Description

【0001】
【産業上の利用分野】
この発明は、各種パーツのプレス機に係り、特に、生地に対し接着剤(多数の接着粒体や接着フィルムシート)を介して芯地を重ねたパーツを加熱してこの接着剤を溶融した後に加圧して接着する衣料用連続芯地接着機に関するものである。
【0002】
【従来の技術】
特開平6−286900号公報に示す従来の衣料用連続芯地接着機においては、パーツ搬入口側からパーツ搬出口側に渡り上下両平ベルト間でパーツを挟持して搬送し得るようにこの上下両平ベルトが互いに近接されて配設され、このパーツ搬入口側とパーツ搬出口側との間には上下両平ベルトを介してパーツを加熱するヒータが設けられ、前記パーツ搬出口側には上下両平ベルト間で挟持されたパーツを上下両平ベルトを介して最終加圧する上下両回転プレスローラが設けられている。
【0003】
特に、図4に示すように、前記パーツ搬出口4側には上下両回転プレスローラ6,8間のメイン加圧部Mよりもパーツ搬送方向Dの上流側で、回転押圧ローラ36が下側回転プレスローラ8に隣接して上下の無端状平ベルト11,12に対しその下方から圧接されている。この回転押圧ローラ36により、上下両平ベルト11,12間で挟持されたパーツを上下両平ベルト11,12を介して予備加圧する。
【0004】
【発明が解決しようとする課題】
ところが、上下両回転プレスローラ6,8間のメイン加圧部Mと回転押圧ローラ36との間では、上下両平ベルト11,12を支えるものがなく、上下両平ベルト11,12が上下方向へ自由に撓み、それらの間では上下両平ベルト11,12が不安定な状態となる。しかも、加圧前では、前記接着剤が溶融前であるため、生地と芯地とはまだ互いにずれ易い状態にある。従って、上下両平ベルト11,12間に挟持されたパーツにしわが生じ易くなる。
【0005】
また、ある程度柔軟な上下両平ベルト11,12が上下両回転プレスローラ6,8間のメイン加圧部Mに挟入されると、その加圧力により上下両平ベルト11,12の肉厚が通常の肉厚よりも少し薄くなり、その肉厚変化によりメイン加圧部Mの直前で上下両平ベルト11,12が上下へ僅かに膨らむ。ところが、上下両平ベルト11,12にこのような膨出部が生じると、その膨出部が搬送抵抗となり、メイン加圧部Mと回転押圧ローラ36との間で上下両平ベルト11,12が上下方向へ波打つように撓み易くなる。従って、波形状の上下両平ベルト11,12間に挟持されたパーツにしわが生じ易くなり、商品価値の低下を来す。
【0006】
本発明は前記両回転プレスローラと回転押圧ローラと両ベルトとの間の位置関係を改良してパーツにしわが発生するのを極力防止することを目的としている。
【0007】
【課題を解決するための手段】
後記実施例の図面(図1〜3)の符号を援用して本発明を説明する。
第一発明にかかるプレス機の加圧装置は下記のように構成されている。
【0008】
パーツ搬入口(3)側からパーツ搬出口(4)側に渡り両ベルト(11,12)が互いに近接されて挟持走行部(13,14)が延設されている。この両ベルト(11,12)の挟持走行部(13,14)間で挟持されたパーツ(P)をこの両挟持走行部(13,14)を介して加圧する両プレスローラ(6,8)が設けられている。
【0009】
前記パーツ搬出口(4)側には両プレスローラ(6,8)間のメイン加圧部(M)よりもパーツ搬送方向(D)の上流側で、この両プレスローラ(6,8)のうち一方の第一プレスローラ(6)に対し前記両挟持走行部(13,14)を挟入するとともに押圧してサブ加圧部(S)とする押圧ローラ(36)が設けられている。
【0010】
このメイン加圧部(M)とサブ加圧部(S)との間で両挟持走行部(13,14)を第一プレスローラ(6)に沿わせて接触させるとともに、前記第一プレスローラ(6)の軸心(5a)と押圧ローラ(36)の軸心(35a)とを結ぶ法線上にあるサブ加圧部(S)において、第一プレスローラ(6)と押圧ローラ(36)との間に働く加圧力(F)の方向を、第一プレスローラ(6)の軸心(5a)よりもパーツ搬送方向(D)の上流側の偏心位置を通るようにして、第一プレスローラ(6)の軸心(5a)と押圧ローラ(36)の軸心(35a)とを結ぶ法線に沿って働く法線分力(Fn)と該法線分力(Fn)に対し直交する接線方向の分力(Ft)とを働かせている。
