- the present invention relates to a roller temple for a loom, the roller temple being capable of preventing weaving crimp of a woven fabric by an action of keeping a weaving width of the woven fabric constant.
- a loom has temples arranged near a cloth fell at positions corresponding to both ends of a woven fabric in a weaving-width direction. Needles protruding from the temples stick into a woven fabric. Accordingly, a woven fabric to be obtained immediately after weaving is prevented from becoming rapidly crimped by beating (weaving crimp of a woven fabric).
- a roller temple is a type of temple.
- the roller temple differs from a ring temple in that the roller temple keeps a weaving width of a woven fabric constant, whereas the ring temple positively increases a weaving width of a woven fabric by making rotation axes of individual rings having needles inclined with respect to an axis of a ring temple body ( DE 2108778 A1 and JP 082 60 301 A1 relate to the design and a manufacturing method of ring temple bodies). That is, the roller temple merely applies a reaction force of a weaving crimp force to a woven fabric, but does not apply an excessive force to the woven fabric. Hence, the woven fabric can be prevented from being damaged, for example, with a needle-sticking defect.
- roller type see Claim 4 in Claims of Japanese Unexamined Patent Application Publication No. 58-220850 , a further roller temple design is also known from CH 84 434 A ).
- a typical roller temple is configured such that an outer circumferential surface of a temple body, which is a long shaft-like member extending in a weaving-width direction, is processed by scraping to make a plurality of needles sticking into the temple body at intervals in a circumferential direction and an axial direction of the temple body; and shaft portions at both sides of the temple body are rotatably supported with supporting members.
- the method includes boring a plurality of insertion holes in an outer circumferential surface of a cylinder extending in an axial direction at intervals in a circumferential direction and an axial direction of the cylinder; studding (press-fitting) needles into all the insertion holes; and then inserting a shaft into the cylinder.
- a diameter of each insertion hole is small if a diameter of each needle is small, and hence, it is difficult to make an insertion hole in the cylinder by drilling.
- a drill may be damaged (breaking, bending, or the like), resulting in dimensional accuracy and roundness of the insertion hole being degraded.
- a problem in press-fitting may be that the needle is bent at an intermediate portion of the needle. If such defects are found in a part of the cylinder, the entire cylinder is considerable to be a defective product.
- the invention is made in light of the above situations, and it is an object of the invention to facilitate manufacturing of a roller temple, and minimize production of a defective product.
- the invention provides a roller temple for a loom including a temple body having a plurality of needles protruding at intervals in a circumferential direction and an axial direction, thereby providing a needle sticking region extending in a weaving-width direction; a supporting member rotatably supporting the temple body; and a pair of bearings interposed between the temple body and the supporting member and spaced apart from each other in the axial direction.
- the temple body includes a plurality of rings and a shaft member.
- the rings have a plurality of insertion holes arranged at intervals in the circumferential direction, and the plurality of needles protruding from the insertion holes.
- the plurality of rings are adjacently arranged in parallel, and press-fitted onto the shaft member.
- the shaft member is supported by the supporting member with the pair of bearings.
- the needle sticking region is defined by the plurality of rings integrated with the shaft member.
- a configuration may be employed.
- the shaft member may have bearing fitting holes in first and second ends or portions near the first and second ends of the shaft member.
- the supporting member may have a pair of supporting shaft portions to which the bearings are fitted.
- Another configuration may add limitations for the shaft member and the supporting member in the above configuration.
- the shaft member may have a through hole at a center axis thereof in the axial direction, and the bearing fitting holes may be formed in first and second ends or portions near the first and second ends of the through hole.
- the supporting member may include a supporting shaft and supporting bodies. The supporting shaft penetrates through the through hole, and the portions near the first and second ends of the supporting shaft are respectively fitted to the pair of bearings so as to define the pair of supporting shaft portions.
- the supporting bodies have a pair of holding holes for holding first and second ends of the supporting shaft and fixes at least one of the first and second ends of the supporting shaft so as to inhibit the supporting shaft from rotating or moving in the axial direction.
- Still another configuraiton may be employed.
- the supporting member may have a pair of bearing fitting holes.
- first and second ends of the shaft member protruding to the outside of the needle sticking region may be respectively fitted to the pair of bearings.
- a method of manufacturing a temple body includes the step of press-fitting a plurality of rings, which have a plurality of insertion holes arranged at intervals in the circumferential direction and a plurality of needles protruding from the insertion holes, onto a shaft member, thereby integrating the plurality of adjacently arranged rings with the shaft member, to manufacture the temple body having the needle sticking region.
