Abstract
Abstract Hosiery from a knitting machine is placed on a hollow tubular form while still in a string, the first in-line hose is everted or turned by suction through the open end of the form, the hose is separated from the string and is pulled off the open end of the form and deposited in everted form at a stacking station. The portion of the hose adjacent the open end of the form is doubled over and the pulling-off operation is performed by a pair of grasping fingers engaging the doubled over portion. The separating operation is preferably performed simultaneously with the pulling-off operation by breaking a knitted connector ring attaching the hose to the string. Initially, pulling the hose on the form over the open end and bunching the string on the form is facilitated by inducing egress of air during the pulling-on operation. A rotating roller may also be utilized to facilitate this loading operation. The grasping fingers engage a flattened side of the form to grip the doubled over portion of the hose and a spring loaded over-center linkage operates the fingers. First and second stops actuate the linkage to grip and release, respectively, and first and second bumpers assure operation by momentum action of the linkage means at the extreme travel positions.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
106 words
A method of handling hosiery comprising the steps of: placing a string of hose on a hollow tubular form, inducing ingress of air through the open end of said form, moving the end of said string on said form over said open end to extend the first in-line hose into said form thereby everting the hose, holding a portion of said hose adjacent said open end of said form, separating said hose from the remaining hosiery on the string, and pulling said portion of said hose to remove the hose off the open end of said form and move the same along a predetermined delivery path.
Claim 2
Independent Claim
106 words
A method of handling hosiery comprising the steps of: placing a string of hose on a hollow tubular form, inducing ingress of air through the open end of said form, moving the end of said string on said form over said open end to extend the first in-line hose into said form thereby everting the hose, holding a portion of said hose adjacent said open end of said form, separating said hose from the remaining hosiery on the string, and pulling said portion of said hose to remove the hose off the open end of said form and move the same along a predetermined delivery path.
Claim 3
Dependent Claim
46 words
The method of claim 1 wherein the step of moving the string of hose on the form comprises: positioning the hose over the open end of the form so that said portion is doubled-over on itself, and the pulling-off operation is performed on the doubled-over portion.
Claim 4
Dependent Claim
19 words
The method of claim 2 wherein the doubled-over portion of the hose that is pulled-off is the welt end.
Claim 5
Dependent Claim
18 words
The method of claim 1 wherein the step of separating said hose is performed during the pulling-off operation.
Claim 6
Dependent Claim
23 words
The method of claim 4 wherein the separating operation is performed by breaking a knitted connector ring by the force exerted during pulling-off.
Claim 7
Dependent Claim
39 words
The method of claim 1 wherein is further provided the step of: delivering said hose in the same motion as the pulling-off step along said delivery path to a stacking station, and releasing the hose at the stacking station.
Claim 8
Dependent Claim
30 words
The method of claim 1 wherein the string is placed on said form by pulling-on over the open end and bunching the string toward the opposite end of the form.
Claim 9
Dependent Claim
37 words
The method of claim 7 wherein is further provided the step of: inducing egress of air from the open end of said form during pulling-off of the string thereby preopening the string to reduce the frictional resistance.
Claim 10
Dependent Claim
38 words
The method of claim 8 wherein the pulling-on operation includes applying an endless moving surface to the outside of said string, the inside of said string being supported in the area of said moving surface by said form.
Claim 11
Dependent Claim
98 words
A hosiery handling apparatus for turning, separating and stacking hose from a string comprising: a hollow tubular form for receiving the hosiery string, said form having an open mouth forming one end, a source of vacuum connected to the opposite end of said form to evert the first in-line hose through the mouth and into the form, means for sepArating said hose from said string, and means for pulling said hose off the open end of said form after eversion, whereby the hose is separated from said string and delivered away from said form along a predetermined path.
Claim 12
Dependent Claim
98 words
A hosiery handling apparatus for turning, separating and stacking hose from a string comprising: a hollow tubular form for receiving the hosiery string, said form having an open mouth forming one end, a source of vacuum connected to the opposite end of said form to evert the first in-line hose through the mouth and into the form, means for sepArating said hose from said string, and means for pulling said hose off the open end of said form after eversion, whereby the hose is separated from said string and delivered away from said form along a predetermined path.
Claim 13
Dependent Claim
98 words
A hosiery handling apparatus for turning, separating and stacking hose from a string comprising: a hollow tubular form for receiving the hosiery string, said form having an open mouth forming one end, a source of vacuum connected to the opposite end of said form to evert the first in-line hose through the mouth and into the form, means for sepArating said hose from said string, and means for pulling said hose off the open end of said form after eversion, whereby the hose is separated from said string and delivered away from said form along a predetermined path.