【0013】
発明にかかるプレス機の加圧装置は前記第一発明に下記の構成を加えている。パーツ搬入口(3)とパーツ搬出口(4)との間には両挟持走行部(13,14)間のパーツ(P)を加熱する加熱手段(27,28)が設けられている。
【0014】
【作用】
第一発明では、両加圧部(M,S)間で両ベルト(11,12)の挟持走行部(13,14)が第一プレスローラ(6)に沿って接触しながら移動する。従って、この両挟持走行部(13,14)間に挟まれたパーツ(P)も、両加圧部(M,S)で第一プレスローラ(6)に沿って安定した状態で、メイン加圧部(M)により加圧されて搬出される。
【0015】
また、加圧力(F)がサブ加圧部(S)に働くと、法線分力(Fn)は両ベルト(11,12)の挟持走行部(13,14)及びそれらの間のパーツ(P)を押圧ローラ(36)により第一プレスローラ(6)に対し圧接する予備加圧力として働き、メイン加圧部(M)で最終加圧される両挟持走行部(13,14)及びパーツ(P)がこの両加圧部(M,S)間で支えられる。一方、接線分力(Ft)は両加圧部(M,S)間で両挟持走行部(13,14)及びパーツ(P)をパーツ搬送方向(D)対し逆向きに引張る力として働く。従って、両挟持走行部(13,14)及びパーツ(P)は、パーツ搬送方向(D)の搬送力とそれに対し逆向きの接線分力(Ft)とにより引張られる。
【0016】
発明では、第一発明の作用のほか、例えばパーツ(P)としての生地と芯地との間に溶融前の接着剤を重ねて加圧前に加熱手段(27,28)によりこの接着剤を溶融する。
【0017】
【実施例】
以下、本発明の一実施例に係るプレス機(連続芯地接着機)を図1から図3を参照して説明する。
【0018】
図3に概略的に示す連続芯地接着機においては、テーブル1上にパーツ搬送ケース2が載設され、同ケース2にはパーツ搬入口3とパーツ搬出口4とが設けられている。図1及び図2に概略的に示すパーツ加圧装置はこのパーツ搬送ケース2内に設けられている。次に、このパーツ加圧装置を詳述する。
【0019】
前記パーツ搬出口4側において、上側駆動軸5上の上側回転プレスローラ6と下側駆動軸7上の下側回転プレスローラ8とが相対向して配設されている。上側駆動軸5とともに回転する上側回転プレスローラ6には回転軸心5aを中心とする円形外周面9が形成されている。下側駆動軸7とともに回転する下側回転プレスローラ8には回転軸線7aを中心とする円形外周面10が形成されている。この上側回転プレスローラ6の円形外周面9には無端状の上側平ベルト11が巻き掛けられている。この下側回転プレスローラ8の円形外周面10には無端状の下側平ベルト12が巻き掛けられている。この上下両平ベルト11,12は上下両回転プレスローラ6,8間で加圧されている。
【0020】
このパーツ搬出口4側のメイン加圧部Mから前記パーツ搬入口3側に渡り、上側平ベルト11の挟持走行部13と下側平ベルト12の挟持走行部14とが互いに近接されて延設されている。
【0021】
この上下両挟持走行部13,14の延設方向がパーツ搬送方向Dになっている。下側駆動軸7の回転軸線7aが上側駆動軸5の回転軸心5aよりもパーツ搬送方向Dの下流側に位置し、下側回転プレスローラ8の円形外周面10が上側回転プレスローラ6の円形外周面9よりもパーツ搬送方向Dの下流側へ突出して上下両円形外周面9,10間が段差状になっている。前記メイン加圧部Mはこの両回転軸心5a,7aを結ぶ法線上にある。上下両回転プレスローラ6,8よりもパーツ搬送方向Dの下流側で上下両回転剥離ローラ15,16がそれらの円形外周面9,10上の上下両平ベルト11,12に接触している。
【0022】
