Abstract
Abstract An apparatus for automatically packaging folded hosiery into a pouch having a pouch closing flap in which a first means automatically forms the pouch and flap of a single sheet of plastic film with one face of a double-faced adhesive tape adhesively attached to the pouch, in which a second means automatically inserts the folded hosiery into the pouch while adhesively attaching the other face of the double-faced adhesive tape already on the pouch to the flap to close the pouch with the hosiery therein and in which a suction transfer arm automatically transfers the pouch and flap as made by the first means to the second means to insert the hosiery into the pouch.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
150 words
Apparatus for packaging folded hosiery in a pouch, said apparatus comprising pouch forming means to automatically form pouches and pouch closing flaps of a lengthwise extending sheet of plastic film of indefinite length doubled back on itself along a lengthwise extending off center fold line to provide a pair of doubled film layers of the film extending from the fold line and to provide a single layer flap of the film in lateral extension of one of the doubled film layers, means for applying one face of a double-faced adhesive tape to the other of the doubled film layers, means for automatically inserting folded hosiery into the so formed pouches with the double-faced adhesive tape applied to said other of the doubled film layers, and means for thereafter closing the pouches with the flaps so that the flaps are adhesively attached to the other face of the double-faced adhesive tape.
Claim 2
Dependent Claim
150 words
Apparatus for packaging folded hosiery in a pouch, said apparatus comprising pouch forming means to automatically form pouches and pouch closing flaps of a lengthwise extending sheet of plastic film of indefinite length doubled back on itself along a lengthwise extending off center fold line to provide a pair of doubled film layers of the film extending from the fold line and to provide a single layer flap of the film in lateral extension of one of the doubled film layers, means for applying one face of a double-faced adhesive tape to the other of the doubled film layers, means for automatically inserting folded hosiery into the so formed pouches with the double-faced adhesive tape applied to said other of the doubled film layers, and means for thereafter closing the pouches with the flaps so that the flaps are adhesively attached to the other face of the double-faced adhesive tape.
Claim 3
Dependent Claim
50 words
Apparatus as in claim 1 wherein a rotor draws off the double-faced adhesive tape from a roll thereof onto itself, wherein a cutter forms sections of the double-faced adhesive tape, and wherein the rotor transfers the double-faced adhesive tape sections from itself to the other of the doubled film layers.
Claim 4
Dependent Claim
44 words
Apparatus as in claim 2 wherein a heat sealing member seals the doubled film layers together along transversely extending spaced lines thereby to form connected pouches of the film, and wherein the pouches so sealed have a pocket therein between the doubled film layers.
Claim 5
Dependent Claim
39 words
Apparatus as in claim 3 wherein a film cutting unit severs the connected pouches along the spaced lines thereof and severs the single layer of film along corresponding lines thereby to form individual pouches and attached pouch closing flaps.
Claim 6
Dependent Claim
34 words
Apparatus as in claim 1 including an endless series of suction boxes to which the pouches and the flaps are yieldingly retained by suction while the folded hosiery is being inserted into the pouches.
Claim 7
Dependent Claim
29 words
Apparatus as in claim 5 wherein a fixed guide member is provided for a movable guide member and wherein the flaps are temporarily disposed beneath the fixed guide member.
Claim 8
Dependent Claim
22 words
Apparatus as in claim 6 wherein an opener engages one layer of the pouch to open the mouth of the opening therein.
Claim 9
Dependent Claim
32 words
Apparatus as in claim 7 wherein the movable guide member is guided by the fixed guide member to enter into the mouth of the pouch to maintain the same in opened condition.
Claim 10
Dependent Claim
30 words
Apparatus as in claim 8 wherein a hosiery inserting plate with the hosiery thereon is guided by and moves with the movable guide to insert the hosiery into the pouch.
Claim 11
Dependent Claim
26 words
Apparatus as in claim 9 wherein a retaining member temporarily retains the hosiery in the pouch while the inserting plate is being withdrawn from the pouch.
Claim 12
Dependent Claim
39 words
Apparatus as in claim 10 wherein the flap is moved from beneath the fixed guide toward the pouch to cause the flap to be adhesively attached to the other face of the double-faced adhesive tape then on the pouch.
Claim 13
Dependent Claim
25 words
Apparatus as in claim 11 wherein the suction is released from the suction box thereby to permit removal by gravity of the packaged hosiery therefrom.
Claim 14
Dependent Claim
59 words
Apparatus as in claim 12 including a transfer arm to which the pouch and flap is yieldingly attached to said transfer arm by suction, wherein said transfer arm transfers the pouch and flap to said suction boxes to which it is yieldingly attached by suction in the boxes, and wherein the suction in said transfer arm is then released.
