Description
~93~7 PATCII POCKET AND FLAP coNslrRucTIoNs TECHNICAL FIELD
The present invention relates generally to a method of constructing pockets for garments. ~ore particularly, this invention concerns a method of constructing patch pockets and flaps by utilizing adhesives.
93~
B~CKGROU_~D ~R~r In the manufacture o garments, pockets are provided chiefly for carrying useful items. Such useful items can include, for example, keys, money, wallet, handkerchief and so forth. The poc~ets are integratcd into the garment and take the general form of a pouch open at one end for convenient access to the contents.
There are two basic types of pockets: the standard pocket and the patch pocket. The standard pocket is located on the inside of the garment, which includes a pocket slot for access thereto. A standard pocket thus occupies a concealed and protected location in the garment.
In contrast to the standard pocket, a patch pocket is located on the outside of the garment. In its simplest form, a patch pocket comprises a layer or patch of material sewn only at the bottom and side edges to the garment so that articles can be received therebetween.
Patch pockets are most popular in less formal garments such as shirts, trousers, jeans and the like. Patch pockets are also very popular with jackets, sport coats and so on. In many cases, a flap is provided on the garment to cover the open end of the patch pocket. While the standard pocket is relatively more complex and time-consuming, the construction of patch pocl;ets and flaps alsoinvolves numerous manual operations including m~terial cutting, positioning, sewing and trimming. ~or example, the material turnunder in a patch pocket causes unsightly puckering which must be remedied. Such manual operations are time-consuming and tend to increase the cost of garment production.
34~7 As an alternative to traditional tailoring and sewing procedures, there have been some effotts directed to the use of adhesives in garment construction. For example, in copending Canadian patent application serial number 351,743, filed on May 12, 198~ and assigned to the as-signee hereof, there are shown inventions concerning the construction of standard pockets with the aid of adhesives.
Heretofore, however, adhesives have not been employed in the construction of patch pockets or flaps. There is thus a need for patch pocket and flap constructions which utilize adhesive connection techniques to reduce garment production costs.
DISCLOSURE OF INVENTION
According to one aspect of the invention there is pcovided a method of constructing a patch pocket on a garment including the steps of: providing a layer of pocket material characterized by side edges spaced apart a predetermined distance and a bottom edge interconnecting the side edges, the side edges and the bottom edge of the layer of pocket material having a predetermined shape;
providing a layer of liner material characterized by side ~0 edges spaced apart substantially the same distance as the side edges of the layer of pocket material and a bottom edge interconnecting the side edges, the side edges and - the bottom edge of the layer of liner material having s~ubstantially the same shape as that of the layer of pocket material; adhesively joining the layer of liner material to the inside surface of the layer of pocket material with the side and bottom edges of the layer of liner material extending substantially coextensively with the side and bottom edges of the layer of pocket material;
the joined layers of pocket material and liner material forming a patch pocket blank having an obverse side comprising the outside surface of the layer of pocket material and a reverse side comprising the layer of liner material; securing a layer of fusible adhesive to the obverse side of the patch pocket blank adjacent to the side and bottom edges of the layer of pocket material;
folding the side and bottom edges of the patch pocket blank having the fusible adhesive thereon inwardly so that the fusible adhesive faces in the direction of the reverse side of the patch pocket blank; positioning the folded patch pocket blank on the outside surface of the garment with the fusible adhesive engaging the outside surface of the garment and with the reverse side of the patch pocket blank positioned adjacent to the garment; and activating the fusible adhesive to secure the patch pocket blank to the outside surface of the garment.
~1~Y33'~'~
- 4a -Other aspects of the invention are claimed in Canadian patent application 328,662 filed on May 30, 1979, of which the present application is a division.
In accordance with more specific forms of the invention, a method of constructing patch pockets begins with the provision of a patch pocket blank. Fusible adhesive material is then desposited adjacent to the bottom and side edges of the obverse side of the patch pocket blank. The adhesive can be deposited in strip form or in the form of fusible thread in a covering stitch.
