- each of arms 9 , 10 , 11 is driven in this embodiment in a reciprocating manner in an arc (see arrows A,B,C of FIG. 1B which indicate the arcs along which the free ends of each of arms 9 , 10 , 11 is driven (the drive mechanism is discussed in more detail below).
- each of needle bars 3 , 4 , 5 which are attached, respectively, to arms 9 , 10 , 11
- each needle 1 is also driven in an arc (any desired number of needles may be attached to each needle bar).
- one or more of the needles may be curved. In another example, all of the needles may be curved. In another example, at least one needle may have different radius of curvature than at least one other needle. In another example, all of the needles may have the same radius of curvature. In one specific example, a radius of curvature of a needle may be about 200 mm, in another example 100 mm, and in another example 50 mm.
- use of curved needles may provide for a lighter assembly that runs at a higher speed with a lower parts count.
- presser feet 100 A, 100 B 100 C may be reciprocated (e.g., by a motor) up and down by the components generally identified in FIG. 1A as Portion 100 .
- hooks 2 may be reciprocated (e.g., by a motor) by the components generally identified in FIG. 1A as Portion 200 (see arrows G,H,I of FIGS. 1A and 1B showing the movement of hooks 2 around their respective pivot points).
- each of needles 1 may be driven in an arc to cooperate with hooks 2 and presser feet 100 A, 100 B, 100 C to perform any desired sewing, embroidering, quilting and/or the like.
- a first motor may drive (e.g., reciprocate) arms 9 , 10 , 11 ; a second motor may drive (e.g., reciprocate) presser feet 100 A, 100 B, 100 C; and a third motor may drive (e.g., reciprocate) hooks 2 .

- arms 9 , 10 , 11 may be reciprocated up and down in their respective arcs (e.g., circular arcs) by rotating rods 6 , 7 , 8 (the drive mechanism for rotating rods 6 , 7 , 8 is discussed in more detail below). More particularly, rotating rods 6 , 7 , 8 (which may be reciprocally rotated as shown by arrows D,E,F of FIG. 1B ) may drive arms 9 , 10 , 11 due to each of arms 9 , 10 , 11 being attached to one of rotating rods 6 , 7 , 8 .
- rotating rods 6 , 7 , 8 which may be reciprocally rotated as shown by arrows D,E,F of FIG. 1B ) may drive arms 9 , 10 , 11 due to each of arms 9 , 10 , 11 being attached to one of rotating rods 6 , 7 , 8 .

- each of connector elements 12 , 13 , 14 is connected to tie bar 15 (such that the connector elements move together (see, e.g., FIGS.
- each of rotating rods 6 , 7 , 8 is driven (by one of connector elements 12 , 13 , 14 when the respective clamp is engaged) to rotate back and forth (e.g., in a circular arc) as seen by arrows K,L,M).
- tie bar 15 is driven to reciprocate along arrow J by the action of drive bar 16 (operatively connected at one end to connector element 12 and at the other end to eccentric 17 ).
- eccentric 17 converts the rotary motion shown by arrow N into the motion shown by arrow O associated with drive bar 16 (in one example, the rotation associated with eccentric 17 may be a back-and-forth rotation; in another example, the rotation associated with eccentric 17 may be a rotation in a single direction).
- various components may be driven by one or more motors (e.g., eccentric 17 may be driven by a motor to cause the various movements described above).
- each of connector elements 12 , 13 , 14 may be clamped to each rotating rod 6 , 7 , 8 such that each clamp may be engaged (thus engaging the respective rotating rod 6 , 7 , 8 , to cause the respective rotating rod 6 , 7 , 8 to reciprocate along with the respective connector element 12 , 13 , 14 ) or disengaged (thus disengaging the respective rotating rod 6 , 7 , 8 to allow the respective rotating rod 6 , 7 , 8 to not reciprocate along with the respective connector element 12 , 13 , 14 ).
- each clamp may be hydraulically and/or pneumatically activated (that is, engaged/disengaged).
- each clamp may be activated (that is, engaged/disengaged) under computer control.
