Abstract

A system for folding a ribbon stock, the system including: a transferring unit; a guide member having a passage for guiding the ribbon stock, the passage defining a longitudinal axis; a folding means supported to revolve and move in a direction substantially transverse to the longitudinal axis for applying a force against the ribbon stock passing through the guide member; a driving means; a supporting frame; a fixing body having a predetermined length and a guide entrance operatively connected with the guide member, wherein ends of the fixing body are rotatably fixed to the supporting frame, the fixing body having a guide slot formed therein for insertably receiving the folding means; and a pair of rotary bodies rotatably connected to the ends of the fixing body for revolving the folding means, the pair of rotary bodies configured to insertably receive the folding means.

Claims

1. A system for folding a ribbon stock, the system comprising:

a transferring unit for transferring the ribbon stock;

a guide member having a passage for guiding the ribbon stock during transfer by said transferring unit, the passage defining a longitudinal axis;

a folding means supported to revolve and move in a direction substantially transverse to the longitudinal axis for applying a force against the ribbon stock passing through said guide member, said folding means positioned adjacent said guide member, and for folding the ribbon stock to a predetermined angle;

a driving means configured to engage said folding means, for revolving and moving said folding means against the ribbon stock;

a supporting frame comprised of at least two plate shaped members, said guide member positioned between the at least two plate shaped members;

a fixing body having a predetermined length and a guide entrance operatively connected with said guide member,

wherein ends of said fixing body are rotatably fixed to said supporting frame, said fixing body having a guide slot formed therein for insertably receiving said folding means; and

a pair of rotary bodies rotatably connected to the ends of the fixing body for revolving the folding means, said pair of rotary bodies configured to insertably receive the folding means.

2. The system of claim 1, wherein said folding means comprises at least one elongate member.

3. The system of claim 2, wherein said at least one elongate member has a substantially triangular cross-section.

4. The system of claim 1, wherein said guide entrance further comprises

an elastic support means for moving the ribbon stock in a predetermined channel.

5. The system of claim 1, wherein said driving means comprises:

a first toothed portion set on said pair of rotary bodies;

a second toothed portion set on a rotating shaft installed on said supporting frame, said second toothed portion configured to mesh with said first toothed portion; and

a servo motor coupled to the rotating shaft for rotating the rotating shaft.

6. The system of claim 1, further comprising

a cutting means for cutting the ribbon stock supplied from said transferring unit in a length substantially corresponding to the sheet material molding configuration.

7. The system of claim 1, wherein the folding means are configured and dimensioned for connecting said pair of rotary bodies to each other through guide holes of said pair of rotary bodies and the guide slot of said fixing body.

8. A method of folding ribbon stock, comprising:

transferring ribbon stock through a passage formed by a guide, the passage defining a longitudinal axis;

rotating at least one rotary assembly in an arcuate motion relative to the guide from a first position toward at least one second position to fold a portion of the ribbon stock; and

coupling the at least one rotary assembly to a pair of elongate members such that said rotating at least one rotary assembly causes the pair of elongate members to revolve and move in a direction substantially transverse to the longitudinal axis for applying a force against the portion of the ribbon stock,

wherein the at least one rotary assembly includes first and second rotary bodies spaced to receive the ribbon stock therebetween, and

wherein the pair of elongate members engages the first and second rotary bodies.

9. The method of claim 8, wherein the longitudinal plane has a first side and a second side opposite the first side relative to the plane, the method further comprising:

positioning each elongate member of the pair of elongate members on each side of the first side and the second side.

10. The method of claim 8, wherein the pair of elongate members engages the first and second rotary bodies by

inserting the pair of elongate members into the first and second rotary bodies for mutual connection of the first and second rotary bodies.

11. The method of claim 10, wherein said rotating the at least one rotary assembly in an arcuate motion includes

revolving the pair of elongate members by rotating together the pair of rotary bodies mutually connected by the pair of elongate members.

12. An apparatus for folding a metallic ribbon stock, the apparatus comprising:

a transferring unit for transferring the ribbon stock;

a guide member having a passage for guiding the ribbon stock during transfer by the transferring unit;

folding means, supported such that it may be revolved and moved in a straight line direction for applying a force against the ribbon stock passing through the guide member, the folding means positioned adjacent said guide member, and for folding the ribbon stock to a predetermined angle;

driving means configured to engage said folding means, for revolving and driving the folding means against the ribbon stock;

a supporting frame comprised of at least two plate shaped members, the guide member positioned between the at least two plate shaped members;

a fixing body having a predetermined length and a guide entrance operatively connected with said guide member,

wherein ends of the fixing body are rotatably fixed to the supporting frame, the fixing body having a guide slot formed therein for insertably receiving said folding means; and

a pair of rotary bodies, rotatably connected to the ends of the fixing body for revolving the folding means, said pair of rotary bodies configured to insertably receive the folding means.

13. The apparatus of claim 12, wherein said fixing body further includes:

a folding body; and

annular support portions configured to fixedly attach said folding body to said supporting frame,

wherein the guide slot configured for insertably receiving said folding means is formed on said annular support portions.

14. The apparatus of claim 12, wherein said pair of rotary bodies includes

guide holes to insertably receive the folding means.
