Chapter 44: Glossary of Embroidery Machine Terms q Arm machine Multi-head embroidery machine driven by a single main shaft. Each sewing head is attached to the shaft, usually by gears. Sewing heads resemble industrial sewing machines in the "arm" that the needle case is attached to. q Automatic color change The ability of a multi-needle commercial embroidery machine to follow a command to change to another specified needle. q Bobbin case Small, round metal device for holding the bobbin. Used to tension the bobbin thread. Inserted in the hook for sewing. q Bridge machine Embroidery machine with two shafts, one for the hook assembly and one for the needle assembly. Sewing heads are suspended from a beam allowing for larger sewing fields than an arm machine. Bridge machines are accessible from both the back and front of the machine through the "bridge". q Cap frames Specialized embroidery frames (hoops) designed to hold finished caps for embroidering. Available in a variety of styles for various machines, with two basic styles being to sew the finished cap flattened out (for use on a flat machine) or sew the finished cap in its natural curve (for use on a tubular machine). q Check spring Assists in upper thread tensioning and is used to detect upper thread breaks in many embroidery machine models. q Cylinder arm machine Refers to machines with "cylinder" beds. The hook assembly is housed in a cylinder-shaped arm, allowing goods to curve around the cylinder for embroidery. q Disk reader An external or internal device used to read machine movements from either a 5.25" or 3.5" computer disk. q Embroidery point Unit of measurement in embroidery, in which 10 points equals 1 mm. q Flat embroidery Embroidery (usually on cut panels or patches) that is framed in hoops exclusively on the top of the embroidery machines hook assembly. q Framing press Machine to aid the framing process. q Frame sash Part of the pantograph to hold the frames. Also called a sash. Varieties of sash types include: border, frame, tubular, cap and sock. q Hook assembly Rotary device designed to pass the needle at a given point in the needle bar rise. The hook point passed into a thread loop formed by the rising needle bar and pulls the thread around the bobbin case to form a lock stitch. q Hooping board Board designed to hold the outer portion of the hoop while the goods to be embroidered are placed over the board to be hooped. Once the goods are aligned and placed correctly over the outer hoop, the operator inserts the inner portion of the hoop. q Jumbo rotary hook Rotary hook which holds a bobbin case with a much larger thread capacity than a standard hook. 104
