(9) there is at least one transverse guiding surface (12)
directed from the nozzle (7) to the side opposite than
adjacent cutter (3).
Description
The invention relates to a device to form fabric tuck-in
selvedges in weaving machines.
Various devices are used to form fabric tuck-in selvedges,
said devices operating on mechanical principle of entrap
ping the ends of woven-in wefts and their mechanical inser
tion into the next opened shed.
All said devices are complicated as to their design, becau se they have to perform a mechanical reverse motion within a short time and along an accurate path. Thus they become demanding as to maintenance and adjustment and they are also expensive.
Further a mechanical and pneumatical device is known, said device being located at the end of the shed, where the in serted weft is tensioned by its end in a suction mechanism and retained by clamping pincers. Between said pincers and the fabric selvedge there is located a pneumatic nozzle be ing directed against the direction of the weft insertion. Between the orifice of the nozzle and the selvedge of the fabric being formed there is pivotally mounted a warp thre ads opening mechanism, said mechanism consisting of a pair of lamellae mounted above each other. After weaving in and cutting the weft, the opening mechanism turns into the newly opened warp threads in the next shed as close to the fabric face as possible. Pneumatic nozzle blows the end of the preceding weft into thus formed guideway in the shed and then the guideway returns back along its path out from the warp threads.
This device shows again the disadvantages of the foregoing mechanical devices and moreover, the nozzle located direct ly against the path of the weft being inserted does not meet the requirement of reliable reversing and inserting the end of the weft into the next shed.

Between said pincers and the fabric selvedge there is located a pneumatic nozzle be ing directed against the direction of the weft insertion. Between the orifice of the nozzle and the selvedge of the fabric being formed there is pivotally mounted a warp thre ads opening mechanism, said mechanism consisting of a pair of lamellae mounted above each other. After weaving in and cutting the weft, the opening mechanism turns into the newly opened warp threads in the next shed as close to the fabric face as possible. Pneumatic nozzle blows the end of the preceding weft into thus formed guideway in the shed and then the guideway returns back along its path out from the warp threads.
This device shows again the disadvantages of the foregoing mechanical devices and moreover, the nozzle located direct ly against the path of the weft being inserted does not meet the requirement of reliable reversing and inserting the end of the weft into the next shed.
Finally a pneumatical device to form tuck-in selvedges is
known, said device consisting of three stationary nozzles
directed under various angles around the weft end, where
their sucessive actuation should form an air flow which
inserts the weft end back into the next shed. However,
blowing-in the weft end what lasts only several minise
conds is in this case very problematic for the reason of
successive actuation of the tuck-in nozzles within a very
short and limited time interval. Forming a successive air
flow affecting the free end of the weft being tuck-in along
its path becomes therefore only a theoretical matter.
The subject matter of the device according to the invention
is that oppositely to the nozzle in front of its orifice
there is formed at least one transversal guiding surface
directed from the nozzle to the side opposite to the ad
jacent cutter. Another feature of the device according to
the invention is that between the nozzle orifice and trans
versal guiding surface in the path of the weft end in the
head there is located at least one brake of the weft end.
The advantage of the device according to the invention is
its simplicity as to the design and technology, simple pro
duction and minimum dimensions. Another advantage of the
device according to the invention is damping of a noncon
trolled motion of the weft in the head prior to its tucking-
in in the next shed by a flow of the pressure fluid. This
results in high quality and evenly tuck-in selvedges of the
fabric. The device according to the invention does not limit
the weaving frequency like mechanical devices and moreover
due to its small dimensions it enables access to the reed
and to the selvedge of the fabric being formed.
The object of the invention is illustrated in the drawings,
where Fig.1 is a schematic plan view of a part of a jet
weaving machine in the place of formed fabric in the moment of the
weft insertion and Fig.2 at the reed beat-up. Fig.3 is
a schematical detail of the device with illustrated outline
of the air flow and motion of the weft end in individual
phases. Fig.4 is an exemplary embodiment in a side view
and Fig.5 is its ground plan. Fig.6 is another embodiment
of the device according to the invention in side view and
Fig.7 is its plan view. Fig.8 is a side view of the devi
ce provided with a couple of gravitational brakes and Fig.9
is their top view. Fig.10 is a side view of an alternative
embodiment of the device with spring-loaded brake and Fig.
11 is its top view.