- each clamp may be activated (that is, engaged/disengaged) together (that is, all of the arms may be driven to reciprocate at one time).
- each clamp may be activated (that is, engaged/disengaged) independently (that is, one or more of the arms may be driven to reciprocate at one time while one or more other arms may not be driven to reciprocate at that time).
- line 200 which may carry hydraulic and/or pneumatic material (e.g., fluid, air, gas) and contact element 201 (comprising, for example, a clutch element or the like)).
- contact element 201 comprising, for example, a clutch element or the like
- various bearings may be utilized as desired (see, the example bearings 300 A- 300 F of FIG. 3 ). Further, it is seen that, for example, connectors 400 A- 400 F may be utilized to permit quick replacement of a component without removing an entire rotating rod (for example, connector element 12 may be removed and replaced by disconnecting elements 400 C and 400 F from rotating rod 6 ).
- this Fig. shows a front view of a portion of the machine of FIGS. 1A , 1 B, 2 A and 2 B.

- all of the needle bars may be moved together (that is, at the same time in a manner such that movement of one needle bar is not independent from movement of the other needle bars).
- movement of one or more needle bars may be independent from movement of one or more other needle bars (this may be accomplished, for example, by engaging/disengaging one or more clamps as discussed herein).
- independently movable needle bars may be provided in a multiple needle bar machine (and/or method).
- independently movable needle bars provided in a multiple needle bar machine may provide certain distinguishing feature(s) over an independent needle configuration.
- an independent needle configuration may be very complicated (as compared, for example, to the above-mentioned independently movable needle bars configuration).
- an independent needle configuration may have problems with thread coming out of the needle when a given, needle is raised above the work surface (this problem may be reduced or eliminated through use of the independently movable needle bars configuration described herein with reference to various embodiments of the present invention because a non-used needle bar may simply be left at rest).
- independent needles may typically only be implementable on the first needle bar (due, for example, to the size of the implementing pistons and the limited space available in the vicinity of the needle bars (e.g., the limited space available between adjacent needle bars)).
- an independently movable needle bars configuration may be provided via a mechanism that permits one or more needle bars to be lifted up (such that the associated needles would not sew the work surface).
- all of the needle bars may be moved together, but, as just mentioned, one or more of the needle bars may be raised as desired such that the needles associated with the raised needle bar(s) would not sew the work surface.
- the raised needle bar(s) could also be lowered when it was desired that the needles associated with such needle bar(s) would sew the work surface.
- needle bar(s) of this configuration could be raised/lowered using a rack and pinion gear system.
- each needle bar may be electrically, hydraulically and/or pneumatically raised/lowered.
- each needle bar may be raised/lowered under computer control. In another example, each needle bar may be raised/lowered together. In another example, each needle bar may be raised/lowered independently (that is, one or more of the needle bars may be raised at one time (such that the needles associated with the raised needle bar(s) would not sew the work surface) while one or more other needle bars may be left in the lowered position (such that the needles associated with the lower needle bar(s) would sew the work surface).
- the machine may be a computer-implemented machine (e.g., implemented using one or more programmed processors).
- the machine may operate at least in part in an automated manner.
- the method may be a computer-implemented method (e.g., implemented using one or more programmed processors).

- As described herein, in one embodiment the present invention may provide a multi-needle machine utilizing curved needles and/or independent movement of the needle bars.
- Further, as described herein, in one example the present invention may be distinguished from certain conventional systems that, due to considerable inertia of the moving parts (and their complexity) present in such conventional systems, have various shortcomings, including (hut not limited to):
- Relatively limited sewing speed
- Relatively high wear associated with sliding parts
- Impossible to control independently a plurality of needle bars
- Relatively high cost due to quantity and complexity of components
- Further, as described herein, in another embodiment the present invention may provide a multi-needle double chain stitch quilting machine in which the sewing needles are curved to fit a semicircular, oscillating-alternating movement of the needle bars.
