Longarm quilting is the process by which a longarm sewing machine is used to sew together a quilt top, quilt batting and quilt backing into a finished quilt.. A complete longarming system typically consists of a sewing machine head, a frame, a table with a layer of plastic (under which is placed a pantograph), and several rollers on which the fabric layers and batting are attached.

A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...

It is not possible to create perfectly straight line motion using a four-bar linkage, without using a prismatic joint. Watt's linkage (1784)
This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.
Although this design predates Second World War, records of German paratroopers having genuinely been issued pantographic knives have not surfaced. To complicate identification, samples made with German army markings (brass handles with text in English language) seem to be post-war (1948) marketing attempts capitalizing on the term paratrooper .