The device to form tuck-in selvedges in a weaving machine
is located at the edge of the fabric 1 in the place of the
fell 2 between the edge of the fabric 1 and adjacent cutter
3. The device according to the invention is at the inserti
on inlet and end side of the weft 5 being inserted by a
main nozzle 4 located on a stationary part of the weaving
machine. In case of zone weaving, between the central couple
of the devices according to the invention there is another
cutter 3 which is together with said device mounted on a not
shown movable part of the weaving machine, said movable part
of the weaving machine performing a reverse motion away
from the fell 2 of the fabric 1 and back for the reason to
free the path of insertion of the weft 5 during insertion.
In the moment of the weft 5 insertion and the reed 10 beat-
up to the fell 2 of the fabric 1 the central devices accor
ding to the invention and the cutter 3 adjacent thereto are
swung out from the insertion path of the weft 5, except
this time they are aligned with the stationarily mounted
devices according to the invention and the cutter 3 at the
insertion inlet and end side of the weaving machine.
The device according to the invention consists of a head 6
into which leads a not shown supply of the pressure fluid.
The not shown supply of the pressure fluid is connected to
a nozzle 7 situated longitudinally beside the edge 8 of the
fabric 1 with its orifice 9 opposite to the direction of
the reed 10 beat-up. In front of the orifice 9 of the
nozzle 7 there is a slot in the head 6 as shown in Figs
4 and 5, said slot being defined by a pair of surfaces 11
placed above each other, where in each surface there is an
arcuate recess, the outline edge of which forms a transver
sal guiding surface 12, comprising from the viewpoint of
the pressure fluid flow an inlet part 13 and an outlet
part 14. Inlet part 13 of the guiding surface 12 corres
ponds as to the direction with the nozzle7 and the out
let part 14 with a not shown longitudinal axis of the reed 10.
The embodiment according to Figs 6 and 7 has again an accor
dingly situated nozzle 7 like in Figs 4 and 5, only the pair
of surfaces 11 located above each other, has another shape.
The upper surface of the pair of surfaces 11 of the head 6
is inclined towards the orifice 9 of the nozzle 7. A part
of the lower surface of the pair of surfaces 11 is stepped-
up above the orifice 9 of the nozzle 7. In the place of
stepping-up of the lower surface there is a recess in the
head, the outline edge of said recess forms the guiding sur
face 12.
In the not stepped-up part of the lower surface of the pair of surfaces 11 there is a centering projection 15. During weaving, the weft 5, inserted into a not shown warp yarns 16 shed, is beaten-up by the reed 10 to the fell 2 at the face of the fabric 1. Thus the weft 5 gets into the slot between the pair of surfaces 11 to the orifice 9 of the nozzle 7. After interlacing of the inserted weft 5 by the warp yarns 16 and simultaneous removal of the reed 10 from the fell 2 at the face of the fabric 1, the weft 5 is cut- off by cutter 3 from the main nozzle 4, eventually also in the center of the fabric 1 in case of zone weaving. Then a not shown supply of the pressure fluid 17 is opened and said fluid begins to flow out from the orifice 9 of the nozzle 7. Flowing pressure fluid 17 begins to expand and its is direc ted by the inclined guiding surface 12 into the next opened shed. Flowing pressure fluid 17 entrains at the orifice 9 of the nozzle 7 the free end of the weft 5, bends it and tucks it in the next shed, where it is woven-in.
In the not stepped-up part of the lower surface of the pair of surfaces 11 there is a centering projection 15. During weaving, the weft 5, inserted into a not shown warp yarns 16 shed, is beaten-up by the reed 10 to the fell 2 at the face of the fabric 1. Thus the weft 5 gets into the slot between the pair of surfaces 11 to the orifice 9 of the nozzle 7. After interlacing of the inserted weft 5 by the warp yarns 16 and simultaneous removal of the reed 10 from the fell 2 at the face of the fabric 1, the weft 5 is cut- off by cutter 3 from the main nozzle 4, eventually also in the center of the fabric 1 in case of zone weaving. Then a not shown supply of the pressure fluid 17 is opened and said fluid begins to flow out from the orifice 9 of the nozzle 7. Flowing pressure fluid 17 begins to expand and its is direc ted by the inclined guiding surface 12 into the next opened shed. Flowing pressure fluid 17 entrains at the orifice 9 of the nozzle 7 the free end of the weft 5, bends it and tucks it in the next shed, where it is woven-in.
The orifice of the nozzle 7 is located in the weaving pla
ne of the weaving machine. In the embodiment according to
Figs 4 and 5 the ends of the weft 5 enter and get out from
the head 6 of the device when tucking in one plane. In the
embodiment according to Figs 6 and 7 the ends of the wefts
5 are first somewhat lifted by the stepped-up lower surface
of the pair of surfaces 11 and then they slide down towards
the orifice 9 of the nozzle 7. When tucking-in, the pres
sure fluid 17 flown into the transverse guiding surface 12,
while the end of the weft 5 is directed by the projection
15 to the level of the weaving plane. The flow of the pres
sure fluid 17 is utilized better.
