Abstract: A machine makes nails having a star-shaped transverse cross-section by sequentially feeding conventional nails into a form roller station defined by a plurality of form rollers that are radially arrayed with respect to a centerline of the nails. Circumferentially spaced notches formed about the periphery of each form roller engage the heads of the conventional nails as the form rollers rotate and pull the nails into forming relation with the form rollers. The notches also prevent formation of the nail heads. A plurality of circumferentially spaced concavities formed in the form rollers prevents forming of the work-hardened points of the nails. The nails are sequentially delivered from a bowl feeder to an indexer that inverts the nails. A pair of rotatably mounted augers transfer the nails from the indexer to a nail-gripping device that holds each nail until its head is engaged by the nail-engaging notch in each of the form rollers. The form rollers are rotated by a gear train that begins with a ring gear rotated by a motor, and the gear train enables adjustment of the rotational phase of the form rollers so that they may be maintained in rotational phase with one another.

Abstract translation: 机器通过将常规指甲顺序地供给到由相对于指甲的中心线径向排列的多个成形辊限定的成型辊站，使具有星形横截面的指甲。 形成在每个成形辊的周边周围的周向隔开的凹口与成形辊一起旋转并将钉子与成形辊成形成关系，与常规钉子的头部接合。 切口也防止钉头形成。 形成在成形辊中的多个周向间隔开的凹部防止了钉子的加工硬化点的形成。 钉子从碗式送料器依次递送到反转钉子的分度器。 一对可旋转安装的螺旋推运器将指甲从分度器传送到夹持每个指甲的指甲夹持装置，直到其头部与每个成型辊中的指甲接合凹槽接合。 成形辊由齿轮组转动，该齿轮系以由马达旋转的齿圈开始，并且齿轮系能够调节成型辊的旋转相位，使得它们可以彼此保持旋转相位。