前記上側平ベルト11は上側回転プレスローラ6から支持ローラ17と支持ローラ18とテンションローラ19と蛇行修正ローラ20とに掛け渡され、さらに前記パーツ搬入口3側で上側従動ローラ21に掛け渡されて、上側挟持走行部13としてパーツ搬送方向Dに沿う。前記下側平ベルト12は下側回転プレスローラ8から支持ローラ22と支持ローラ23とテンションローラ24と蛇行修正ローラ25とに掛け渡され、さらに前記パーツ搬入口3側で下側従動ローラ26に掛け渡されて、下側挟持走行部14としてパーツ搬送方向Dに沿う。下側従動ローラ26は上側従動ローラ21よりもパーツ搬送方向Dの上流側に位置し、この上下両従動ローラ21,26間で下側挟持走行部14上がパーツ供給載置面14aになっている。
【0023】
前記パーツ搬入口3側の上側従動ローラ21とパーツ搬出口4側の上側回転プレスローラ6との間で上側平ベルト11の挟持走行部13の上に複数の上側ヒータ27(加熱手段)がパーツ搬送方向Dに沿って並設されている。パーツ搬入口3側の下側従動ローラ26とパーツ搬出口4側の下側回転プレスローラ8との間で下側平ベルト12の挟持走行部14の下に複数の下側ヒータ28(加熱手段)がパーツ搬送方向Dに沿って並設され、各上側ヒータ27間に位置している。
【0024】
特に本実施例においては、前記パーツ搬出口4側にあるパーツ加圧手段が改良されている。次に、このパーツ加圧手段を図2を主に参照して詳述する。
前記下側回転プレスローラ8よりもパーツ搬送方向Dの上流側で上側回転プレスローラ6の下方に回動支軸29が上下両駆動軸5,7の回転軸心5a,7aに沿って架設され、この支軸29の軸心29a方向両側に大レバー30が垂立面上で一体回動可能に支持され、この支軸29からパーツ搬送方向Dの上流側へ大レバー30の駆動腕部30aが延設されているとともに、この支軸29からパーツ搬送方向Dの下流側へ大レバー30の従動腕部30bが延設されている。この両レバー30の従動腕部30b間に前記下側駆動軸7が回転可能に支持されている。この両レバー30の駆動腕部30aのうち一方の駆動腕部30aには駆動エアシリンダ31のピストンロット31aがリンク32を介して連結されている。そして、このピストンロット31aが下動すると、リンク32を介して大レバー30が回動し、下側駆動軸7上の下側回転プレスローラ8が上下両平ベルト11,12を介して上側回転プレスローラ6に圧接される。
【0025】
前記下側回転プレスローラ8よりもパーツ搬送方向Dの上流側で上側回転プレスローラ6と回動支軸29との間に回動支軸33がこの回動支軸29に沿って架設され、この回動支軸33の軸心33a方向の両側に小レバー34が垂立面上で一体回動可能に支持されている。この両レバー34の先端部間で上下両駆動軸5,7に沿う従動軸35が回転可能に支持され、この従動軸35上に回転押圧ローラ36が支持されている。この回転押圧ローラ36には従動軸35の軸心35aを中心とする円形外周面37が形成され、この円形外周面37の直径は上下両回転プレスローラ6,8と円形外周面9,10の直径よりも小さくなっている。
【0026】
前記大レバー30付近でそれぞれ押圧シリンダ38が回動可能に取り付けられ、そのピストンロット38aの先端部が従動軸35の軸心35a上で小レバー34に連結されている。このピストンロット38aの伸縮方向Eは前記従動軸35の軸心35aを通る。この回転押圧ローラ36よりもパーツ搬送方向Dの上流側で上側平ベルト11上にガイドローラ39が支持されている。そして、このピストンロット38aが上方へ伸長すると、小レバー34が回動し、このガイドローラ39と上側回転プレスローラ6との間で上下両平ベルト11,12の挟持走行部13,14が上方へ押圧されて回転押圧ローラ36に巻き掛けられる。この押圧状態では、回転押圧ローラ36の円形外周面37が上側回転プレスローラ6の円形外周面9対し上下両平ベルト11,12を介して加圧され、このサブ加圧部Sが上側駆動軸5の回転軸心5aと従動軸35の軸心35aとを結ぶ法線上に位置する。ピストンロット38aの伸縮に関係なくその伸縮方向Eは上側駆動軸5の回転軸心5aよりもパーツ搬送方向Dの上流側である偏心位置を常に通る。
【0027】
次に、このように構成されたパーツ加圧手段を中心にして連続芯地接着機の作用を述べる。
