Problems to be solved by the invention

However, the bayonet temple in the conventional device is configured such that the outer diameter of each housing portion of each bayonet ring temple is smaller than the outer diameter of the inner rod. Therefore, in this conventional device, the woven fabric is in the following state: the fabric is wound around the barbed temple in a state of being inclined with respect to the axis of the barbed temple, not being parallel, from the inner bar side toward the end of the barbed temple. In addition, the loop temple is configured to obtain a desired gripping force in a state where the fabric is sufficiently penetrated by the needles in all the temple loops. However, in this loop temple, if the fabric is wound in an inclined state as described above, the degree of penetration of the needle into the fabric may be insufficient on the inner rod side, and as a result, the fabric may not be sufficiently gripped.

Further, in the stab-pin temple, a stab-pin temple configured such that the outer diameter of each housing portion is larger than the outer diameter of the inner rod may be considered. However, in this case, the fabric is not sufficiently gripped by the inner bar, the bottom plate, and the cover in some cases.

In view of the above circumstances, an object of the present invention is to provide the following structure: in a stab-bar temple used in a full-width temple device of a loom, the held woven fabric can be more sufficiently gripped.

Means for solving the problems

The present invention is premised on a bar temple for a loom, which is used for a full-width temple device of a loom and on which a woven fabric is wound, wherein the bar temple is constituted by a round bar-shaped inner bar and bar temples provided continuously to both sides of the inner bar, and each of the bar temple includes a cylindrical housing portion and a temple ring on which a plurality of needles are implanted, and is constituted such that a plurality of the temple rings are held between a pair of the housing portions on the inner bar side and the end portion side.

In order to achieve the above object, the stab-type temple according to the present invention is characterized in that the outer diameter of the portion of each of the stab-type temples where the fabric is wound is substantially the same as the outer diameter of the inner lever, in the case portion on the inner lever side and the case portion on the end portion side.

The effects of the invention are as follows.

According to the stab-bar temple of the present invention, in the full-width temple device, the fabric is wound around each of the stab-ring temples in a state parallel to the axis thereof. In this state, the woven fabric is sufficiently inserted by the needles of all the temple rings in the respective loop temple. As a result, the hook temple grips the fabric with a desired gripping force. Thus, the barbed temple according to the present invention can hold the woven fabric more sufficiently.

Detailed Description

Hereinafter, an embodiment of a full temple device including the stab-bar temple of the present invention will be described with reference to fig. 1 to 7.

As shown in fig. 1, in the loom 1, the full temple device 2 is provided in the vicinity of the cloth fell CF on the side opposite to the reed 3 side (the side of the warp row T) with respect to the cloth fell CF so as to extend over the cloth fell of the woven cloth W to be woven. The loom 1 further includes a front upper stay 8 as a beam member extending between left and right side frames (not shown). A plurality of brackets 4 are attached to the front upper stay 8 at intervals in the weaving direction. Further, the full-width temple device 2 is supported by the front upper stay 8 via the plurality of brackets 4.

Further, in the loom 1, the mounting rod 5 longer than the full-width temple device 2 is attached to the plurality of brackets 4 attached to the front upper stay 8 as described above. Furthermore, the loom 1 includes cutting devices 6 and 7 for cutting the weft inserted on the yarn feeding side and the yarn opposite side, respectively. The cutting devices 6 and 7 are attached to the attachment rods 5 provided as described above, and are disposed in the vicinity of both ends of the full temple device 2 in the weaving direction.

As shown in fig. 2, the full temple device 2 includes, as its main components: a base body 10 including a bottom plate 10a attached to the bracket 4; a cover 11 attached to the base plate 10 a; and a stab-bar temple 13 as a temple bar, which is housed in the space 12 defined by the bottom plate 10a and the cover 11.

The base 10 is mainly composed of a bottom plate 10a as a long member extending over the width of the woven fabric W. The bottom plate 10a is composed of: an attached portion 10a1 which is a portion attached to the bracket 4 and to which the cover 11 is attached; and a chassis-side guide portion 10a2 that delimits the space 12 for housing the stab-bar temple 13 with the cover 11 as described above and guides the woven fabric W by cooperation with the stab-bar temple 13.

The bottom plate 10a is configured such that the attached portion 10a1 is formed in a substantially plate shape, and has a rectangular shape having a dimension in the longitudinal direction sufficiently longer than a dimension in the lateral direction when viewed in the plate thickness direction. The chassis-side guide portion 10a2 is integrally formed with the attached portion 10a1 so as to be continuous with the attached portion 10a1 at one end in the short-side direction and to be present in the long-side direction. The chassis-side guide portion 10a2 is formed to have a substantially arc shape when viewed in the longitudinal direction, and one side of one end surface in the plate thickness direction of the attached portion 10a1 is a curved inner surface.

