Definitions

  • This invention relates to improved mandrels for spoolers of winder heads.
  • spoolers are known for producing conical cross-wound packages which afford the advantage that the thread may be drawn off therefrom in an axial direction without excessive ballooning.
  • Such spoolers comprise a winder head having a hollowcone mandrel which serves as package-and-core holder or mount and, in known constructions, has longitudinal slots extending from the cone base to form resilient leaves intended to clampedly engage a package core slidably mounted on said mandrel.
  • the main object of my present invention is to overcome the said disadvantage by making the hollow-cone mandrel of a resilient plastic.
  • the mandrel preferably is made of a thermoplastic material possessing the requisite resilience, breaking strength and resistance to abra- S1011.
  • a mandrel made of plastic has the further advantages of smaller inertia and lower manufacturing costs.
  • Fig. 1 shows the winder head in side view
  • Fig. 2 is a top plan view of a portion of Fig. 1, and
  • Fig. 3 shows a portion of the cone mandrel in section on the line III-III of Fig. 2.
  • the winder head illustrated comprises a package-andcore holder mandrel which has the shape of a hollowcone and is supported on a shaft 11 by its smaller end.
  • the shaft 11 is rotatably mounted on a bracket 12 by means of ball bearings housed inside the mandrel 10, as known in prior art.
  • the mandrel 10 on its circumference is provided with a plurality of equidistant longitudinal slots 13 which extend from the cone base and form leaves14 on the mandrel 10.
  • the said leaves are resilient and may be slightly spread outwardly, in a manner known per se, by means of an element, not shown in the drawing, which is disposed inside the hollow cone, in order to clampedly engage a bobbin core (not shown) slidably mounted on the mandrel 10.
  • a bobbin core (not shown) slidably mounted on the mandrel 10.
  • the latter is provided with a plurality of circumferential ribs 15 which are of sawtooth-shape in profile and extend over a portion addition of softeners or plasticizers being possible.
  • the cone base furthermore, is provided with an outwardly flared circumferential rim 16 which serves as stop for the bobbin core to be mounted on the mandrel 10.
  • the mandrel 10 is made of an elastically resilient plastic which enables the leaves 14 to resiliently yield towards and away from the shaft 11 and affords a high breaking strength when subjected to continued bending stresses.
  • a thermoplastic material may be used, which affords the further advantage of high resistance against abrasion, so that practically no wear of the mandrel or holder 10 is to be feared.
  • the material of the mandrel 10 may consist, partly or entirely, of a polyamide, polyaminochloride, polystyrene or of mixed polymerization. It, however, also could be made, partly or entirely, of cellulose acetate or cellu lose-acetate butyrate. In any case it is possible to make the mandrel 10 of a mixture of different plastics, the
  • the mandrel 10 suitably is formed by die casting.
  • the leaves 14 are stiffened on their free ends by longitudinal ribs 17 which also are engaged by the element for spreading the leaves 14.
  • longitudinal ribs 17 are disposed immediately adjacent the slots 13 and are of a thickness substantially equal to that of the hollow cone.
  • the winder head described has fully met the requirements of practical application.
  • the leaves 14 may be spread far outwardly without risk of breaking, and they resume their initial poslitions under the action of the resilience of the materia While the preferred embodiment of the invention has been shown and herein described, it will be understood that the same is capable of embodiment without departure from the general scope and spirit of the invention as defined in the claims.
  • a hollow cone which serves as package-and-core mandrel and provided with longitudinal slots extending from the base of said cone for the purpose of forming resilient leaves between said slots and adapted to clampedly engage a bobbin core slidably mounted thereon, said mandrel leaves being stiffened on their free ends by longitudinal ribs disposed on the inside of said leaves, said mandrel being made of resilient plastic material.