According to the preferred construction, the bottom and side edges of the patch pocket blank are then folded inwardly to orient the adhesive in the reverse direction.
Alternatively, the adhesive can be provided on the reverse side of the patch pocket blank to eliminate the t34 7 ,`
step of lolding the ed~es ~hich is rcquired when the adhesive is providecl on the obverse side.
The blank is then positionecl reverse side again.st a garment wherein a patch pocket is desired. After positioning, the patch poc~;et blank is adhesively secured to the yarment by activating the fusible adhesive material. Preferably, activation of the fusible adhesive material is effected by engaging the pocket blank with a heated press, ultrasonic means, or a radiant source capable of converting the adhesive fro~ solid to plastic condition. If desired, a reinforcing stitch can be provided along the adhesively secured edges of the patch pocket.
If desired, a flap can be attached to the garment using similar techniques. Fusible adhesive material is deposited adjacent to the top edge of a flap blank.
The adhesive can be attached to either side of the flap blank. Preferably, the adhesive is deposited on the obverse side, after which the top edge of the flap bank is folded inwardly to orient the adhesive in the reverse direction. The flap blank is then positioned reverse side against the garment, and the fusible adhesive material is activated to adhesively secure the flap in place. If desired, a reinforcing stitch through the top edge of the flap can be added.

_ ~_ _ _ ]~e~errinCJ llOW to the I~L-a~ings, wl~erein li~e rcferellce nunlerals designate like or correspondillg parts tllrougl)out the several views, thcre is illustrated a method of constructin~ pa~ch poc~ets and flaps incorporating the invention. The patch pocket and flap constructions utilize fusible adhesive materials to eliminate several time-consuminy and costly manual procedures which have been re~uired heretofore. The method of the invention can be advantageously employed in the manufacture of shirts, trousers, jackets, or any other g~rment with patch pockets and/o~ flaps. The method reduces garment manufacturing costs and results in strong patch pocket and flap constructions of good looking appearance.
Referring to FIGURES 1 and 2, there is shown a patch pocket blank 10 which is used in the practice of the invention. Patch pocket blank 10 is shown in FIGURE 1 with the obverse side up, the other or reverse side being up in FIGUR~ 2. Patch pocket blank 10 is forrned from a suitable piece of pocket material 12 of sufficient size to permit construction of the desired patch poc~et.
rry~ically, pocket material 12 comprises self goods matching the fabric of the garment. ~laterial 12 can comprise any natural or synthetic cloth material suitable for use in the construction of a patch pocket. It will be understood that the exact composition of pocket material 12 is not critical to the practice of the invention.
For purposes of illustration, patch pocket blank 10 colnprises a generally rectangular section of material 12 havinc3 rounded bottom corners. Tllis is a popular shape for patch pockets. It will be understood that this g particular shape is shown only for purposes of illustra-tion, and that the method of the invention applies equally well to patch pockets of other peripheral shapes, such as those having square corners.
As is best shown in FIGURES 2 and 2a, patch pocket blank 10 is illustrated with material 12 folded down at the top with a conventional liner 14 attached to the reverse side of the material. Preferably, the top edge of liner 14 is also folded down and secured to material 12. The folded top edges of mate-rial 12 and liner 14 are typically fastened together with a stitch 13. Adhesive could be utilizéd in place of stitch 13.
It has been found that a liner material of the fusible type works well as liner 14. For example, material dot coated with adhe~sive on one side is easily attached to pocket material 12 in noncontinuous fashion. Patch pocket blank 10 is thus depicted ~ith a typical rolled top edge and liner. It will be understood, however, that the method of the invention works equally well whether or not pocket blank 10 includes a rolled top edge or a liner 14. The particular construction of the patch pocket blank 10 is not critical to practice of the invention.
