US 3,995,786 A · Intermediate yarn feeding and control device

Abstract

There is disclosed an intermediate yarn feeding and control device having a storage member adapted to have yarn wound thereabout adjacent one end thereof to form yarn windings which advance toward the other end thereof. Yarn guide means located adjacent the other end of the storage member is adapted to guide the yarn, selectively, into one of two separate paths of yarn travel. A restraining element restrains the yarn withdrawal to a preselected rate when the yarn is guided through one of the paths but is clear of the yarn travel when the yarn is guided through the other of said paths for permitting the yarn to be withdrawn from the storage member at any desired rate. The yarn guide means includes a plurality of outwardly extending resilient fingers whose free ends support an outer ring so that when the withdrawn yarn is guided through the one path which is inwardly of the outer ring, it flexes successive resilient fingers which impart thereto a preselected tension.

Dependent claims

In a yarn feeding device wherein yarn windings are formed on a storage member adjacent one end thereof and the yarn is thereafter withdrawn therefrom adjacent the other end thereof, means for imparting preselected tension to the yarn being withdrawn comprising,

a. a plurality of resilient fingers carried by support means therefor disposed adjacent said other end of said storage member, said fingers extending outwardly of said support means and projecting beyond the outer periphery of said storage member,
b. an outer ring having an inner wall provided with a peripheral seat for receiving the outermost portions of said resilient fingers which constitute the means of support for said outer ring, said outermost portions of said resilient fingers, when the resilient fingers are in relaxed condition, collectively defining a circle whose diameter is greater than the diameter of said peripheral seat therefor,
c. the withdrawn yarn being passed between said outer ring and the outer periphery of said storage member whereby as the yarn is withdrawn it flexes successive resilient fingers which impart thereto a preselected tension.

A yarn control device for controlling the feeding of yarn to a textile machine comprising,

a. yarn storage means,
b. means co-acting with said yarn storage means for causing yarn to be wound on said yarn storage member adjacent one end thereof to form a plurality of windings which advance toward the other end of said storage means,
c. yarn guide means disposed adjacent said other end of said storage means for guiding the yarn being withdrawn from the storage means, said yarn guide means having means defining two separate selective paths for the yarn travel, and
d. said co-acting means including a portion separate and distinct from said yarn guide means which restrains the yarn withdrawal to a preselected rate when said yarn is guided through one of said guide means paths and which portion is clear of said yarn withdrawal travel when said yarn is guided through the other of said guide means paths for permitting yarn to be axially withdrawn from said storage member at any desired rate.

A yarn control device for controlling the feeding of yarn to a textile machine comprising:

a. yarn storage means,
b. means co-acting with said yarn storage means for causing yarn to be wound on said yarn storage means adjacent one end thereof to form a plurality of windings which advance toward the other end of said storage means,
c. said storage means having an internal passage through which the yarn wound onto said storage means travels as it is withdrawn from the storage means adjacent said other end thereof,
d. yarn guide means disposed adjacent said other end of said storage means for guiding the yarn into said internal passage, said yarn guide means having means defining two separate selective paths for the yarn travel, and
e. said co-acting means including a portion separate and distinct from said yarn guide means which restrains the yarn withdrawal to a preselected rate when said yarn is guided through one of said guide means paths and which portion is clear of said yarn withdrawal travel when said yarn is guided through the other of said guide means paths for permitting yarn to be axially withdrawn from said storage means at any desired rate.
