This invention relates to a guide for a sewing machine
particularly designed for use in guiding the rope-like braid
cord from which rugs are made by sewing the cord in
spiral or pseudo-spiral formation.
Heretofore in the sewing of rugs of the type above
indicated at the beginning of the formation of the rug
where the turn of the rope-like material is partially bent

Upon this supporting surface 11, I have provided a
guide plate designated generally 17 which is a generally
?at sheet metal plate with a projecting portion 18 or which
might be thought of having a cutaway portion 19 when
viewed in plan. From the edge of this projecting portion
18, there extends upwardly a work pressing ?n 20‘ which
projects beyond the edge 21 of this portion 18 and is
provided with a tongue 22 which extends downwardly
and enters a slot 23 in the throat plate 10. This slot 23
