Abstract: The invention relates to a method and a device for correcting the bending of a shaft (2), an axle or another carrier resting with both ends upon a pair of bearing elements (6, 7). The carrier bends under its own weight and/or additional loading and/or due to forces applied on the bearing elements. Said bearing elements are submitted to a bending counterforce (4) produced using the carrier weight and/or additional loading and/or forces applied.

Abstract: An apparatus and method for winding a yarn in a wild winding onto a package, includes a reversing screwthread shaft (1) having an endless screwthread groove (2) and a yarn guide which produces in particular a creep stroke motion. The reversing screwthread shaft (1) has a turns number which establishes a double stroke having a forward stroke (3) and a reverse stroke (4) and which includes a mixed number and whose integral component is .gtoreq.2 and the balance of which represents a true fraction, and has on each side a plurality of reversals (5) which in particular are arranged in axially displaced relationship with each other. A half turns number which establishes a forward stroke (3) and a half turns number which establishes the associated reverse stroke (4) are the same.

Abstract: A traversing yarn guide (1) for winding machines with a reversing screwthread shaft (8) having an endless screwthread groove (14), including a main body (2) which is rectilinearly reciprocably guided on two guide rails (5, 6) and which on the one hand carries a yarn guide (3) and which on the other hand has a guide projection (12) projecting into the screwthread groove (14) of the reversing screwthread shaft (8). The traversing yarn guide further comprises a shuttle (17) which is mounted pivotably on the main body (2) and which engages into the screwthread groove (14) of the reversing screwthread shaft (8). The guide projection (12) of the main body (2) is in the form of a cylindrical pin (13) which is arranged co-axially with respect to the axis (11) of the main body (2) and which is adapted with slight clearance to the cross-sectional shape of the screwthread groove (14).

Abstract: A method for cross-winding of thread-like or band-like winding material on winders is described for the production of bobbins wound up in cross-winding with random winding or precision cross winding. The winding material is traversed by a slit drum (1) comprising a slit (5) and is wound up to a bobbin (18). The winding material is traversed by a slit drum (1) comprising at least three parts (2, 3, 2) forming the slit (5) and at least one crossing point (6). The winding material entering the slit drum (1) is guided by an auxiliary apparatus (10), which forces an additional motion to the winding material while passing each crossing point (6) of the slit (5) of the slit drum (1) to maintain the corresponding traversing direction (8).

Abstract: A method and apparatus for the reeling of a ribbon-like or filamentary material fed to a bobbin winder and wound up in cross winding with precision winding provides for the integrals of the angular velocity (impulses) of the bobbin to be recorded by a first sensor and the integrals of the angular velocity of the drive for the traversing thread guide by a second sensor, the sums of the integrals of the angular velocity to be compared with each other and the drive for the traversing thread guide to be regulated depending on this. The impulses of the first sensor are added in a first allocated counter and the impulses of the second sensor in a second allocated counter during the entire winding operation.
