发明名称 Sewing machine cutting device
摘要 A sewing machine cutting device consisting of a reciprocating blade located in a safe position below the machine work surface, and a descending operative member which urges the material to be cut into cutting relation with said blade. Cutting action is thus achieved without impact (as occurs with a guillotine cutter) and, most important, in a selected width that corresponds to the width of said descending operative member.