In the illustrated example, the bottom plate 10a has an engaging portion 10a3 that engages with the cover 11. The engaging portion 10a3 is formed as follows: the side surface of the attached portion 10a1 protrudes and is located in the longitudinal direction with respect to the attached portion 10a1, that is, in the width direction of the bottom plate 10 a. The engaging portion 10a3 is formed in a substantially L-shape as follows: the portion on the tip end side extends toward the base-side guide portion 10a2 in the short-side direction with respect to the portion protruding from the attached portion 10a 1.

The cover 11 is configured to include: a mounting portion 11a which is a portion of the bottom plate 10a mounted in the base body 10; and a hood-side guide 11b that delimits the space 12 for housing the stab-bar temple 13 with the bottom plate 10a as described above and guides the woven cloth W by cooperation with the stab-bar temple 13.

In the structure of the cover 11, the mounting portion 11a is formed in a plate shape, and when viewed in the plate thickness direction, it is an elongated rectangular portion having a dimension in the longitudinal direction substantially equal to the dimension in the longitudinal direction of the mounted portion 10a1 of the bottom plate 10 a. The hood-side guide portion 11b is formed in a substantially plate-like shape, and has an elongated rectangular shape whose dimension in the longitudinal direction coincides with the dimension in the longitudinal direction of the attachment portion 11a when viewed in the plate thickness direction. The hood-side guide 11b is present in the hood 11 in a state in which the longitudinal direction thereof coincides with the longitudinal direction of the mounting portion 11 a. Therefore, the cover 11 as a whole has a dimension in the width direction, which is the longitudinal direction of the mounting portion 11a, substantially equal to the dimension in the width direction of the bottom plate 10 a.

In order to define the space 12 as described above in a state where the cover 11 is attached to the bottom plate 10a, the cover-side guide portion 11b has a portion (facing portion) facing the chassis-side guide portion 10a2 in the bottom plate 10a in the plate thickness direction. In other words, the cover 11 is formed in the following size: in the front-rear direction, which is the short-side direction of the end surface of the attachment portion 11a, in a state of being attached to the base plate 10a, a portion on the tip side (the side opposite to the attachment portion 11a side) of the cover-side guide portion 11b becomes the facing portion facing the base-side guide portion 10a2 in the base plate 10 a. Incidentally, in the illustrated example, the dimension of the cover 11 in the front-rear direction is substantially the same as the dimension of the bottom plate 10a in the front-rear direction, which is the short side direction of the attached portion 10a 1. In the hood-side guide 11b, the facing portion facing the chassis-side guide 10a2 as described above is formed to be gently curved when viewed in the width direction.

The cover 11 is formed such that the position of the mounting portion 11a in the plate thickness direction is different from the position of the cover-side guide portion 11b so that the cover-side guide portion 11b does not interfere with the engagement portion 10a3 in the bottom plate 10a when the mounting portion 11a is mounted on the bottom plate 10 a. The cover 11 has a connection portion 11d extending from the attachment portion 11a in the plate thickness direction and connecting the attachment portion 11a and the cover-side guide portion 11 b. However, the positional relationship between the mounting portion 11a and the cover-side guide portion 11b is: the inner side surface of the portion bent as described above of the facing portion of the hood-side guide portion 11b faces the mounting portion 11a side in the plate thickness direction.

Further, the cover 11 has an engaged portion 11c that engages with the engaging portion 10a3 in the bottom plate 10a of the base 10. The engaged portion 11c is formed to protrude from an end surface of the cover side guide portion 11b on the inner surface side in the plate thickness direction, and is formed to exist in the width direction of the cover 11. The engaged portion 11c is formed in a substantially L-shape as follows: the portion on the front end side extends toward the mounting portion 11a in the front-rear direction with respect to the portion protruding from the hood-side guide portion 11 b.

The position of the engaged portion 11c is such that a surface of the engaged portion 11c facing the distal end side of the hood-side guide portion 11b and the inner surface of the hood-side guide portion 11b are continuous with each other in the front-rear direction. The engaged portion 11c is formed such that a surface continuous with the inner surface of the cover-side guide portion 11b is curved with substantially the same curvature as the inner surface. Therefore, the engaged portion 11c also forms the space 12 in the cover 11.

As shown in fig. 3, the bayonet temple 13 is composed of an inner pole 14 and bayonet temple members 15, the inner pole 14 is formed of a round bar-shaped member, and the bayonet temple members 15, 15 are provided continuously with both sides of the inner pole 14. Each of the grommet-type temples 15 itself has the same structure as a general grommet-type temple. Specifically, each of the barbed temple 15 includes: a plurality of temple rings 16; a pair of housing portions 18, 18 arranged to sandwich the plurality of temple rings 16 therebetween; and a support shaft 17 supporting each temple ring 16 and each housing portion 18.

