Abstract: A steel-pipe coating process and an apparatus therefor, in which molten resin is extruded through a cross-head die connected to an extruder, into a tubular shape, in a manner to cover or coat the surface of a steel pipe. In this apparatus, a resin outlet in the extruder is communicated through the medium of a resin guide member with a resin inlet of the cross head die. The extruder is secured to a fixed frame, while the cross head die is supported by the fixed frame in a reciprocating manner through the medium of a reciprocating drive member within a given stroke in the direction of the steel pipe being fed. Thus, when the cross head die is reciprocated by means of the reciprocating drive member, the relative speed of the steel pipe being fed to the cross head die being reciprocated may be intermittently varied, whereby the amount of resin being extruded through a cylindrical outlet of the cross head die around the surface of the steel pipe may be intermittently varied.

Abstract: A method and apparatus for treating the terminal end portion of a wire-like object within a wire-like object take-up apparatus is disclosed as including main and auxiliary terminal treating covers, the covers being moved axially toward each other and in surrounding relation with respect to a bobbin upon which the wire-like object is wound so as to define therebetween an overlapped position within which a terminal end receiving chamber or spacing is defined. In this manner, the terminal end is encased and upon severance of the same, the terminal end cannot fly about in a random manner, or be additionally severed and shredded, whereby damage thereto, as well as to the take-up apparatus and wound object, and the operating personnel, is effectively prevented.

Abstract: A device for ensuring the smooth shifting of a strand from a full reel to an empty reel in a strand winding machine including improvements in the snaggers provided on the wheels which are rotating with the two associated reels arranged parallel to each other. The snaggers are provided on each wheel and are supported by a shaft parallel to the central axis of revolution of the wheel such that the snaggers are rotatable about the shaft. The centroids of the snaggers are displaced from the pivot of the snagger itself, that is, positioned on that side of the pivot which is opposite from the pointed end of the snagger. Thus, the snagger can securely grip and hold the strand during rotation of the wheel and can release the strand when the wheel comes to rest.
