Abstract
Description
以下、本発明の第1実施形態を図面に基づいて説明する。図1は、本実施形態に係る編み機1(図2)により編成された編成物2の一例を示す図である。図1に示すように、編成物2の形状は、立体形状である。編成物2は、その内部が空洞ではなく、編成物2を構成する編糸3によって内部が詰まった状態である。このため、編成物2に対して外部から力を加えた場合(例えば、編成物2を台に載置した状態で編成物2を押しつぶす力を加えた場合)であっても、内部が空洞の場合と比較して、その形状が変形しにくい。本実施形態に係る編み機1は、図1で例示する編成物2のように、1枚の編地からなる平面的な形状ではなく、立体的な形状であり、かつ、編糸3によって内部が詰まった状態の編成物2を編成する装置である。なお、本実施形態では、編地において、一のループに対して、いわゆるウェール方向に他のループが通った状態を「編目」と表現している。また既に形成されている一のループに対して編糸を通すことを「編目を編成する」と表現している。編目が編成されると、新たなループが形成されることになる。また、ループ状の編糸であって、他のループが通る対象となるものを「ループ」と呼んでいる。新たなループが通っていないものも、既にループが通っているものも「ループ」に相当する。
次に第1実施形態の変形例について説明する。
次に、第2実施形態について説明する。以下の第2実施形態の説明において、第1実施形態の要素と同一の要素については、第1実施形態で付与した符号と同一の符号を付与し、詳細な説明を省略する。
次に第2実施形態の変形例について説明する。第2実施形態では、図41~45で示すケースのように、対編み針101の対フック122に係止するループを対保持部146に目移しする際、図43で示すように、対編み針101(図43の例では第1前方対編み針FA1)が、凹み部131内を延在する編糸3(図43の例では後方二段目左右延在部位153)よりも上方に位置するようにしていた。しかしながら、図66で示すように、対編み針101が編糸3の下方に位置するようにしてもよい。図66の状態から前方編み針ユニット105を前方へ移動させると、編糸3によって対ベラ110が閉状態となり、編糸3を対フック122内に進入させることなく、ループを対保持部146に係止させることができる。なお、後方二段目左右延在部位153には、給紙機構によりこの位置に留まらせようとするテンションが加わっているため、図66の位置に留まった状態となる。