In the structure of each of the bayonet temple 15, each temple ring 16 is a disk-shaped member having a through hole (not shown) at the center thereof, and a plurality of (a plurality of) needles 16a are implanted so as to protrude from the outer peripheral surface thereof. The through-hole in each temple ring 16 is formed in an aperture through which the support shaft 17 can be inserted.

Each housing portion 18 is a cylindrical member and has a through hole 18a formed to penetrate therethrough in the axial direction thereof. The diameter of the through hole 18a in each housing portion 18 substantially matches the diameter of the support shaft 17. In each case 18, one end surface in the axial direction is an inclined surface inclined with respect to a direction perpendicular to the axial line.

In each of the barbed temple 15, the plurality of temple rings 16 are provided on the support shaft 17 in a state of being supported by the support shaft 17 inserted through the through hole thereof. However, each side stay 16 is supported by a bushing member (not shown) attached to the support shaft 17 so as to be fitted to the through hole in a relatively rotatable manner. The boss member is a disk-shaped member having substantially the same dimension in the plate thickness direction as the temple ring 16, and is formed in a shape in which the plate thickness direction of the externally fitted temple ring 16 is inclined with respect to the axial direction of the support shaft 17. Therefore, each side stay 16 is supported by the support shaft 17 via the boss member, and the end surface thereof is inclined with respect to the direction orthogonal to the axis of the support shaft 17, specifically, with an angle substantially equal to the angle formed by the inclined surface of the housing portion 18 with respect to the direction orthogonal to the axis of the housing portion 18.

The pair of housing portions 18 and 18 are attached to the support shaft 17 so as to be relatively non-rotatable with respect to the support shaft 17 in a state where the support shaft 17 is inserted through the through-holes 18a, on both sides of the plurality of temple rings 16 provided on the support shaft 17 in this manner. However, this mounting is performed in a state where the inclined surface of each housing portion 18 faces the temple ring 16. In each of the bayonet ring type temples 15, each of the housing portions 18 is supported by the support shaft 17 so that the inclined surface abuts on the adjacent temple ring 16. In the bayonet temple 13, each of the bayonet ring type temples 15 is assembled to the inner rod 14 such that the axial center of the support shaft 17 coincides with the axial center of the inner rod 14.

In the above-described ratchet temple 13, each of the ratchet ring type temples 15 has a protruding portion 19 protruding from the other end surface (the end surface opposite to the inclined surface) of the housing portion 18 on the end portion side (the side opposite to the inner lever 14) in the axial direction. The protruding portion 19 is in the form of a small-diameter shaft smaller than the case portion 18, and protrudes from the other end surface at a position where the axial center thereof coincides with the axial center of the case portion 18. The protruding portion 19 is formed integrally with the housing portion 18. The stab-ring temples 13 are supported by the base body 10 at the protruding portions 19 of the respective stab-ring temples 15. Therefore, the protruding portion 19 of each of the barbed loop type temple 15 becomes a shaft portion of the barbed temple 13 for bringing the barbed temple 13 into a state of being supported by the base body 10.

The full-width temple device 2 including the above components is configured as follows: the cover 11 is attached to the attached portion 10a1 of the bottom plate 10a at the attaching portion 11a in a state where the position in the width direction is made uniform and the inner side surface of the curved surface in the base-side guide portion 10a2 of the bottom plate 10a is opposed to the inner side surface of the curved portion in the cover-side guide portion 11b of the cover 11. In this attachment, the engaged portion 11c of the cover 11 and the engaging portion 10a3 of the base plate 10a are engaged with each other.

The mounting is performed using a screw member 40. Then, a through hole 11f through which the screw member 40 is inserted is formed in the mounting portion 11a of the cover 11 so as to penetrate in the plate thickness direction. On the other hand, the attached portion 10a1 of the bottom plate 10a has a female screw hole 10a5 into which the screw member 40 is screwed, formed so as to face the through hole 11f of the attachment portion 11 a.

In addition, according to this attachment, the space 12 for accommodating the stab-bar temple 13 is defined by the pedestal-side guide portion 10a2 in the bottom plate 10a, the cover-side guide portion 11b and the engaged portion 11c in the cover 11. However, in this attached state, the front end of the chassis-side guide portion 10a2 is separated from the front end of the cover-side guide portion 11b, and a part of the space 12 is open to the outside on the side of the front end. The size of the open portion (the distance between the tip of the pedestal-side guide portion 10a2 and the tip of the hood-side guide portion 11 b) is smaller than the diameter of the inner rod 14 of the stab-bar temple 13, and the stab-bar temple 13 does not come out of the open portion.

