Apparatus for guiding and braking bands in sewing machines

In a sewing machine, particularly in a household sewing machine, the combination of a support with an apparatus for guiding and braking bands which are to be sewn to pieces of fabric or like commodities, said apparatus comprising an elongated tubular housing defining a transversely extending channel for a band, means for varying the effective width of said channel, said varying means being movably carried by said housing at one side of said channel, guide means for commodities, said guide means being disposed at the other side of said channel and being movably mounted on said housing, and means for biasing the band in said channel against said housing with a variable force.

The combination of claim 10, wherein said biasing means is installed in said housing for movement up and down away from and toward a band in said channel.

Apparatus for guiding and braking bands which are to be sewn to pieces of fabric or like commodities in a sewing machine, comprising a housing defining a transversely extending channel for a band, said housing including an elongated U-shaped bottom section having a pair of upwardly extending legs and an inverted U-shaped top section having a pair of downwardly extending legs, each leg of one of said pairs at least partially overlying a leg of the other of said pairs and said legs having registering openings which define said channel;

• and means for varying the effective width of said channel.

Apparatus for guiding and braking bands which are to be sewn to pieces of fabric or like commodities in a sewing machine, comprising a housing defining a transversely extending channel for a band, said housing including a top section and a bottom section, and said sections defining a passage extending transversely of said channel;

• and means for varying the effective width of said channel, said varying means including a portion which is reciprocably received in said passage at one side of said channel, and said portion of said varying means having a substantially U-shaped crosssectional outline and including two spaced-apart prongs

Apparatus for guiding and braking bands which are to be sewn to pieces of fabric or like commodities in a sewing machine, comprising a housing defining a transversely extending channel for a band;

• means for varying the effective width of said channel, said varying means being supported by said housing for movement relative thereto;
• and means for biasing the band in said channel, said biasing means including a substantially plate-like member overlying the band in said channel and means for moving said plate-like member toward and away from the band in said channel.
