NEEDLE BED FOR CIRCULAR KNITTING MACHINE, AND CIRCULAR KNITTING MACHINE INCLUDING SAME NEEDLE BED

The present invention provides a needle bed for a circular knitting machine in which, an insert piece for forming a groove for slidably storing the knitting tool, the contact area between the knittingtool and the insert piece is reduced. A needle bed which is mountable to the circular knitting machine is configured to slidably store a knitting tool in a groove of which both side surfaces are formed by opposed plate surfaces of adjacent insert pieces (50) having a rectangular plate shape, wherein each insert piece (50) has a plurality of dimples (53) formed in a short-side direction (X) and along-side direction (Y) on the plate surfaces. 提供一种圆型针织机的针床，其中，不用很大地改变针织工具或插入件(该插入件形成以可滑动的方式安装针织工具的槽)的结构本身，减少插入件与针织工具之间的接触面积。在可设置于圆型针织机中的针床中，在邻接的长方形板状的插入件(50)的相对的板面为两个侧面的槽中，以可滑动的方式安装针织工具，插入件(50)在上述板面的短边方向(X)和长边方向(Y)设置有多个凹部(53)。
