方向と同方向へ移動自在に配設し、該８押圧部（Ｉｌａ
）がその最大突出時に各シール面（３ａ）より包装フィ
ルム移送路（ａ）側へ突出するように配置すると共に、
各抑圧部（１１ａ）をスプリング等の弾性材（１２）に
より常時包装フィルム移送路（ａ）側へ弾圧せしめる。
また、各押圧部（ｌｌａ）内には冷却用エアが供給され
る通気路（１１ｂ）を開設し、該通気路（Ｉｌｂ）から
下流側のシール面（３ａ）前方へ向けて吐出孔（１１ｃ
）を複数個開穿する。
次に、斯る製袋充填包装装置の作動について説明する。
先ず、自移動体（６Ｈ６）を相互に閉動させ上部クラン
プ（７）（７）の押圧面（７ａ）（７ａ）問に包装フィ
ルム（Ａ＞を移動不能に挟持した状態において、被包装
物（Ｂ）の充填を開始し、これを両袖包装物受け（８）
（８）により支持する（第１図）。
その後、自移動体（６）（６）を相互に開動して、上部
クランプ（７）（７）による挟持を開放さＵ、繰り出し
ベルト（２）（２）を駆動させて包装フィルム（Ａ）を
所定長さ繰り出１（第２図）。
そして、包装フィルム（Ａ＞の繰り出しが終了すると、
両横シールＩＩＩ（３）（３）を相互に開動して二ケ所
平行に熱シールすると共に、下部クランプ（ｉｔ）（１
１）の押圧部（１１ａ）（１１ａ）間に下流側の袋体（
Ａ４）を移動不能に挟持した後、カッター（４）を前進
させ上下の袋体（Ａ３　）（Ａ４　）を切断分離する。
また、これと同時又は終了模に自移動体（６）（６）を
相互に開動して上部クランプ（７）（７）の押圧面（７
ａ）（７ａ）間に上流側の袋体（Ａ３）を移動不能に挟
持する（第３図）。
その後、両横シール機（３）（３）のｆｆｔｌ動を開始
すると同時にエアシリンダ等の駆動源（１０）を駆動し
てたくし上げガイド（９）及び後退させた一方の冷却体
（５）を前進させる。
先にたくし上げガイド（９）が上流側の袋体（Ａ３）に
突ぎ当ってこれを略くの字状に折り曲げ、これに伴って
該袋体（Ａ３）下端のシール部（Ａ＋　）が上昇）゛る
。
この時、たくし上げガイド（９）の噴出孔（９Ｃ）から
圧縮エアを噴出して該シール部（Ａ１）を押し下げ、次
いで一方の冷却体（５）の冷却面（５ａ）がこのたくし
上げたシール部（Ａ１）に当接し、他方の冷却体（５）
の冷却面（５ａ）とで挾み込み冷却ｕしめる（第４図）
。
また、下流側の袋体（Ａ４）は両横シール機（３）（３
）の開動が開始されても弾性材（１２）（１２）により
下部クランプ（１１）（１１）の押圧部（ｌｌａ）（１
１ａ）を突出させて挟持し続けており、この時これら押
圧部（１１ａ）（１１ａ）の吐出孔（１１ｃ）（１１ｃ
）から冷１１用エアを噴出して上端のシール部（Ａ２）
を冷却せしめる。
その後、たくし上げガイド（９）及び一方の冷却体（５
）のみを後退させて初期状態に戻り、上述した工程を繰
り返すか、或いはこの状態のまま停止させる。
従って、本実施例のものは停止状態で冷却体（５）（５
）が横シールＩｆｉ（３）（３）と離れているため、横
シール機（３）（３）からの熱を受は難く冷却体（５）
（５）の温匹上貸を防止できる。
尚、前示実流例では移送手段がたくし上げガイド（９）
であったが、これに限定されず繰り出しベルト（２）（
２）を再駆動してシール部（Ａ１）を冷却体（５）（５
）間に移動させても良い。
この際、繰り出しベルト（２）（２）を包装フィルム繰
り出し方向へ駆動させる場合には冷却体（５）（５）を
横シール４ｍ（３）（３）の下流側に配設し、包装フィ
ルム繰り出し方向と逆方向へ駆動させる場合には冷却体
（５）（５）を横シール機（３）（３）の上流側に配設
する。
また、包装フィルム（Ａ）に圧縮エアを当ててシール部
（Ａ１）を冷却体（５）（５）間に移動させても良い。
更に、袋体（Ａ３）下端のシール部（Ａ１）のみを冷１
１体（５）（５）により冷ＵＩＬ、だが、袋体（Ａ４）
上端のシール部〈Ａ２）を同様に冷却しても良いことは
言うまでしない。
〈発明の効果〉 本発明は上記の構成であるから、以下の利点を有する。
■　熱シール直後横シール機の開動に伴い移送手段、詳