パーツPは生地に芯地を接着剤(多数の接着粒体や接着フィルムシート)を介して重ねたものである。パーツ搬入口3側で下側平ベルト12の挟持走行部14上のパーツ供給載置面14aにこのパーツPを載せると、このパーツPは上下両平ベルト11,12の挟持走行部13,14間に挟持されてパーツ搬送方向Dへ搬送される。パーツPは上下両挟持走行部13,14間で挟持されながら上下両ヒータ27,28間を通り、その搬送中にパーツP内の接着剤が溶融される。
【0028】
その後、パーツPはガイドローラ39の下側を通って回転押圧ローラ36の円形外周面37上に至り、上下両挟持走行部13,14間で挟持されたまま上側回転プレスローラ6の円形外周面9と回転押圧ローラ36の円形外周面37との間のサブ加圧部Sに挟入される。そのサブ加圧部SでパーツPは軽く予備加圧される。
【0029】
さらに、パーツPはサブ加圧部Sから上側回転プレスローラ6の円形外周面9に沿って搬送される。そして、上側回転プレスローラ6の円形外周面9と下側回転プレスローラ8の円形外周面10との間のメイン加圧部Mに対しパーツPが上下両挟持走行部13,14間で挟持されながら挟入される。そのメイン加圧部MでパーツPは最終加圧される。
【0030】
次に、上下両挟持走行部13,14が上下方向へ分かれるため、パーツPが上下両挟持走行部13,14から分離されて搬出される。この場合、上下両回転剥離ローラ15,16は上下両回転プレスローラ6,8へのパーツPの巻込みを防止する。
【0031】
駆動エアシリンダ31のピストンロット31aが伸長すると、大レバー30が回動して下側回転プレスローラ8が上側回転プレスローラ6から離れる。また、押圧エアシリンダ38のピストンロット38aが収縮すると、小レバー34が回動し、回転押圧ローラ36が上側回転プレスローラ6から離れる。従って、各ローラ6,8,36が互いに離間し、メンテナンスを行い易くなる。
【0032】
本実施例は下記(イ)〜(ハ)の特徴を有する。
(イ) 上下両回転プレスローラ6,8間のメイン加圧部Mの他に、上側回転プレスローラ6と回転押圧ローラ36との間にサブ加圧部Sを設けたので、この両加圧部M,S間で上下両平ベルト11,12の挟持走行部13,14が上側回転プレスローラ6の円形外周面9に沿って接触しながら移動する。従って、接着剤が溶融前であるために生地と芯地とがまだ互いにずれ易い加圧前状態にあっても、この上下両挟持走行部13,14間に挟まれたパーツPは、両加圧部M,S間で上側回転プレスローラ6の円形外周面9に沿って安定した状態で、メイン加圧部Mにより加圧されて搬出され、パーツPにしわが生じにくくなる。
【0033】
(ロ) 回転押圧ローラ36の軸心35aを通る押圧シリンダ38のピストンロット38aの伸縮方向Eに対し平行になっているサブ加圧部S上の加圧力Fは、上側回転プレスローラ6の回転軸心5aよりもパーツ搬送方向Dの上流側を通る。そのため、この加圧力Fは、サブ加圧部Sに働いた場合、次の二種類の分力として働く。第一に、上側回転プレスローラ6の回転軸心5aと回転押圧ローラ36の軸心5aとを結ぶ法線に沿って働く法線分力Fである。この法線分力Fは、上下両平ベルト11,12の挟持走行部13,14及びそれらの間のパーツPを回転押圧ローラ36により上側回転プレスローラ6に対し圧接する予備加圧力として働き、メイン加圧部Mで最終加圧される上下両挟持走行部13,14及びパーツPが上側回転プレスローラ6の円形外周面9に沿うようにこの両加圧部M,S間で支えられる。第二に、この法線に対し直交する接線方向の分力Fである。この接線分力Fは両加圧部M,S間で上側回転プレスローラ6の円形外周面9に沿う上下両挟持走行部13,14及びパーツPをパーツ搬送方向Dに対し逆向きに引張る力として働く。従って、上下両挟持走行部13,14及びパーツPは、パーツ搬送方向Dの搬送力とそれに対し逆向きの接線分力Fとにより引張られながら円形外周面9に沿って圧接され、この両方向へパーツPが引き伸ばされてパーツPにしわが生じにくくなる。
【0034】
(ハ) 生地と芯地との間に溶融前の接着フィルムシートを重ねて前記加圧前にヒータ27,28によりこの接着フィルムシートを溶融しているので、生地と芯地との接着が行い易くなる。
【0035】
前記実施例以外に下記(イ)〜(ハ)のように構成してもよい。
