Device with a double series of sinkers and double sinkers housing for

Abstract

A device for forming, terry knit with a terry yarn and a base yarn for the base fabric. A needle cylinder is provided including a plurality of needles, driven for reciprocating motion. A plurality of sinkers with a high nose for the terry yarn and a plurality of sinkers with a low nose for the base yarn are provided. A high yarn guide for the terry yarn, is provided at a high yarn guide level and a lower yarn guide for the base yarn is provided at a lower level than a level of a surface of the high-nosed sinkers. A fixed annular sinkers housing is provided including a fixed cam profile to control radial movement of the high-nosed sinkers. The cam profile has an area of centrifugal retraction substantially symmetrical with respect to a feeding position of the high yarn guide and the lower yarn guide. An angularly mobile annular sinkers housing is provided for controlling radial movement of the low-nosed sinkers. The angularly mobile annular sinkers housing included a fixed cam having an apex pointing outwardly with respect to the needle cylinder. The angularly mobile annular sinkers housing alternates with each reversal of motion of the needle cylinder such that the fixed cam moves between a first position and a second position. The first position and the second position are substantially symmetrical, with respect to the cam profile, on opposite sides of the high yarn guide and the lower yarn guide for centrifugally retracting low-nosed sinkers in proximity to a stitch forming area, after the feeding position of the high yarn guide and the lower yarn guide, upon each reversal of motion of said needle cylinder.
