belt, which brings the matrices into the assembler. The spaceband box is positioned above the assembler, the bands dropping almost directly into the assembler. At the end of the moving belt is a rapidly rotating 'star wheel' that gives each incoming matrix or spaceband a small kick to make room for the next one (the star wheel is made of a phenolic-type material to minimize wear of the matrices and bands).

The assembler itself is a rail that holds the matrices and spacebands, with a jaw on the left end set to the desired line width. When