The stab-bar temple 13 is accommodated in the space 12 defined as described above. The full temple device 2 configured as described above is attached to the bracket 4 as described above to the attached portion 10a1 of the bottom plate 10a in a state where the portion where the space 12 is open faces the cloth fell CF side as described above. Thus, the full-width temple device 2 is provided on the loom 1 in a manner supported by the front upper stay 8. The attached portion 10a1 of the bottom plate 10a is attached to the bracket 4 using the screw member 41. Then, a through hole 10a6 through which the screw member 41 is inserted is formed in the attached portion 10a1 of the bottom plate 10a so as to penetrate in the plate thickness direction. On the other hand, in the bracket 4, a female screw hole 4a into which the screw member 41 is screwed is formed so as to face the through hole 10a6 of the attached portion 10a 1.

Incidentally, in the loom 1, the woven cloth W is introduced into the space 12 from the weaving shed CF via the aforementioned tip end of the pedestal-side guide portion 10a2 in the full temple device 2, and is wound around the stab-beam temple 13 in the space 12. Further, in the full temple device 2, the woven cloth W turns toward the front end side of the cover-side guide portion 11b in the space 12 and is guided along the upper surface of the cover-side guide portion 11b via the front end of the cover-side guide portion 11 b.

Thus, in the full temple device 2, the stab-bar temple 13 is biased toward the open portion (the tip of the chassis-side guide portion 10a2 and the cover-side guide portion 11 b) in the space 12 by the tension of the wound fabric W. As a result, the woven cloth W is held (sandwiched) by the inner bar 14, the bottom plate 10a, and the cover 11 in the range of the inner bar 14 in the stab-bar temple 13. In the range of each of the loop temple 15, the woven fabric W is held by the needles 16a of each of the temple rings 16. Therefore, the woven cloth W is held over the entire width thereof by the barbed temple 13, the bottom plate 10a, and the cover 11.

In the full temple device 2 described above, in the present invention, the stab-ring temple 13 is configured such that the outer diameter of the portion of the each stab-ring temple 15 where the fabric W is wound on the housing portion 18 on the inner bar 14 side and the housing portion 18 on the end portion side is substantially the same as the outer diameter of the inner bar 14. In the end-side housing 18, the portion of the end-side housing 18 over which the fabric W is wound does not necessarily have to be the entire axial direction thereof (portion) due to the relation with the weaving width of the fabric W. In the case 18 on the end portion side, at least the portion where the woven cloth W is wound has substantially the same diameter as described above.

In the present embodiment, as shown in fig. 3, the housing portion 18 on the end portion side is formed so that the outer diameter is the same in the axial direction. The outer diameter of the case portion 18 on the end portion side is the same as the outer diameter of the case portion 18 on the inner lever 14 side and is substantially the same as the outer diameter of the inner lever 14.

In the full temple device 2 including the above-described stab-bar temple 13, the base body 10 has support portions at both ends thereof for supporting the stab-bar temple 13 at the shaft portion 19 thereof. The full-width temple device 2 further includes an attachment member that is detachably attached to the support portion and includes a plate-shaped shaft fixing portion having an engaging portion formed to engage with the circumferential surface of the shaft portion 19 of the stab-bar temple 13. Hereinafter, an embodiment (this embodiment) of the full temple device 2 will be described in detail with reference to fig. 4 to 7.

In the full temple device 2, the base body 10 has a support portion 10b for bringing the stab-bar temple 13 into a state of being supported by the bottom plate 10 a. The support portion 10b is a plate-like member, and has a rectangular shape as viewed in the plate thickness direction. The support portion 10b has a through hole 10b1 through which the screw member 21 for attaching the support portion 10b to the bottom plate 10a is inserted, at a portion (one end portion) on one end side in the longitudinal direction of the end surface. Two through holes 10b1 are formed at an interval in the lateral direction of the end face of the support portion 10 b.

In the base 10, the support portions 10b are attached to the bottom plate 10a on both sides of the bottom plate 10a in the width direction. More specifically, two female screw holes (not shown) that are open on both side surfaces in the longitudinal direction are formed in the attached portion 10a1 of the bottom plate 10a at the same interval as the interval between the two through holes 10b1 and 10b1 in the support portion 10 b. Each support portion 10b is attached to the bottom plate 10a by screwing the screw member 21 inserted through each through hole 10b1 to the female screw hole in the bottom plate 10 a.

