Warp beam with paddling reinforced on the inside

United Glanzstoff-Fabriken AG Wuppertal-Elberfeld

The invention relates to a warp beam made of light metal, consisting of a tubular middle part and two with this in a known manner Way connected splashing.

It is well known that the flawless condition of the inner flange surfaces plays a role Warp beams, partial warp beams and the like play an important role in the run-off of the warped threads. In general the warp beams with flanges consist of a light metal alloy, the latter mostly being cast or drop forged. Their inner surfaces have been treated according to a special polishing process, since the polishing quality had to be very high. It has however, it is shown that they are particularly affected by transport repeatedly damaged what before any further use reworking of the surfaces required.

Although attempts have been made by painting, anodizing or other similar Treatment methods to protect the inner surfaces against abrasion and corrosion and also to make them scratch-resistant to a certain extent. However, this could not prevent the surfaces from remaining in particular remained highly sensitive to sudden impacts, because this is not the hard skin, but the strength of the

Subsoil is crucial. Besides, she was by such means did not achieve scratch resistance significantly and could cause scratch damage not prevent. Apart from the revision of the damaged warp beams was very labor-intensive and time-consuming, there were scratches that were barely visible when examined superficially frequent process difficulties with damage to the edge threads.

The object of the invention is now to make the paddling surfaces scratch-resistant and to make it insensitive to impact, without thereby reducing the weight savings achieved through the use of light metal would be significantly impaired. This is done using a warp beam made of light metal, consisting of a tubular central part and two splashes connected to this in a known manner achieves that the paddling inner sides each with a steel disk preferably provided with a scratch-resistant layer with high tensile strength are disguised. The scratch resistance can, for example can be achieved by a hard chrome layer. It turned out to be that even a sheet steel lining with a thickness of 0.5 to 0.8 mm is sufficient to deal with a large part of the damage that occurs to avoid. Various options have been found for attaching the lining. It has proven to be most expedient proved to be glued in with a metal adhesive known per se; with a correspondingly rigid design of the steel disc However, it also means with it by gluing, soldering or smoldering - sen feat connected bolts and matching holes in the light metal flange be tightened.

The invention is explained in more detail with reference to the accompanying drawing.

The sectional beam of the invention consists in a customary per se catfish from the tube 1 and the flanges 2, which are at Z> connected, for example by threaded to the tube and bonded. The flange inner sides are covered with a respective annular steel sheet which extends with its inside diameter to the hub 6 to the flanges 2 'during the AuQendurchmesser by a small 1st smaller than the outer boundary 4 of the splash. 2

FIGS. 2 to 4 show other embodiments of the annular sheet steel linings for the inside of the flange. Thus, FIG. 2 shows a form of liner which generally corresponds to that of FIG. 1 in terms of arrangement and internal diameter; However, the outer edge 8 of the circular ring disc is bent over so that it fits exactly onto the outer boundary 4 of the flanges 2. Like the lining sheets 5 shown in Fig. 1, the sheet 7 can also be glued in with a known metal adhesive, however, due to the stiffening by the edge 8, it is also possible to zen the disc 7 by means (dashed lines ) Bol zen 9f which expediently with the support side of the sheet metal are firmly connected «must be screwed tight.

A further embodiment is shown in Fig. 3. Here / a recess 13 has been made in the inside of the planschins with the thickness of the plates serving as the lining, into which a recess 13 is glued as a circular ring disk 10.

However, this does not exhaust the various oestalfcungsmögliohkeiten for the lining sheets ο For example, the sheet metal can, with a corresponding protuberance, lie against the hub of the flange, which has a diameter of twice the thickness of the sheet metal, and reach up to the abutting edge 3. The fastening of the lining sheets on the inside of the paddling is not of decisive importance! any type of fastening known per se can be used which guarantees tight joints and thus eliminates the risk of the threads to be wound onto the warp structure being damaged when they run off. Ale particularly advantageous bonding has proved to be, with known metal adhesives were used.
