Abstract: A method and apparatus are disclosed for forming a tubular yarn carrier of the type adapted to have a yarn wound thereon to form a yarn package, and which includes an inturned annular end portion which is adapted to support the carrier on an internal spindle of a winding machine. The method of forming the inturned annular end portion includes inwardly turning one end of a tubular body member and so as to cause the end to be inwardly turned about an arc of about 180.degree., and while concurrently guiding the inwardly turned end radially outwardly into contact with the inside wall surface of the tubular member. The method results in the formation of a frusto-conical end portion which essentially locks against the inside wall surface of the carrier and thus prevents the inturned end portion from opening up during use.

Abstract: The present invention is directed to an apparatus and method wherein preprinted rectangular blanks of longitudinally stretch-oriented foam sheet material are continuously formed into cylinders by a tubular forming mandrel on which the blanks are folded, seamed and thereafter transferred onto final forming mandrels. Subsequently, the blanks and the final mandrels are heated to shrink the blanks so that they assume the shape of the final forming mandrels. In forming containers, means are provided to place bottom blanks on the product mandrels prior to the loading of the cylinders thereon so as to shrink the cylinders to sidewall shapes overlying the bottom blanks. The top curl on containers such as drinking cups and food tubs is formed after shrink forming. Further, the bottom seam of the container may be reinforced by ironing after shrink forming.