The mounting is performed in a direction in which a portion (the other end portion) on the other end side in the longitudinal direction of the supporting portion 10b is located on the engagement portion 10a3 side with respect to the mounted portion 10a1 in the plate thickness direction of the mounted portion 10a 1. Therefore, in this attached state, the supporting portions 10b are set in a state of being erected from the attached portion 10a1 of the bottom plate 10a toward the engaging portion 10a3 side in the base 10.

The dimension in the longitudinal direction of each support portion 10b is larger than the dimension in the plate thickness direction of the assembly of the cover 11 and the bottom plate 10a in the state where the cover 11 is attached to the bottom plate 10a and the two are combined as described above (the dimension from the end face of the bottom plate 10a (attached portion 10a1) attached to the bracket 4 to the upper surface of the cover-side guide portion 11b of the cover 11). Therefore, in a state where the cover 11 is attached to the base 10 including the support portions 10b, the other end portion of each support portion 10b is located at a position not overlapping with the cover 11 as viewed in the width direction.

The full-width temple device 2 includes the attachment member 30, and the attachment member 30 is provided for each support portion 10b of the base body 10 so that the stab-bar temple 13 is supported on the base body 10 configured as described above. Each of the mounting members 30 is a plate-like member, and has a substantially rectangular shape when viewed in the plate thickness direction. The dimension of the end face of each mounting member 30 in the short-side direction substantially coincides with the dimension of the support portion 10b in the long-side direction. The dimension of the end face of each mounting member 30 in the longitudinal direction substantially matches the dimensions of the base plate 10a and the cover 11 in the front-rear direction.

Each of the mounting members 30 is provided to be detachably mounted on the corresponding support portion 10 b. Then, a through hole 10b2 through which the screw member 22 for attaching the attachment member 30 to the support portion 10b is inserted is formed in each support portion 10 b. Two through holes 10b2 are formed in the other end portion of the support portion 10b with a space therebetween in the lateral direction of the support portion 10 b. On the other hand, in each mounting member 30, two female screw holes 31, 31 are formed at the same interval as the interval between the two through holes 10b2, 10b2 in the other end portion of the support portion 10 b. The two female screw holes 31, 31 of each mounting member 30 are positioned as follows: when the attachment member 30 is attached to the support portion 10b of the base 10, the attachment member 30 is in a state of overlapping the space 12 in the assembly as viewed in the width direction.

Each mounting member 30 is mounted to the corresponding support portion 10b by screwing the screw member 22 inserted through each through hole 10b2 at the other end portion of the support portion 10b into the female screw hole 31. Wherein the mounting is performed in the following manner: in the width direction, the screw member 22 is inserted from the inner side of the base 10 with respect to the support portion 10b to the through hole 10b2 of the support portion 10b in a state where the mounting member 30 faces the outer end face of each support portion 10b in the base 10.

The mounting is performed in a direction in which the mounting member 30 is overlapped with the space 12 in the assembly when viewed in the width direction. In this attached state, the screw member 21 that fixes the support portion 10b to the attached portion 10a1 and each of the attachment members 30 overlap each other when viewed in the width direction. Then, in order to allow the head portion of the screw member 21 to be disposed between the mounting member 30 and the support portion 10b, a recess is formed in the base 10 at the outer end surface of each support portion 10b, the portion of the base against which the head portion of the screw member 21 abuts being recessed with respect to portions other than the portion.

The diameter of each through hole 10b2 at the other end of each support portion 10b is slightly larger than the diameter of the screw member 22 inserted into the through hole 10b 2. Thus, in the full-width temple device 2, the mounting position of the mounting member 30 to the support portion 10b can be adjusted.

Each of the mounting members 30 has an engaging portion 32 that engages with the circumferential surface of the shaft portion 19 of the stab-bar temple 13 in order to support the stab-bar temple 13 in the state of being mounted on the support portion 10b as described above. In the present embodiment, the plate-like mounting members 30 having the engaging portions 32 correspond to the shaft fixing portions as a whole. In the present embodiment, the engaging portion 32 of each mounting member 30 is an engaging hole formed to penetrate through the mounting member 30 in the plate thickness direction.

The diameter of the engaging hole 32 in each mounting member 30 is substantially equal to the diameter of the shaft portion 19 in the stab-shank temple 13. Therefore, the barbed temple 13 is supported by the two mounting members 30 and 30 so that the shaft portions 19 thereof are fitted into the engagement holes 32 of the mounting members 30. The positions of the engagement holes 32 in the mounting members 30 are as follows: in a state where the attachment member 30 is attached to the support portion 10b, the above-described gripping (pinching) of the fabric W is achieved in the range of the inner bar 14 in the stab-bar temple 13 in the state supported as described above. In addition, each of the mounting members 30 is mounted to the support portion 10b in a state where the stab-bar temple 13 is supported as described above, so that the stab-bar temple 13 is supported by the base body 10.