The material 12 is then provided with adhesive 16 adja-cent to the bottom and side edges. Adhesive 16 is preferably located continuously about the lower periphery of pocket blank 10. Adhesive 16 can be provided on either the obverse or reverse side of material 12. FIGURE 1 illustrates adhesive 16 positioned on the obverse side of pocket blank 10, which is in accordance with the preferred practice of the invention. If desired, adhesive 16 can be provided along the bottom and side edges of both sides of pocket blank 10. As shown in FIGURE 1, adhesive 16 comprises a strip or ribbon of fusible material having a predetermined width. Adhesive 16 preferably comprises a fusible material, such as polyamide, nylon or polyester materials o~ the type manufactured by General Fabric Fusing Company of Cincinnati, Ohio. If desired, adhesive 16 can be extruded directly onto pocket material 12.
3~7 1() l~e~crring ~o rIGUI~IS ~ and 5, thcre is illus~rated an altcrnate tecllni(~ue for providin~ patcll poc~;et blan~;
10 with adtlesive 16. If desired, adhesive 16 can be applied witll a covering or overedyincJ stitch. A sergc stitch is one such stitch. A serge stitch is ty~ically provided around the edges of a piece of fabric to prevent raying. In a two-thread serge stitch, one or both of the threads can be formecl o a fusible adhesive material, such as polyester, so that the adhesive is simultaneously attached during serging.
~`IGURE 4 illustrates adhesive 16 attached only to the o~verse side of poc~et blank 10 by means of one fusible thread of a serge stitch, with the other non-fusible thread of the serge stitch being located on the reverse side shown in FIGU~E 5. It will be understood that adhesive 16 can be applied along the edges of both sides of patch pocket blan~ 10 with a serge stitch having both threads formed of fusible adhesive material.
Referring now to FIGURES 3, 6 and 7, there is shown a modification of patch pocket blank 10. If desired, pocket blank 10 can be formed from a piece of material 18. The reverse side of material 18 faces up in FIGURES 3, 6 and 7. Adhesive 20 is next provided along the top edge of material 1~ on the reverse side thereof.
Adhesive 20 can be attached in the form of a strip of fusible adhesive material, as shown in YIGURE 3, or in the form of adhesive thread in a serge stitch, as shown in FIGU~E 6. Adhesive 2U comprises a fusible adhesive material similar to that utilized for adhesive 16. The top edge of material 18 is then folded down as shown in FIGURE 7 to position adhesive 20 bet~een adjacent layers of material 18. As will be described more fully hereina~ter, adhcsive 20 is tl-en activated to adhesively secure the rolled top edge of material 18. Preferably, the top corners of material 18 are notched as shown to allow for.~adllesive 16 when the top edge o material 1 is folded down.
93~'7 ~ eerring to FIG~I~E~ ~ and ~, tl~e bottom and side edc~es o~ patch yocket blank 10 are next folded inwardly in the preferrcd embodiment of the invention. l`he reverse side of pocket blank 10 faccs up in ~I~U~E ~. If adhesive S 16 is positioned on the obverse side of pocket blank 10, the bottom and side edges are thus folded inwardly to orient the aahesive in the reverse direction. The use of adhesive 16 adjacent to the bottom and side e~c~es minimizes the amount of turn~nder required, resultin~ in less iO puckering and material waste. It will be understood that if adhesive 16 is applied to the reverse side of pocket blank lO, then the inward folding of tlle bottom and side edges lS unnecessary.
Refe~^ring to FIGURES 10 and 11, patch pocket blank lS 10 is next positioned on the outside of a garment 22 wherein a patch pocket is desired. For example, garment 22 can comprise a shirt, trousers, jacket or the like.
