Title: Method of forming graded shade band on substrate
IPC: B05D1/04
Filed: 1978-09-16
Abstract: A method of forming a colored shade band along an outer edge portion of a surface of a nonconductive substrate, said band having a maximum intensity along its outer edge and a decreasing intensity adjacent the inner edge of said band, comprising supporting a grounded shield of electroconductive material adjacent said substrate with an edge of said shield approximately aligned with said inner edge of said portion of said substrate to which said band is to be applied, electrostatically spraying a dye composition toward said outer edge portion of said substrate and simultaneously applying a non- reactive fluid between said grounded shield and said substrate surface toward said outer edge portion of said substrate. Prior to the present invention, a need existed to take advantage of the higher speed of electrostatic coating to produce a colored band having a desired pattern of intensity free of disturbing optical patterns on a substrate.

Title: Knitting of elasticated hosiery tops on a double cylinder knitting machine
IPC: D04B1/18
Filed: 1981-10-09
Abstract: Initially, the needles of both cylinders of a double cylinder knitting machine are used to knit a preliminary course 12 of ground yarn supplied from a first feed of the machine. A roll welt is then knitted by holding loops of the ground yarn using the needles of one cylinder while using the needles of the other cylinder to knit alternate courses of ground yarn G from the first feed and elastic or elastomeric yarn E2 from a second feed. Following this, an elasticated band is knitted by repeatedly using the needles of both cylinders to knit a course of ground yarn G from the first feed, and using the needles of said one cylinder to knit a course of elastic or elastomeric yarn E2 from the second feed while floating the needles of said other cylinder. As an alternative, the latter course can be knitted using elastic or elastomeric yarn from a third feed. In a further alternative arrangement, an additional course of elastic or elastomeric yarn is knitted in between each course of the yarn E2 in the elasticated band and the succeeding course of ground yarn G, either using the needles of both cylinders or using the needles of said other cylinder while floating the needles of said one cylinder.