Further, in the present embodiment, a part of the circumferential surface of each shaft portion 19 in the stab temple 13 is formed in a planar shape. That is, each shaft portion 19 has a flat surface portion 19a on its peripheral surface. In contrast, each of the engagement holes 32 is formed such that a part of the inner peripheral surface thereof is a flat surface having substantially the same size as the flat surface portion 19a of the peripheral surface of the shaft portion 19 so that the inner peripheral surface thereof also abuts against the flat surface portion 19a of the shaft portion 19. That is, each engagement hole 32 has a planar abutment surface 32a on its inner peripheral surface, which abuts the planar portion 19a of the shaft portion 19. In this way, each engagement hole 32 is formed in a hole shape that fits into the shaft portion 19 in a state of abutting (engaging) over the entire circumference of the inner circumferential surface thereof.

By forming the shaft portions 19 and the engagement holes 32 as described above, the angle of the barbed temple 13 about the axis corresponds to the direction of the abutment surface 32a in the engagement hole 32 of the mounting member 30 in the state where the barbed temple 13 is supported by the base 10 as described above. The direction of the contact surface 32a described herein corresponds to an angle formed by the contact surface 32a and the longitudinal direction (the short-side direction) when the mounting member 30 is viewed in the plate thickness direction. The direction of the abutment surface 32a is set in accordance with the direction of the axis of the planar portion 19a of each shaft portion 19 of the stab-bar temple 13 and the fabric W to be woven (a desired tensile force with respect to the fabric W).

In addition, in a state where the stab-ring temple 13 is supported by the base body 10 as described above, each of the stab-ring temples 15 is also in a state of being close to the bottom plate 10a and the cover 11. The bayonet temple 13 is configured such that, when viewed in the axial direction, the needle 16a of each temple ring 16 of the bayonet-ring temple 15 protrudes from the outer peripheral surface of the inner stem 14. In the full-width temple device 2, in order to avoid interference between the needle 16a of each temple ring 16 of each loop temple 15 and the base plate 10a and the cover 11, a recess is formed in the base plate 10a and the cover 11 at a portion facing each loop temple 15.

Specifically, the curved inner surface of the base-side guide portion 10a2 of the bottom plate 10a is formed with a base-side concave portion 10a4 that is concave over the range of the plurality of temple rings 16 in the axial direction of each grommet-type temple 15. Further, a cover-side concave portion 11e that is concave over the same range as the range in the width direction of the base-side concave portion 10a4 in the bottom plate 10a is formed on the inner side surface of the curved portion in the cover-side guide portion 11b of the cover 11 and the surface (surface continuous with the inner side surface of the cover-side guide portion 11 b) in the engaged portion 11 c. Thus, in the full-width temple device 2, in a state where the temple bar 13 is supported by the base body 10 as described above, the needle 16a of each temple ring 16 of the temple bar 13 does not interfere with the base plate 10a and the cover 11.

The stab-pin temple 13 is fixed to each of the mounting members 30 in a state of being supported by the base body 10 as described above. In the present embodiment, an open fastening structure is used as a fixing mechanism for this purpose.

With respect to this opening fastening structure, the opening fastening structure 33 is configured to include: a slit 34 formed in the mounting member 30 so as to communicate with the engagement hole 32; and a screw member 37 screwed to the mounting member 30 in such a manner as to cross the slit 34.

More specifically, the slit 34 is formed to penetrate through each of the mounting members 30 in the plate thickness direction thereof and to extend from the engagement hole 32 in the longitudinal direction of the mounting member 30. The position of the engagement hole 32 communicating with the slit 34 is a position on the opposite side of the portion of the mounting member 30 in the longitudinal direction from the center of the engagement hole 32 where the space 12 is open, and near the center of the engagement hole 32 in the short-side direction of the mounting member 30 when the full temple device 2 is viewed in the width direction. The position of the inner peripheral surface of the engagement hole 32 where the slit 34 communicates (opens) is different from the position where the contact surface 32a is formed, and in the illustrated example, the position is a position facing the contact surface 32 a. In the illustrated example, each mounting member 30 is formed with a through hole penetrating in the plate thickness direction so as to communicate with the slit 34 on the opposite side of the slit 34 from the side communicating with the engagement hole 32. The aperture of the through hole through which the slit 34 communicates is larger than the distance between the two facing surfaces 34a and 34b of the slit 34.

As described above, the screw member 37 is screwed to each mounting member 30 so as to cross the slit 34. That is, the screw member 37 is inserted into the attachment member 30 so that the axis thereof coincides with the short side direction of the attachment member 30 within the range of the slit 34 in the long side direction of the attachment member 30.