(イ) 前記実施例で上下両ヒータ27,28を省略する。この場合には、下側回転プレスローラ8の挟持走行部14のパーツ供給載置面14aに載せるパーツPにおいて、生地と芯地との間に溶融接着剤を塗布する。
【0037】
(ハ) 前述した実施例では、上側回転プレスローラ6の回転軸心5aと下側回転プレスローラ8の回転軸心7aとを結ぶ法線方向へ、下側回転プレスローラ8が上側回転プレスローラ6に対し加圧されている。この下側回転プレスローラ8の加圧方向は、上側回転プレスローラ6の回転軸心5aよりもパーツ搬送方向Dの下流側の偏心位置を通るようにしてもよい。この場合には、メイン加圧部Mで加圧力の接線分力が搬送力に加えてパーツ搬送方向Dに働き、前述した回転押圧ローラ36の場合と同様に両加圧部M,S間でパーツPを上側回転プレスローラ6の円形外周面9に沿って引張る。従って、メイン加圧部Mにおける搬送力及び引張り力とサブ加圧部Sにおける引張り力とにより、パーツPが円形外周面9に沿って引き伸ばされ、パーツPにしわが生じにくくなる。
【0038】
【発明の効果】
第一発明にかかるプレス機のパーツ加圧装置によれば、両プレスローラ(6,8)のメイン加圧部(M)の他に、第一プレスローラ(6)と押圧ローラ(36)との間にサブ加圧部(S)を設けたので、両挟持走行部(13,14)に挟まれたパーツ(P)が安定した状態で搬出され、パーツ(P)にしわが生じにくくなる。
【0039】
また、両挟持走行部(13,14)及びパーツ(P)が接線分力(Ft)により引き伸ばされ、パーツ(P)にしわが生じにくくなる。
【0040】
発明によれば、第一発明の効果に加え、例えばパーツ(P)としての生地と芯地との接着が行い易くなる。

[0001]
[Industrial applications]
The present invention relates to a press machine for various parts, and in particular, after heating a part in which an interlining is overlapped with a cloth via an adhesive (a large number of adhesive granules or adhesive film sheets) to melt the adhesive. The present invention relates to a continuous interlining applicator for clothing that adheres by applying pressure.
[0002]
[Prior art]
In a conventional continuous interlining machine for clothing disclosed in Japanese Patent Application Laid-Open No. 6-286900, the upper and lower belts are sandwiched between upper and lower flat belts from the parts entrance side to the parts exit side so as to be conveyed. The two flat belts are arranged close to each other, and a heater for heating the parts via the upper and lower flat belts is provided between the parts entrance side and the parts exit side, and the parts exit side is Both upper and lower rotary press rollers for final pressing the parts sandwiched between the upper and lower flat belts via the upper and lower flat belts are provided.
