How a tape edge machine works The table, the carriage, the sew head and the corner. What each part does, and what goes wrong with it. A machine at each stage of a rebuild What a tape edge machine looks like stripped, on the bench, in paint and running under power. New and old style handlebars on the sew head Two photographs, side by side, of the control the operator actually holds all day. The scissor tape edge arrangement Two tables, one operator path, and the layout question it answers. Conveyorized tape edge with a rider A fixed head, a moving mattress, and the automation that turns and flips it.