Then, in the mounting member 30, a through hole 35 that penetrates in the short direction and opens to one of the two opposing surfaces 34a and 34b of the slit 34 is formed in a portion on one side of the slit 34 in the short direction. On the other hand, in the other side portion of the mounting member 30 with respect to the slit 34 in the short side direction, a female screw hole 36 is formed which penetrates the other side portion in the short side direction, opens to the other facing surface 34b, and faces the through hole 35 via the slit 34. In the illustrated example, the portion forming the one side of the through hole 35 is a portion located above the slit 34 in a state where the full temple device 2 is installed in the loom 1.

In the full-width temple device 2 in which the opening fastening structure 33 is provided in the mounting member 30, the threaded member 37 inserted into the through hole 35 of the mounting member 30 is screwed into the female screw hole 36 through the slit 34, and the threaded member 37 is fastened, whereby the shaft portion 19 fitted into the engagement hole 32 communicating with the slit 34 is fastened. Thereby, the stab-pole temple 13 is fixed to the mounting member 30.

Further, each of the mounting members 30 is provided on the full temple device 2 by being attached to the support portion 10b as described above, but in the present embodiment, the distance in the width direction between the two mounting members 30, 30 substantially coincides with the dimension in the width direction of the bottom plate 10a (the pedestal-side guide portion 10a 2).

More specifically, recesses are formed in the bottom plate 10a at both sides in the width direction and in the portions where the support portions 10b are attached, the recesses being recessed by an amount corresponding to the thickness of the support portions 10 b. Thus, in the state where the support portion 10b is attached to the bottom plate 10a, the position of the outer end surface of the support portion 10b in the width direction substantially coincides with the position of the outermost portion of the two side surfaces of the bottom plate 10 a. Further, recesses allowing the arrangement of the support portions 10b attached to the bottom plate 10a in this manner are formed on both sides of the cover 11 in the width direction. Thus, the position of the outer end surface of the support portion 10b in the attached state is substantially matched with the position of the outermost portion of the both side surfaces of the cover 11 in the width direction.

In the full-width temple device 2, the mounting members 30 are mounted to the support portion 10b mounted to the base plate 10a in the above-described manner, and the positions of the inner end surfaces (the side of the support portion 10 b) thereof in the width direction are aligned with the positions of the outer end surfaces of the support portion 10 b. Therefore, the distance between the two mounting members 30, 30 in the width direction substantially matches the dimension of the bottom plate 10a (the dimension between the outermost portions of the two side surfaces).

In the bayonet temple 13, as described above, the diameter of the shaft portion 19 of each bayonet ring type temple 15 is smaller than that of the housing portion 18, and therefore, an outer end surface (a surface outside the range where the shaft portion 19 exists in the other end surface) which is a surface facing the outside in the axial direction of the housing portion 18 is provided between the shaft portion 19 and the housing portion 18 on the end portion side (the side opposite to the inner lever 14 side). In the present embodiment, the barbed temple 13 is: the distance between the two outer end surfaces in the axial direction substantially coincides with the dimension of the bottom plate 10a in the width direction, that is, the distance between the two mounting members 30, 30 in the width direction.

Therefore, the stab leg temple 13 is in a state in which the outer end surface thereof abuts against the inner end surface of each mounting member 30 in the base body 10 in a state in which it is supported by the base body 10 as described above. Thus, the position of the stab-beam temple 13 in the width direction is restricted by the two mounting members 30, 30 in the state of being supported in this manner.

In the bayonet temple 13, as described above, each of the bayonet ring type temples 15 is assembled to the inner rod 14 such that the axial center of the support shaft 17 coincides with the axial center of the inner rod 14. In the present embodiment, the bayonet temple 13 is structured such that each of the bayonet ring type temples 15 is detachable from the inner rod 14.

More specifically, each of the barbed temple 15 is configured as described above: a pair of housing portions 18, 18 are mounted to the support shaft 17 in a manner sandwiching the plurality of temple rings 16 therebetween. The length of the support shaft 17 is larger than the length from the end surface of the shaft portion 19 of the grommet-type temple 15 to the other end surface (the end surface opposite to the inclined surface) of the case portion 18 on the inner lever 14 side (the side opposite to the shaft portion 19). The housing 18 on the end portion side (shaft portion 19 side) is attached to the support shaft 17 in a state where the position of the end surface of the shaft portion 19 substantially matches the position of one end surface of the support shaft 17. Therefore, in each of the barbed loop type temples 15, the other end portion (the other end portion) of the support shaft 17 protrudes from the housing portion 18 on the inner lever 14 side.