[0003]
In particular, as shown in FIG. 4, the rotation pressing roller 36 is located on the part outlet 4 side on the upstream side of the main pressing part M between the upper and lower rotary pressing rollers 6, 8 in the part conveying direction D, and on the lower side. The upper and lower endless flat belts 11 and 12 are pressed adjacent to the rotary press roller 8 from below. The parts sandwiched between the upper and lower flat belts 11 and 12 are pre-pressed by the rotary pressing roller 36 via the upper and lower flat belts 11 and 12.
[0004]
[Problems to be solved by the invention]
However, there is no support for the upper and lower flat belts 11 and 12 between the main pressing portion M between the upper and lower rotary press rollers 6 and 8 and the rotary pressing roller 36, and the upper and lower flat belts 11 and 12 The upper and lower flat belts 11 and 12 are in an unstable state between them. Moreover, before the pressing, the adhesive is not melted, so that the cloth and the interlining are still in a state where they are easily shifted from each other. Therefore, the parts sandwiched between the upper and lower flat belts 11 and 12 are likely to wrinkle.
[0005]
When the upper and lower flat belts 11, 12 which are somewhat flexible are sandwiched in the main pressing portion M between the upper and lower rotary press rollers 6, 8, the thickness of the upper and lower flat belts 11, 12 is reduced by the pressing force. The upper and lower flat belts 11 and 12 slightly swell up and down just before the main pressing portion M due to the change in the thickness. However, when such a bulging portion is formed in the upper and lower flat belts 11 and 12, the bulging portion becomes a conveyance resistance, and the upper and lower flat belts 11 and 12 are moved between the main pressing unit M and the rotation pressing roller 36. Are easily wavy in the vertical direction. Therefore, the parts sandwiched between the upper and lower flat belts 11 and 12 in the shape of a corrugation are likely to be wrinkled, resulting in a reduction in commercial value.

[0027]
Next, the operation of the continuous interlining machine will be described focusing on the part pressurizing means constructed as described above.
The part P is obtained by laminating an interlining on a cloth via an adhesive (a large number of adhesive granules or adhesive film sheets). When this part P is placed on the parts supply mounting surface 14a on the nipping and traveling part 14 of the lower flat belt 12 at the part entrance 3 side, the part P is held by the nipping and traveling parts 13, 14 of the upper and lower flat belts 11, 12. The sheet is conveyed in the parts conveying direction D while being sandwiched therebetween. The part P passes between the upper and lower heaters 27 and 28 while being sandwiched between the upper and lower sandwiching traveling parts 13 and 14, and the adhesive in the part P is melted during the transportation.
[0028]
Thereafter, the part P passes through the lower side of the guide roller 39 to reach the circular outer peripheral surface 37 of the rotary pressing roller 36, and the circular outer peripheral surface of the upper rotary press roller 6 while being sandwiched between the upper and lower nipping traveling portions 13 and 14. 9 and the circular outer peripheral surface 37 of the rotary pressing roller 36. The part P is lightly pre-pressed by the sub-pressing section S.
[0029]
Further, the part P is conveyed from the sub-pressing section S along the circular outer peripheral surface 9 of the upper rotary press roller 6. Then, the part P is sandwiched between the upper and lower sandwiching traveling portions 13 and 14 with respect to the main pressing portion M between the circular outer peripheral surface 9 of the upper rotary press roller 6 and the circular outer peripheral surface 10 of the lower rotary press roller 8. While being inserted. The part P is finally pressed by the main pressing part M.
[0030]
Next, since the upper and lower sandwiching traveling portions 13 and 14 are separated in the vertical direction, the part P is separated from the upper and lower sandwiching traveling portions 13 and 14 and carried out. In this case, the upper and lower rotary peeling rollers 15 and 16 prevent the part P from being wound around the upper and lower rotary press rollers 6 and 8.
[0031]
When the piston lot 31a of the driving air cylinder 31 extends, the large lever 30 rotates and the lower rotary press roller 8 separates from the upper rotary press roller 6. When the piston lot 38a of the pressing air cylinder 38 contracts, the small lever 34 rotates, and the rotary pressing roller 36 separates from the upper rotary press roller 6. Therefore, the rollers 6, 8, and 36 are separated from each other, and maintenance can be easily performed.
[0032]
This embodiment has the following features (a) to (c).