Garment 22 can be formed of any natural or synthetic cloth material, the exact composition of which is not critical to the practice of the invention. The reverse side of patch pocket blank 10 is positioned against the outside surface of garment 22 with adhesive 16 therebetween. In the preferred embodilnellt of the invention, the bottom and side edges of patch pocket blank 10 are folded inwardly to properly orient adhesive 16. Of course, if adhesive 16 is provided along the edges of both sides of pocket blank 10, then adhesive will be positioned between adjacent layers of the pocket blank as well as between garment 22 and tl-e pocket blank.
After positioning, the patch pocket blank 10 is adhesively secured in place. Fusible adhesive 16 is activated to convert it from a solid to a plastic condition. ~ctivation of adt-esive 16, as well as adhesive 20 if desired, is preferably accomplished by engagin(3 the obverse side of pocket blank 10 with a heated press, ultrasonic or microwave means, or a 3~7 ~;
-. 1~
radiarlt source. rile tempel-ature ancl duration of en~agement are su~ficient to melt the ac~hesive so that adjacel)t portions of patch poe~;et blallk l0 and (~arment 22 become perrneated to form a bonded conl)ection. It will be appreciatecl that the use of a heated press to activate adhesive 16 simultaneously presses the periphery of the patell pocket. After activation, it will be understoocl that the patch pocket is secured witll an adllesive eonnection which is stron~ and durable as well as resistant to ~3arment eleaning processes. Preferably, a stiteh 24 is sewn along ~he lower periphery of the pateh poeket to reinforee the eonneetion between poeket blank 10 and garment 22, and to lend a finished appearanee to the patch pocket.
Referring now to FIGURES 12, 12a and 13, there is shown a flap blank 30 whieh ean be used in adding a flap to the pateh poeket hereinabove deseribed, if desired. Flap blank 30 ean be formed of a single pieee of flap material 32 eomprising any natural or synthetie eloth material suitable for sueh use. Typieally, however, the flap blank 30 eomprises two pieees of material 32 and 33. The bottom edges of material 32 and 33 are folded in~ard and fastened together with a stiteh 34 as is best shown in FIGURE 12a. Adhesive ean be used in plaee of stiteh 3~1, if desired. The exaet eomposition of pieces of flap material 32 and 33 is not eritical to the practice of the invention.
It will be understood that the particular eonstruetion of flap blank 30 is not eritieal to the invention.
The flap construction is carried out usin~3 teehniques similar to the pateh poeket eonstruetion. Adhesive 35 is deposited adjacent to the top ed~e of flap blank 30.
~dhesive 35 comyrises a fusible adhesive material such as polyamide, nylon, polyester or the like. ~clhesive 35 can be applied in the form of a strip of material, as shown in FIGU~E 12, or in the form of a thread of fusible material in a ser~e stiteh, as shown in FIGURE 13. In aeeordance with the preferred embodimellt of the flap 34~
, .
corlsl:ruc~ , a(lhesive 35 is provide~l or- the obvc~rse sidc o~ Lap m~l~crial 32. If desired, adllcsive 35 can be provided along thc top edcJe o botll sides oL flap material 32, or only on tlle reverse side thereo.
~ efcrring to lIGU~E 1~, the top edge of the preferred embodinlent of flap blank 30 is folded downwardly to orient adhesive 35 in the reverse direction. The reverse side of flap blank 30 faces up in FIGUI~ . If adhesive 35 is provided only on the reverse side of material 32, it will be apparent that down~ard folding of the top edge of pocket blank 30 is unnecessary.
Referring to FIGUR~S 15 and 16, flap blank 30 is next positioned on garment 22 wherein a flap is desired. The reverse side of flap blank 30 is positioned against the outside surface of garment 22 with adhesive 35 there-between. For purposes of illustration, flap blank 30 is shown in conjunction with a patch poc~et 36 constructed according to the invention. Flap blank 30 is thus located on garment 22 so as to cover the top end of patch poc~et 36. However, it will be appreciated that flap blank 30 is a separate component which can be added to garment 22 with or without an accompanying patch poc~et.
