Apparatus for winding on an object extending in a longitudinal direction like a line or a cable

Abstract

An apparatus for winding on an object extending in a longitudinal direction has a drum with a supporting surface extending over the periphery for support of the object to be wound on and raised portions which extend radially away from the axis of rotation of the drum at the sides or in lateral regions of the supporting surface, wherein there is provided a device for preventing the windings of the object from piling up, which device includes a shaft] having an external thread, the shaft extending transversely over the supporting surface at a small spacing over a narrow gap from the raised portions and is mounted at a component arranged laterally of the drum.

         19 . The apparatus according to  claim 18 , wherein the shaft is arranged in a peripheral region of the drum, that adjoins the feed of the object to the drum. 
     
     
         20 . The apparatus according to  claim 18 , wherein the shaft is arranged parallel to the axis of rotation of the drum. 
     
     
         21 . The apparatus according to  claim 18 , wherein the shaft, viewed in the direction of rotation of the drum at the location of the shaft and with a horizontal view of the shaft, has a left-hand thread portion in its left-hand region and a right-hand thread portion in its right-hand region. 
     
     
         22 . The apparatus according to  claim 21 , wherein the right end of the left-hand thread portion and the left end of the right-hand thread portion are connected directly together. 
     
     
         23 . The apparatus according to  claim 22 , wherein the left-hand thread portion and the right-hand thread portion are connected together in the centre of the shaft. 
     
     
         24 . The apparatus according to  claim 22 , wherein the left-hand thread portion and the right-hand thread portion are arranged in mirror-image relative to each other with respect to a plane extending at the connecting location perpendicularly to the axis of rotation of the shaft. 
     
     
         25 . The apparatus according to  claim 22 , wherein the left-hand thread portion and the right-hand thread portion are arranged displaced relative to each other through 180° about the axis of rotation with respect to a mirror-image arrangement with respect to the plane extending perpendicularly to the axis of rotation, wherein in particular the plane extends at the connecting location through a thread crest of the one thread portion and a thread groove of the other thread portion. 
     
     
         26 . The apparatus according to  claim 18 , wherein the shaft has a continuous left-hand thread or a continuous right-hand thread viewed in the direction of rotation of the drum at the location of the shaft. 
     
     
         27 . The apparatus according to  claim 18 , wherein the shaft is in the form of a hollow shaft and is mounted rotatably on a spindle held at or in the component arranged laterally of the drum. 
     
     
         28 . The apparatus according to  claim 18 , wherein at its ends the shaft has bearing journals ( 19 ) which engage into bearing mountings at or in the component arranged laterally of the drum. 
     
     
         29 . The apparatus according to  claim 18 , wherein at least one of its end regions the shaft is provided with a frustoconical enlargement which faces towards the end in question and the largest diameter of which is larger than the outside diameter of the thread of the shaft, wherein the spacing between the enlargement and the supporting surface is less than the height of the flange above the supporting surface. 
     
     
         30 . The apparatus according to  claim 18 , wherein the outside diameter of the thread of the shaft increases at least in one of its end regions in a direction towards the end face of the shaft, that adjoins the end region. 
     
     
         31 . The apparatus according to  claim 18 , wherein the component arranged laterally of the drum has a wall for mounting the shaft, said wall extending parallel to the adjoining end face of the drum. 
     
     
         32 . The apparatus according to  claim 31 , wherein the drum is mounted rotatably to the wall. 
     
     
         33 . The apparatus according to  claim 18 , wherein at least one of the raised portions arranged laterally of the supporting surface for the object to be wound on the drum is in the form of a flange which extends radially outwardly from the supporting surface over a height, wherein the shaft extends at a small spacing relative to the flange over same and the supporting surface. 
     
     
         34 . The apparatus according to  claim 33 , wherein the flange extending radially outwardly at least at one side of the supporting surface is in the form of a flange in the shape of a circular ring which extends over the entire periphery of the drum and which at its outside remote from the supporting surface forms an end region of the drum.