(A) In addition to the main pressing portion M between the upper and lower rotary press rollers 6 and 8, a sub-pressing portion S is provided between the upper rotary press roller 6 and the rotary pressing roller 36. Between the parts M and S, the nipping and traveling parts 13 and 14 of the upper and lower flat belts 11 and 12 move while contacting along the circular outer peripheral surface 9 of the upper rotary press roller 6. Therefore, even if the cloth and the interlining are still in a pre-pressurized state where the adhesive is not melted yet and the fabric and the interlining are likely to be displaced from each other, the part P sandwiched between the upper and lower sandwiching traveling portions 13 and 14 is In a stable state along the circular outer peripheral surface 9 of the upper rotary press roller 6 between the pressure parts M and S, the part P is conveyed by being pressed by the main pressure part M, and wrinkles are less likely to occur on the parts P.
[0033]
(B) The pressing force F on the sub-pressing portion S, which is parallel to the expansion / contraction direction E of the piston lot 38 a of the pressing cylinder 38 passing through the axis 35 a of the rotary pressing roller 36, is equal to the rotation of the upper rotary pressing roller 6. It passes on the upstream side in the parts conveyance direction D from the axis 5a. Therefore, when this pressing force F acts on the sub-pressurizing portion S, it acts as the following two types of component forces. First, a normal component force F n acting along the normal connecting the rotation axis 5a of the upper rotating press roller 6 and the axis 5a of the rotary pressure roller 36. The normal force component F n acts as a pre-pressure for pressing against the upper rotary press roller 6 by sandwiching the traveling section 13 and the rotating pressing roller 36 parts P between their upper and lower Ryotaira belt 11 The upper and lower sandwiching traveling parts 13 and 14 and the part P, which are finally pressed by the main pressing part M, are supported between the two pressing parts M and S along the circular outer peripheral surface 9 of the upper rotary press roller 6. . Secondly, a tangential component force F t orthogonal to the normal line. The tangential force F t is both pressing M, pulling the upper and lower clamping travel portion 13, 14 and part P along the circular outer peripheral surface 9 of the upper rotating press roller 6 in the opposite direction with respect to the part transport direction D between S Work as power. Thus, the upper and lower clamping travel portion 13, 14 and part P are pressed along the circular outer peripheral surface 9 while being pulled by a tangential force F t of conveying force of the parts conveying direction D and contrast opposite, both directions The part P is stretched so that the part P is hardly wrinkled.
[0034]
(C) Since the adhesive film sheet before melting is overlapped between the cloth and the interlining, and the adhesive film sheet is melted by the heaters 27 and 28 before the pressing, the bonding between the cloth and the interlining is performed. It will be easier.
[0035]
In addition to the above-described embodiment, the following configurations (a) to (c) may be adopted.
(A) The upper and lower heaters 27 and 28 are omitted in the above embodiment. In this case, a molten adhesive is applied between the cloth and the interlining on the part P to be mounted on the part supply mounting surface 14a of the nipping traveling part 14 of the lower rotary press roller 8.
[0037]
(C) In the above-described embodiment, the lower rotary press roller 8 is connected to the upper rotary press roller 8 in a normal direction connecting the rotary axis 5a of the upper rotary press roller 6 and the rotary axis 7a of the lower rotary press roller 8. 6 is pressurized. The pressing direction of the lower rotary press roller 8 may pass through the eccentric position on the downstream side in the parts conveying direction D from the rotation axis 5 a of the upper rotary press roller 6. In this case, the tangential force of the pressing force acts in the part conveying direction D in addition to the conveying force at the main pressing unit M, and between the pressing units M and S, as in the case of the rotary pressing roller 36 described above. The part P is pulled along the circular outer peripheral surface 9 of the upper rotary press roller 6. Therefore, the part P is stretched along the circular outer peripheral surface 9 by the conveying force and the tensile force in the main pressurizing unit M and the tensile force in the sub-pressurizing unit S, and the parts P are less likely to be wrinkled.
[0038]

[0039]
In addition , both the nipping traveling parts (13, 14) and the part (P) are stretched by the tangential component force (Ft), so that the part (P) is less likely to wrinkle.
[0040]