After location, the flap blank 30 is adhesively secured in place. Adhesive 35 is activated with a heated press, ultrasonic or microwave means, or a radiant source to securely bond flap blank 30 to garment 22. The use of a heated press is desirable because it presses the folded top edge of pocket blank 30 during activation of adhesive 35. Preferably, a stitch 38 is sewn along the upper edge of the flap to give it an attractive appearance and to reinforce the connection between flap blank 30 and ~arment 22.
In view of the foregoing description, it will be understood tl)at the present invention comprises a method of constructing patch pockets and flaps which incorporates nurnerous advantacJes over the prior art. One important advantage ~nvolves-tlle use of fusible adhesive materials ~ 93~7 in placc ol tr~n(li~iollcll sc~/in(J o~Jcratiol)s. sewn patch ~ockets have hcrctc)foLc re~uired mc)re material turn2d uncler along ~hc cclgcs, re-iultiny in unsi(Jhtly puc~ering and aclditiollal Inclnual steps to correct the puckering.
~lso there is greater material waste whcn more turnunder is requirecl. ~rhe usc of fusiblè adhesives minimizes both material turnunder and puckering therefrom, and eliminates several marlual operations which were heretofore required in the construction of patch pockets and flaps.
Other advantayes from the use of the invention will readily sugc~est themselves to those s};illed in the art.
~ lthou~h particular embodiments of the invention have ~een illustrated in the accompanyiny Drawings and described in the foregoing Detailed Description, it will be understood that the present application is not limited to the embodiments disclosed but is intended to embrace any alternatives, modifications, rearrangements and substitutions of parts and/or elements as fall within the spirit and scope of the invention.
The present invention relates generally to a method of constructing pockets for garments. ~ore particularly, this invention concerns a method of constructing patch pockets and flaps by utilizing adhesives.

For purposes of illustration, patch pocket blank 10 colnprises a generally rectangular section of material 12 havinc3 rounded bottom corners. Tllis is a popular shape for patch pockets. It will be understood that this g particular shape is shown only for purposes of illustra-tion, and that the method of the invention applies equally well to patch pockets of other peripheral shapes, such as those having square corners.
As is best shown in FIGURES 2 and 2a, patch pocket blank 10 is illustrated with material 12 folded down at the top with a conventional liner 14 attached to the reverse side of the material. Preferably, the top edge of liner 14 is also folded down and secured to material 12. The folded top edges of mate-rial 12 and liner 14 are typically fastened together with a stitch 13. Adhesive could be utilizéd in place of stitch 13.
It has been found that a liner material of the fusible type works well as liner 14. For example, material dot coated with adhe~sive on one side is easily attached to pocket material 12 in noncontinuous fashion. Patch pocket blank 10 is thus depicted ~ith a typical rolled top edge and liner. It will be understood, however, that the method of the invention works equally well whether or not pocket blank 10 includes a rolled top edge or a liner 14. The particular construction of the patch pocket blank 10 is not critical to practice of the invention.
The material 12 is then provided with adhesive 16 adja-cent to the bottom and side edges. Adhesive 16 is preferably located continuously about the lower periphery of pocket blank 10. Adhesive 16 can be provided on either the obverse or reverse side of material 12. FIGURE 1 illustrates adhesive 16 positioned on the obverse side of pocket blank 10, which is in accordance with the preferred practice of the invention. If desired, adhesive 16 can be provided along the bottom and side edges of both sides of pocket blank 10. As shown in FIGURE 1, adhesive 16 comprises a strip or ribbon of fusible material having a predetermined width. Adhesive 16 preferably comprises a fusible material, such as polyamide, nylon or polyester materials o~ the type manufactured by General Fabric Fusing Company of Cincinnati, Ohio. If desired, adhesive 16 can be extruded directly onto pocket material 12.

10 with adtlesive 16. If desired, adhesive 16 can be applied witll a covering or overedyincJ stitch. A sergc stitch is one such stitch. A serge stitch is ty~ically provided around the edges of a piece of fabric to prevent raying. In a two-thread serge stitch, one or both of the threads can be formecl o a fusible adhesive material, such as polyester, so that the adhesive is simultaneously attached during serging.