In an exemplary embodiment according to Figs 8 and 9, the head 6 is in its upper part provided with a pair of parallel passage grooves 18 directed into the slot in the head 6. In each groove 18 there is inserted a body forming in the slot between the pair of surfaces 11 a brake 19 of the end of the weft 5. The brakes 19 are secured in the head 6 by means of a pin 20 guided in vertical groove 21. In the embodiment according to Figs 10 and 11 in the head 6 there is only one passage groove 18 for one brake 19. Instead of being fixed by pin 20, the brake 19 is secured in the head 6 by a spring 22, while the diameter of the wire of the spring 22 is smal ler than the diameter of the opening 23. The nozzle 7 is in this case inclined and it is directed with its orifice 9 to the brake 19. During weaving, cut ends of the woven-in weft into the slot in the head 6 of the device. But said free ends of the wefts 5 in newly formed fabric 1 are affected by cyclic contracting motion of the fabric 1 after the reed 10 beat-up. This effect shows itself especially with larger setts and larger reed widths. Contraction of the fabric 1 after the beat-up has caused extraction of free ends of the wefts 5 from their original paths. Tuck-in flow of the pres sure fluid 17 did not act on the free ends of the wefts 5 on their necessary length. Now due to the pull of formed fabric 1 the ends of the wefts 5 are pushed under the ope ration surfaces of the brake 19 in the slot of the head 6. The brakes 19 act on the free ends of the wefts 5 by a light pressure, while their required position in the fead 6 of the device is uniformly stabilized. After opening the not shown supply of the pressure fluid 17, the latter flows out from the orifice 9 of the nozzle 7. Flowing pressure fluid 17 begins to expand and it is directed by the transverse guiding surface 12 into the next opened shed. Flowing pres sure fluid 17 overcomes by its kinetic energy the pressing force of the brake 19 holding slightly the free end of the weft 5, entrains it, bends it and tucks it in the following shed where it is woven-in. The brakes 19 can be either of a gravity type, they act on the ends of the wefts 5 in the head 6 by the weight of their mass or their pressure can be induced and adjusted by means of a spring 21, as illustra ted in Figs 10 and 11 by way of an example.
In an exemplary embodiment according to Figs 8 and 9, the head 6 is in its upper part provided with a pair of parallel passage grooves 18 directed into the slot in the head 6. In each groove 18 there is inserted a body forming in the slot between the pair of surfaces 11 a brake 19 of the end of the weft 5. The brakes 19 are secured in the head 6 by means of a pin 20 guided in vertical groove 21. In the embodiment according to Figs 10 and 11 in the head 6 there is only one passage groove 18 for one brake 19. Instead of being fixed by pin 20, the brake 19 is secured in the head 6 by a spring 22, while the diameter of the wire of the spring 22 is smal ler than the diameter of the opening 23. The nozzle 7 is in this case inclined and it is directed with its orifice 9 to the brake 19. During weaving, cut ends of the woven-in weft into the slot in the head 6 of the device. But said free ends of the wefts 5 in newly formed fabric 1 are affected by cyclic contracting motion of the fabric 1 after the reed 10 beat-up. This effect shows itself especially with larger setts and larger reed widths. Contraction of the fabric 1 after the beat-up has caused extraction of free ends of the wefts 5 from their original paths. Tuck-in flow of the pres sure fluid 17 did not act on the free ends of the wefts 5 on their necessary length. Now due to the pull of formed fabric 1 the ends of the wefts 5 are pushed under the ope ration surfaces of the brake 19 in the slot of the head 6. The brakes 19 act on the free ends of the wefts 5 by a light pressure, while their required position in the fead 6 of the device is uniformly stabilized. After opening the not shown supply of the pressure fluid 17, the latter flows out from the orifice 9 of the nozzle 7. Flowing pressure fluid 17 begins to expand and it is directed by the transverse guiding surface 12 into the next opened shed. Flowing pres sure fluid 17 overcomes by its kinetic energy the pressing force of the brake 19 holding slightly the free end of the weft 5, entrains it, bends it and tucks it in the following shed where it is woven-in. The brakes 19 can be either of a gravity type, they act on the ends of the wefts 5 in the head 6 by the weight of their mass or their pressure can be induced and adjusted by means of a spring 21, as illustra ted in Figs 10 and 11 by way of an example.
Described devices according to the invention are only exem
plary embodiments. The devices according to the invention
can be used in all types of weaving machines.