- Further, as described herein, in another embodiment the present invention may provide a machine that allows for higher sewing speed due (at least in part) to the lower inertia of the moving parts.
- Further, as described herein, in another embodiment the present invention may provide a machine that allows independent control of two, three (or more) needle bars such that certain patterns (e.g., sewing patterns) that are typically impossible (or very difficult) to accomplish on certain conventional machines (e.g., without independently moveable needle bars such that all needle bars are in movement) may be produced (e.g., produced relatively easily using an embodiment of the present invention).
- Further, as described herein, in another embodiment the present invention may provide a machine that has reduced manufacturing costs.
- Reference will now be made to the Figs.
-
FIG. 1A shows a cross-sectional side view of a machine according to an embodiment of the present invention. Further,FIG. 1B shows various details associated with a portion of the machine as shown inFIG. 1A . - As seen in these
FIGS. 1A and 113 , a free end of each ofarms FIG. 1B which indicate the arcs along which the free ends of each ofarms arms needle bars arms 9, 10, 11) is also driven in an arc. Moreover, of course, as each ofneedle bars needle 1 is also driven in an arc (any desired number of needles may be attached to each needle bar). - In one example, one or more of the needles may be curved. In another example, all of the needles may be curved. In another example, at least one needle may have different radius of curvature than at least one other needle. In another example, all of the needles may have the same radius of curvature. In one specific example, a radius of curvature of a needle may be about 200 mm, in another example 100 mm, and in another example 50 mm.
- Of note, in one embodiment, use of curved needles may provide for a lighter assembly that runs at a higher speed with a lower parts count.
- Still referring to
FIGS. 1A and 1B , it is seen thatpresser feet 100A,100B100C may be reciprocated (e.g., by a motor) up and down by the components generally identified inFIG. 1A asPortion 100. - Still referring to
FIGS. 1A and B, it is seen that hooks 2 may be reciprocated (e.g., by a motor) by the components generally identified inFIG. 1A as Portion 200 (see arrows G,H,I ofFIGS. 1A and 1B showing the movement ofhooks 2 around their respective pivot points). - Thus, as seen, each of
needles 1 may be driven in an arc to cooperate withhooks 2 andpresser feet - Of course, the various components may be driven (e.g., reciprocated) by one or more motor(s). In one example, a first motor may drive (e.g., reciprocate)
arms presser feet arms presser feet - Still referring to
FIGS. 1A and 1B , it is seen thatarms rods rods rotating rods FIG. 1B ) may drivearms arms rotating rods - Referring now to
FIGS. 2A , 2N and 6, certain details regarding howrotating rods rotating rods respective connector element connector elements connector elements FIGS. 2A and 6 where is seen that astie bar 15 reciprocates along arrow (in an essentially linear movement), each ofrotating rods connector elements - Further, it is seen that
tie bar 15 is driven to reciprocate along arrow J by the action of drive bar 16 (operatively connected at one end toconnector element 12 and at the other end to eccentric 17). Of course, eccentric 17 converts the rotary motion shown by arrow N into the motion shown by arrow O associated with drive bar 16 (in one example, the rotation associated with eccentric 17 may be a back-and-forth rotation; in another example, the rotation associated with eccentric 17 may be a rotation in a single direction). - Again, various components may be driven by one or more motors (e.g., eccentric 17 may be driven by a motor to cause the various movements described above).
- In one example, each of
connector elements rotating rod rotating rod rotating rod respective connector element rotating rod rotating rod respective connector element - In another example, each clamp may be activated (that is, engaged/disengaged) together (that is, all of the arms may be driven to reciprocate at one time). In another example, each clamp may be activated (that is, engaged/disengaged) independently (that is, one or more of the arms may be driven to reciprocate at one time while one or more other arms may not be driven to reciprocate at that time).