On the other hand, the inner rod 14 is formed with insertion holes 14a, which are capable of inserting the hole diameters of the support shafts 17 in the barbed temple 15, so as to be open at the respective end surfaces at both ends thereof. When the inside lever 14 is viewed in the axial direction, the center of each insertion hole 14a is formed to substantially coincide with the axial center of the inside lever 14. The depth dimension of the insertion hole 14a is larger than the amount of projection of the support shaft 17 from the case portion 18 on the inner lever 14 side in the stab-ring temple 15 as described above.

In the stab-ring temple 13, the other end portion of the support shaft 17 in each stab-ring temple 15 is inserted into the insertion hole 14a in the inner rod 14, and each stab-ring temple 15 is assembled to the inner rod 14, so that the axis of the support shaft 17 in each stab-ring temple 15 and the axis of the inner rod 14 are aligned as described above.

The hole diameter of the insertion hole 14a in the inner rod 14 is set to a size such that the support shaft 17 is fitted into the inner rod 14 with a gap therebetween in a state where the other end portion of the support shaft 17 is inserted. The bayonet ring type temple 15 is assembled to the inner rod 14 only by inserting (fitting with a clearance) the support shaft 17 into the insertion hole 14 a. Therefore, the bayonet temple 13 is structured such that each of the bayonet ring type temples 15 is detachable from the inner rod 14. In the bayonet temple 13, the inner lever 14 and the bayonet ring temple 15 (support shaft 17) are rotatable relative to each other in the assembled state.

In the full temple device 2 configured as described above, in the present embodiment, the cover 11 is configured such that a portion corresponding to each of the loop temple 15 and portions other than the portion can be divided in the width direction (the direction that coincides with the weaving width direction in a state where the full temple device 2 is installed on the loom 1). More specifically, in the cover 11, a portion of each end portion corresponding to the barbed temple 15 in the width direction and a portion between both end portions thereof are formed as different members, respectively. That is, the cover 11 is composed of two members (end-side members) forming respective end portions thereof and a member (center member) forming a portion between the two end-side members.

In the cover 11 configured as described above, the dimension of each end-side member in the width direction is larger than the dimension of the grommet-type temple 15 in the axial direction. Therefore, in the full-width temple device 2, the boundary position of each of the end-side members in the cover 11 with respect to the center member is located inward of the positions of both ends of the inside bar 14 in the axial direction of the stab-bar temple 13. The cover 11 is configured such that each of the end members and the center member is attached to the bottom plate 10a of the base 10. Thus, the cover 11 is configured to be dividable between the end members and the central member.

The bottom plate 10a of the base body 10 is configured to be dividable into a yarn feeding side portion and a yarn feeding side portion in the presence range of the inner bar 14 of the stab-bar temple 13 in the width direction (the direction that coincides with the weaving width direction in a state where the full-width temple device 2 is installed on the loom 1). That is, the base plate 10a is composed of a member (yarn-feeding-side member) serving as a yarn-feeding-side portion and a member (yarn-feeding-side member) serving as a yarn-feeding-side portion. In the present embodiment, the yarn-feeding-reverse-side member and the yarn-feeding-side member are dimensioned such that the boundary position thereof in the width direction substantially coincides with the boundary between the end-side member and the center member on the opposite side of the yarn feeding in the cover 11. The base plate 10a is configured such that the yarn-feeding-side member and the yarn-feeding-side member are attached to the bracket 4, respectively. Thus, the bottom plate 10a is configured to be dividable between the yarn-feeding-side member and the yarn-feeding-side member.

Further, according to the above-described barbed temple 13, in the full temple device 2 described above, the woven fabric W is parallel to the axis of each barbed temple 15 in a state where the woven fabric W is wound around the barbed temple 13 as described above. Thus, the woven cloth W is sufficiently pierced by the needles 16a of all the temple rings 16 in a state where the range of each loop-type temple 15 is gripped by the needles 16a of each temple ring 16 as described above. As a result, the gripping of the fabric W by the loop temple 15 is performed with a desired gripping force. Therefore, according to the stab-bar temple 13 of the present embodiment, the fabric W can be sufficiently gripped.

In the above-described example, the bayonet temple 13 is structured such that each of the bayonet ring type temples 15 is detachable from the inner rod 14. However, in the present invention, the bayonet temple is not limited to the structure in which the bayonet ring temple is detachable from the inner rod. For example, the bar temple may be configured by using a shaft penetrating in the axial direction of the bar temple as a support shaft, supporting a housing portion and a temple ring constituting a bar-type temple at both end portions of the support shaft, respectively, and rotatably supporting an inner bar formed in a hollow cylindrical shape between the bar-type temples. With this configuration, the bayonet temple is configured such that the bayonet ring temple is not attachable to and detachable from the inner pole.

The present invention is not limited to the above-described examples, and various modifications can be made without departing from the scope of the present invention.
