Abstract
Abstract The slitting and seaming together of hosiery blanks for producing panty hose is carried out by a single operator and during the usual everting, inspecting and toe seaming operation. The hosiery blanks are slit as they are drawn onto a tubular hosiery form and the upper end engages a heated wire slitter supported on one side of the tubular form and a predetermined distance from the open free end of the form. The heated wire slitter is supported between spaced guide plates which aid in directing the panty forming end portion of the hosiery blanks into engagement with the heated wire slitter.

Claim 1
Independent Claim
124 words
An apparatus for everting, inspecting and slitting tubular panty hose blanks, said apparatus comprising a. an elongate tubular form having an open free end, b. means associated with the other end of said tubular form for drawing air inwardly through the open free end and along the length of said tubular form to create suction currents therein, and c. a heated wire slitter supported on one side of said tubular form and a predetermined distance from the open free end thereof, said heated wire slitter including a portion extending transversely and outwardly from said one side of said tubular form to engage and slit a tubular panty hose blank as the blank is drawn onto said tubular form and beyond said heated wire slitter.
Claim 2
Independent Claim
124 words
An apparatus for everting, inspecting and slitting tubular panty hose blanks, said apparatus comprising a. an elongate tubular form having an open free end, b. means associated with the other end of said tubular form for drawing air inwardly through the open free end and along the length of said tubular form to create suction currents therein, and c. a heated wire slitter supported on one side of said tubular form and a predetermined distance from the open free end thereof, said heated wire slitter including a portion extending transversely and outwardly from said one side of said tubular form to engage and slit a tubular panty hose blank as the blank is drawn onto said tubular form and beyond said heated wire slitter.
Claim 3
Dependent Claim
93 words
An apparatus according to claim 1 wherein said heated wire slitter comprises a pair of guide plates extending longitudinally of said elongate tubular form and including portions tapering outwardly and away from the open end of said tubular form, a spacer block connecting said guide plates together in spaced apart relationship, and wherein said heated wire slitter extends outwardly beyond the outwardly tapering portions of said guide plates to engage and slit a hosiery blank as it is drawn upwardly on said form and along the outwardly tapering portions of said guide plates.
Claim 4
Dependent Claim