- Referring now to
FIG. 5 , certain additional details regarding a clamp of the type discussed above is shown (see, e.g., line 200 (which may carry hydraulic and/or pneumatic material (e.g., fluid, air, gas) and contact element 201 (comprising, for example, a clutch element or the like)). - Referring now to
FIG. 3 , it is seen that various bearings may be utilized as desired (see, theexample bearings 300A-300F ofFIG. 3 ). Further, it is seen that, for example,connectors 400A-400F may be utilized to permit quick replacement of a component without removing an entire rotating rod (for example,connector element 12 may be removed and replaced by disconnectingelements - Referring now to
FIG. 4 , this Fig. shows a front view of a portion of the machine ofFIGS. 1A , 1B, 2A and 2B. - Referring now to
FIG. 7A , this Fig, shows a perspective view of a portion of the machine ofFIGS. 1A , 1B, 2A and 2B. - Referring now to
FIG. 7B , this Fig, shows various details associated with a portion of the machine as shown inFIG. 7A . - Referring no to
FIG. 5A , this Fig shows another perspective view of a portion of the machine ofFIGS. 1A , 1B, 2A and 2B. - Referring now to
FIG. 8B , this Fig, shows another perspective view of a portion of the machine ofFIGS. 1A , 1B, 2A and 2B (this view is similar to the view ofFIG. 8A , but with certain parts removed to show other parts). - Referring now to
FIG. 9 , this Fig. shows another perspective view of a portion of the machine ofFIGS. 1A , 1B, 2A and 2B. - Referring now to
FIG. 10 , this Fig, shows a plan view of a portion of a machine with independent needle bars according to another embodiment of the present invention. - As described herein, various embodiments of the present invention may provide for the conversion, of rotating motion (see, e.g., eccentric 17 and arrow N of
FIG. 2A ) to angular motion (see,arms FIG. 1B ). - In one example, all of the needle bars may be moved together (that is, at the same time in a manner such that movement of one needle bar is not independent from movement of the other needle bars). In another example, movement of one or more needle bars may be independent from movement of one or more other needle bars (this may be accomplished, for example, by engaging/disengaging one or more clamps as discussed herein). In another example, independently movable needle bars may be provided in a multiple needle bar machine (and/or method).
- Of note, independently movable needle bars provided in a multiple needle bar machine (and/or method) may provide certain distinguishing feature(s) over an independent needle configuration. For example, an independent needle configuration may be very complicated (as compared, for example, to the above-mentioned independently movable needle bars configuration). In addition, an independent needle configuration may have problems with thread coming out of the needle when a given, needle is raised above the work surface (this problem may be reduced or eliminated through use of the independently movable needle bars configuration described herein with reference to various embodiments of the present invention because a non-used needle bar may simply be left at rest). Further, in practice, independent needles may typically only be implementable on the first needle bar (due, for example, to the size of the implementing pistons and the limited space available in the vicinity of the needle bars (e.g., the limited space available between adjacent needle bars)).
- In another embodiment, an independently movable needle bars configuration may be provided via a mechanism that permits one or more needle bars to be lifted up (such that the associated needles would not sew the work surface). In one example of this configuration, all of the needle bars may be moved together, but, as just mentioned, one or more of the needle bars may be raised as desired such that the needles associated with the raised needle bar(s) would not sew the work surface. Of course, the raised needle bar(s) could also be lowered when it was desired that the needles associated with such needle bar(s) would sew the work surface. In one specific example, needle bar(s) of this configuration could be raised/lowered using a rack and pinion gear system. In another example, each needle bar may be electrically, hydraulically and/or pneumatically raised/lowered. In another example, each needle bar may be raised/lowered under computer control. In another example, each needle bar may be raised/lowered together. In another example, each needle bar may be raised/lowered independently (that is, one or more of the needle bars may be raised at one time (such that the needles associated with the raised needle bar(s) would not sew the work surface) while one or more other needle bars may be left in the lowered position (such that the needles associated with the lower needle bar(s) would sew the work surface).
- In another example, the machine may be a computer-implemented machine (e.g., implemented using one or more programmed processors).
- In another example, the machine may operate at least in part in an automated manner.
- In another example, the method may be a computer-implemented method (e.g., implemented using one or more programmed processors).
- In another example, the method may be carried out at least in part in an automated manner.
