Method and apparatus for minimizing sew selvedge
A sewing machine that can be easily set up for minimizing selvedge includes a needle plate assembly and a reciprocating needle. The reciprocating needle is supported above the needle plate for joining at least two pieces of material together. A sew guide is spaced laterally from the reciprocating needle a predetermined distance corresponding to a selvedge length of selvedge extending from the joined material for guiding the pieces of material being joined beneath the needle. A spacer abutting the sew guide laterally spaces the sew guide at the predetermined distance corresponding to the selvedge length.
1. A sewing machine for joining two pieces of material, said sewing machine comprising:
a bed;
a needle plate assembly mounted to said bed;
a reciprocating needle supported above said needle plate assembly for joining at least two pieces of material together;
a sew guide fixed to said bed and spaced laterally from said reciprocating needle a predetermined distance corresponding to a predetermined selvedge length of selvedge extending from at least one of the at least two pieces of material for guiding the pieces of material being joined beneath said needle;
a spacer abutting said sew guide and laterally spacing said sew guide at said predetermined distance corresponding to the predetermined selvedge length, said spacer being a needle guide having an opening which guides said needle; and
an outer foot laterally spaced from said sew guide for securing the material against said needle plate assembly as said needle is received through said opening.
2. The sewing machine as in claim 1 , in which said spacer moves relative to said sew guide prior to being fixed to said bed.
3. The sewing machine as in claim 1 , in which said spacer has a wear surface laterally spaced from said needle at said predetermined distance corresponding to the predetermined selvedge length, and said wear surface abuts said sew guide to laterally space said sew guide at said predetermined distance.
4. The sewing machine as in claim 1 , in which said predetermined distance is up to about 7 mm.
5. The sewing machine as in claim 1 , in which said predetermined distance is less than about 5 mm.
6. The sewing machine as in claim 1 , in which said needle plate assembly includes a feed dog disposed beneath said needle, and said spacer secures the material against said feed dog.
7. The sewing machine as in claim 6 , in which said spacer extends laterally from said needle a distance at least equal to said predetermined distance.
8. A method of setting up a sewing machine to form a selvedge having a predetermined selvedge length in an article sewn on the sewing machine, the sewing machine having a reciprocating needle supported above a needle plate assembly mounted to a bed, a laterally adjustable sew guide spaced laterally from the reciprocating needle for guiding the article beneath the needle, and an outer foot laterally spaced from said sew guide for securing the material against said needle plate assembly, said method comprising:
fixing said sew guide to the bed; and
providing a spacer abutting said sew guide and laterally spacing the needle from the sew guide a distance corresponding to the predetermined selvedge length, said spacer being a needle guide having an opening which guides said needle.
9. The method as in claim 8 , in which said sew guide is fixed relative to said needle by adjustably fixing said sew guide to a bed forming part of the sewing machine.
10. The method as in claim 8 , in which said spacer is selected from a group of spacers which space said sew guide from said needle different distances.
11. A method of joining two pieces of material, said method comprising:
positioning a first piece of material over a second piece of material;
aligning an edge of said first piece of material with an edge of said second piece of material;
engaging said edges with a sew guide laterally spaced from a reciprocating needle by a spacer abutting said sew guide and laterally spacing said sew guide a distance equal to a desired selvedge length of a selvedge formed between a seam created by said reciprocating needle and said material edges, said sew guide being fixed to a bed disposed beneath said needle and said spacer being a needle guide having an opening which guides said needle;
securing said first and second pieces of material against said needle plate assembly using an outer foot laterally spaced from said sew guide; and
sewing said first and second pieces of material together using said needle to form selvedges extending from said seam to said edges.
12. A method of joining two pieces of material, said method comprising:
positioning a first piece of material over a second piece of material;
aligning an edge of said first piece of material with an edge of said second piece of material;
engaging said edges with a sew guide laterally spaced from a reciprocating needle by a spacer laterally spacing said sew guide a distance equal to a desired selvedge length of a selvedge formed between a seam created by said reciprocating needle and said material edges;
sewing said first and second pieces of material together using said needle to form selvedges extending from said seam to said edges, including fixing a longitudinal edge of an elongated third piece of material to at least one of said selvedges, covering said edges of said first and second pieces of material with said third piece of material, and fixing an opposing longitudinal edge of said third piece of material to one of said first and second pieces of material.
13. The method as in claim 12 , in which at least one of said longitudinal edges of said third piece of material is fixed by sewing.
14. An article comprising:
a first piece of material having a selvedge extending from a seam to an edge of the material;
a second piece of material having a selvedge extending from said seam to an edge of said second material, said second piece of material being fixed to said first piece of material along said seam;
a third piece of material covering said edges, and having a first longitudinal edge fixed to at least one of said selvedges on one side of said seam and a second longitudinal edge fixed to one of said first and second pieces on an opposite side of said seam.
15. The article as in claim 14 , in which at least one of said longitudinal edges is fixed by sewing.
16. The article as in claim 14 , in which said first longitudinal edge is fixed to said at least one of said selvedges along said seam.
17. A kit for use with a sewing machine suitable for joining two pieces of material, said sewing machine including a needle plate assembly, a reciprocating needle supported above the needle plate mounted to a bed for joining at least two pieces of material together, a sew guide spaced laterally from the reciprocating needle a predetermined distance corresponding to a predetermined selvedge length of selvedge extending from at least one of the at least two pieces of material for guiding the pieces of material being joined beneath said needle, and an outer foot laterally spaced from said sew guide for securing the material against said needle plate assembly, said kit comprising:
at least two spacers defining different predetermined distances corresponding to different predetermined selvedge lengths, wherein, in use, one of said spacers is abutting said sew guide fixed to said bed and laterally spaces said sew guide at said predetermined distance defined by said one of said spacers, said spacers being needle guides having an opening which guides said needle.
18. The kit as in claim 17 , in which one of said spacers defines a predetermined distance of no more than about 5 mm.