~`IGURE 4 illustrates adhesive 16 attached only to the o~verse side of poc~et blank 10 by means of one fusible thread of a serge stitch, with the other non-fusible thread of the serge stitch being located on the reverse side shown in FIGU~E 5. It will be understood that adhesive 16 can be applied along the edges of both sides of patch pocket blan~ 10 with a serge stitch having both threads formed of fusible adhesive material.
Referring now to FIGURES 3, 6 and 7, there is shown a modification of patch pocket blank 10. If desired, pocket blank 10 can be formed from a piece of material 18. The reverse side of material 18 faces up in FIGURES 3, 6 and 7. Adhesive 20 is next provided along the top edge of material 1~ on the reverse side thereof.
Adhesive 20 can be attached in the form of a strip of fusible adhesive material, as shown in YIGURE 3, or in the form of adhesive thread in a serge stitch, as shown in FIGU~E 6. Adhesive 2U comprises a fusible adhesive material similar to that utilized for adhesive 16. The top edge of material 18 is then folded down as shown in FIGURE 7 to position adhesive 20 bet~een adjacent layers of material 18. As will be described more fully hereina~ter, adhcsive 20 is tl-en activated to adhesively secure the rolled top edge of material 18. Preferably, the top corners of material 18 are notched as shown to allow for.~adllesive 16 when the top edge o material 1 is folded down.
93~'7 ~ eerring to FIG~I~E~ ~ and ~, tl~e bottom and side edc~es o~ patch yocket blank 10 are next folded inwardly in the preferrcd embodiment of the invention. l`he reverse side of pocket blank 10 faccs up in ~I~U~E ~. If adhesive S 16 is positioned on the obverse side of pocket blank 10, the bottom and side edges are thus folded inwardly to orient the aahesive in the reverse direction. The use of adhesive 16 adjacent to the bottom and side e~c~es minimizes the amount of turn~nder required, resultin~ in less iO puckering and material waste. It will be understood that if adhesive 16 is applied to the reverse side of pocket blank lO, then the inward folding of tlle bottom and side edges lS unnecessary.
Refe~^ring to FIGURES 10 and 11, patch pocket blank lS 10 is next positioned on the outside of a garment 22 wherein a patch pocket is desired. For example, garment 22 can comprise a shirt, trousers, jacket or the like.
Garment 22 can be formed of any natural or synthetic cloth material, the exact composition of which is not critical to the practice of the invention. The reverse side of patch pocket blank 10 is positioned against the outside surface of garment 22 with adhesive 16 therebetween. In the preferred embodilnellt of the invention, the bottom and side edges of patch pocket blank 10 are folded inwardly to properly orient adhesive 16. Of course, if adhesive 16 is provided along the edges of both sides of pocket blank 10, then adhesive will be positioned between adjacent layers of the pocket blank as well as between garment 22 and tl-e pocket blank.
After positioning, the patch pocket blank 10 is adhesively secured in place. Fusible adhesive 16 is activated to convert it from a solid to a plastic condition. ~ctivation of adt-esive 16, as well as adhesive 20 if desired, is preferably accomplished by engagin(3 the obverse side of pocket blank 10 with a heated press, ultrasonic or microwave means, or a 3~7 ~;
-. 1~
radiarlt source. rile tempel-ature ancl duration of en~agement are su~ficient to melt the ac~hesive so that adjacel)t portions of patch poe~;et blallk l0 and (~arment 22 become perrneated to form a bonded conl)ection. It will be appreciatecl that the use of a heated press to activate adhesive 16 simultaneously presses the periphery of the patell pocket. After activation, it will be understoocl that the patch pocket is secured witll an adllesive eonnection which is stron~ and durable as well as resistant to ~3arment eleaning processes. Preferably, a stiteh 24 is sewn along ~he lower periphery of the pateh poeket to reinforee the eonneetion between poeket blank 10 and garment 22, and to lend a finished appearanee to the patch pocket.
