A self-threading spool or core for a moving web or strip in which the web or strip is guided onto the periphery of a supported frame for rotation about a horizontal axis by freely flexible guide means anchored at one end to the frame and extending from said anchored end generally tangentially to the underside of the core periphery and then up and over said periphery to be held by gravity in partially encircling contact therewith or with the web being wound, the guide means defines with the periphery of said core a nip into which the leading edge of a web travelling between the core and flexible means is directed into winding engagement with the core. When a sufficient number of coils has been collected on the core, the flexible means slides free of the core to an out-of-the-way position beneath the core.
A device for coiling a moving web or strip onto a rotating core, which device comprises a frame, core support means carried by said frame upon which said core may be positioned for rotation about a horizontal axis, means for imparting rotation to said supported core, freely flexible means anchored at one end to said frame, said flexible means extending from said anchored end generally tangentially to the underside of the core periphery and then up and over said periphery to be held by gravity in partially encircling contact therewith or with the web being wound, thereby defining with the periphery of said core a nip into which the leading edge of a web travelling between said core and said flexible means is directed for winding engagement with said core.
