Description
いいかえれば、テーブルに押上げバーの収納スペースを設けるとともに、押上げバーそれ自身にカッター刃の入れ込みを許容するスリット等を設ける場合に比して構造を簡素化することができる。
なおこの場合、ベースブロック8の走行変位は、図示のように、シールバーユニット5側に設けたガイドレール12によって案内することが好ましい。
この押上げバー18は、カッター刃6の作用の後、テーブル4をヒータ線13の作用位置まで変位させるに先だって、それをテーブル表面より上方側へ突出させて繰出しフィルム1、2、図に示すところでは、とくに後行繰出しフィルム2を持上げ、この状態でテーブル4を変位させることで、後行繰出しフィルム2の、テーブル4による共連れ、後行繰出しフィルム2の切断端部の巻き込み等を防止するべく機能する。
先行繰出しフィルム1の後端と、後行繰出しフィルム2の先端との連結に当っては、はじめは、図2に示すように、テーブル4上で、先行フィルム1の後端部分と、後行フィルム2の先端部分とを所要量にわたって重ね合わせて配置し、そして、押圧手段17の一対の押えプレート17a、17bをともに下降変位させて、両端部分をそれらのプレート17a、17bをもってテーブル4上に押圧保持するとともに、それぞれの負圧吸着手段21a、21bを作動させて、それらに、両繰出しフィルム1、2を吸着させることによって、両フィルム1、2の、所期した通りの位置決め保持をより確実なものとする。
なおこの場合、カッター刃6によって切断された不要部分の除去は、たとえば、負圧吸引その他によって行うことができる。
なお、テーブル4を、シリンダ14の作動によってヒータ線13の作用位置に変位させるに先だって、押上げバー18をシリンダ19によって、それの進出位置へ上昇変位させることは前述した通りである。
この一方で、押上げバー18は、テーブル4の変位の終了後は、その後退位置に復帰される。
そこで、シールバーユニット5を、シリンダ16によって進出変位させて、図3に示すように、シールバー15をヒータ線13の直上位置にもたらす。