Referring now to FIGURES 12, 12a and 13, there is shown a flap blank 30 whieh ean be used in adding a flap to the pateh poeket hereinabove deseribed, if desired. Flap blank 30 ean be formed of a single pieee of flap material 32 eomprising any natural or synthetie eloth material suitable for sueh use. Typieally, however, the flap blank 30 eomprises two pieees of material 32 and 33. The bottom edges of material 32 and 33 are folded in~ard and fastened together with a stiteh 34 as is best shown in FIGURE 12a. Adhesive ean be used in plaee of stiteh 3~1, if desired. The exaet eomposition of pieces of flap material 32 and 33 is not eritical to the practice of the invention.
It will be understood that the particular eonstruetion of flap blank 30 is not eritieal to the invention.
The flap construction is carried out usin~3 teehniques similar to the pateh poeket eonstruetion. Adhesive 35 is deposited adjacent to the top ed~e of flap blank 30.
~dhesive 35 comyrises a fusible adhesive material such as polyamide, nylon, polyester or the like. ~clhesive 35 can be applied in the form of a strip of material, as shown in FIGU~E 12, or in the form of a thread of fusible material in a ser~e stiteh, as shown in FIGURE 13. In aeeordance with the preferred embodimellt of the flap 34~
, .
corlsl:ruc~ , a(lhesive 35 is provide~l or- the obvc~rse sidc o~ Lap m~l~crial 32. If desired, adllcsive 35 can be provided along thc top edcJe o botll sides oL flap material 32, or only on tlle reverse side thereo.
~ efcrring to lIGU~E 1~, the top edge of the preferred embodinlent of flap blank 30 is folded downwardly to orient adhesive 35 in the reverse direction. The reverse side of flap blank 30 faces up in FIGUI~ . If adhesive 35 is provided only on the reverse side of material 32, it will be apparent that down~ard folding of the top edge of pocket blank 30 is unnecessary.
Referring to FIGUR~S 15 and 16, flap blank 30 is next positioned on garment 22 wherein a flap is desired. The reverse side of flap blank 30 is positioned against the outside surface of garment 22 with adhesive 35 there-between. For purposes of illustration, flap blank 30 is shown in conjunction with a patch poc~et 36 constructed according to the invention. Flap blank 30 is thus located on garment 22 so as to cover the top end of patch poc~et 36. However, it will be appreciated that flap blank 30 is a separate component which can be added to garment 22 with or without an accompanying patch poc~et.
After location, the flap blank 30 is adhesively secured in place. Adhesive 35 is activated with a heated press, ultrasonic or microwave means, or a radiant source to securely bond flap blank 30 to garment 22. The use of a heated press is desirable because it presses the folded top edge of pocket blank 30 during activation of adhesive 35. Preferably, a stitch 38 is sewn along the upper edge of the flap to give it an attractive appearance and to reinforce the connection between flap blank 30 and ~arment 22.
In view of the foregoing description, it will be understood tl)at the present invention comprises a method of constructing patch pockets and flaps which incorporates nurnerous advantacJes over the prior art. One important advantage ~nvolves-tlle use of fusible adhesive materials ~ 93~7 in placc ol tr~n(li~iollcll sc~/in(J o~Jcratiol)s. sewn patch ~ockets have hcrctc)foLc re~uired mc)re material turn2d uncler along ~hc cclgcs, re-iultiny in unsi(Jhtly puc~ering and aclditiollal Inclnual steps to correct the puckering.
~lso there is greater material waste whcn more turnunder is requirecl. ~rhe usc of fusiblè adhesives minimizes both material turnunder and puckering therefrom, and eliminates several marlual operations which were heretofore required in the construction of patch pockets and flaps.
