a group of yarns (5) with rolls (7, 8; 34, 35, 36) around which said group of yarns is wound following an S-shaped path in continuous operation, said pair of rolls being driven without slippage in a operative position (51), whereby brakes (30) acting upon the warp beam (3) are activated when the machine is stopped while at the same time one of the rolls (7,35) is swivelled radially out of its operative position (51) and away from the yarn group (5), whereby the swivelling motion ends in a slippage position (37) which can be selectively adjusted as to degree of swivelling by means of an adjustment link (39), whereby the yarns in the area of the rolls (7, 8; 34, 35,36) braked with the displacement assumes a path allowing for slippage of the yarn group (5) against the rolls (7, 8; 35, 36), said path being straighter than the S-shape.