- the method of forming a ring with needles sticking may be a method of inserting needles from an outer circumferential surface of a ring into insertion holes, or a method of inerting needles from an inner circumferential surface of a ring into insertion holes.
- the insertion holes of the ring for the needles are through holes penetrating to the inner circumferential surface, and dimensions are properly determined for a width (lenght in an axial direction) and an inner diameter of a hole, and a length of a needle. Accordingly, the needles can be easily inserted into all the insertion holes from the inner circumferential surface of the ring.
- the needles are inserted into all the insertion holes from the inner circumferential surface, and then, a pressing jig with a predetermined diameter is inserted from an end of the ring into a space surrounded by the inner circumferential surface of the ring.
- the needles are press-fitted into all the inertion holes, and tip portions of the needles can protrude to the outside of the ring.
- the roller temple according to the first aspect of the invention has the temple body including the plurality of rings with the needles sticking, and the shaft member. Also, the plurality of rings press-fitted onto the shaft member define the needle sticking region. Accordingly, as compared with a configuration in which a needle sticking region is defined by a single cylinder, a total length of an individual ring in the weaving-width direction can be markedly reduced. Thus, a defective product is hardly produced in the manufacturing process for boring the insertion holes and inserting the base portions of the needles into the insertion holes, thereby facilitating the manufacuring. If a single ring becomes defective in the manufacturing process until when the needles protrude from the insertion holes, other acceptable product can be used to form the roller temple. Therefore, a single defective ring does not affect the quality of the entire rings for forming the roller temple.
- the plurality of rings with the needles protruding are press-fitted onto the shaft member, so as to be integrated and to form the needle sticking region.
- a ring which is made defective during the manufacturing process until when the needles protrude from the insertion holes can be removed, and only acceptable rings, can be press-fitted onto the shaft member. Therefore, production of a defective product during the manufacturing process until when the needles protrude from the insertion holes can be overcome.

Description
- The present invention relates to a roller temple for a loom, the roller temple being capable of preventing weaving crimp of a woven fabric by an action of keeping a weaving width of the woven fabric constant.
- In many cases, a loom has temples arranged near a cloth fell at positions corresponding to both ends of a woven fabric in a weaving-width direction. Needles protruding from the temples stick into a woven fabric. Accordingly, a woven fabric to be obtained immediately after weaving is prevented from becoming rapidly crimped by beating (weaving crimp of a woven fabric).
- A roller temple is a type of temple. The roller temple differs from a ring temple in that the roller temple keeps a weaving width of a woven fabric constant, whereas the ring temple positively increases a weaving width of a woven fabric by making rotation axes of individual rings having needles inclined with respect to an axis of a ring temple body (
DE 2108778 A1 andJP 082 60 301 A1 Claim 4 in Claims of Japanese Unexamined Patent Application Publication No.58-220850 CH 84 434 A - In particular, a typical roller temple is configured such that an outer circumferential surface of a temple body, which is a long shaft-like member extending in a weaving-width direction, is processed by scraping to make a plurality of needles sticking into the temple body at intervals in a circumferential direction and an axial direction of the temple body; and shaft portions at both sides of the temple body are rotatably supported with supporting members.
- To make needles protrude by scraping, a high-level technique is necessary. Hence, the inventors have attempted to manufacture a roller temple by the following manufacturing method.
- The method includes boring a plurality of insertion holes in an outer circumferential surface of a cylinder extending in an axial direction at intervals in a circumferential direction and an axial direction of the cylinder; studding (press-fitting) needles into all the insertion holes; and then inserting a shaft into the cylinder. Unfortunately, a diameter of each insertion hole is small if a diameter of each needle is small, and hence, it is difficult to make an insertion hole in the cylinder by drilling. A drill may be damaged (breaking, bending, or the like), resulting in dimensional accuracy and roundness of the insertion hole being degraded. Thus, it is difficult to press-fit the needle into the insertion hole, and the needle may easily become detached from the insertion hole after the needle is press-fitted. For example, a problem in press-fitting may be that the needle is bent at an intermediate portion of the needle. If such defects are found in a part of the cylinder, the entire cylinder is considerable to be a defective product.
- The invention is made in light of the above situations, and it is an object of the invention to facilitate manufacturing of a roller temple, and minimize production of a defective product.
- It is presupposed that the invention provides a roller temple for a loom including a temple body having a plurality of needles protruding at intervals in a circumferential direction and an axial direction, thereby providing a needle sticking region extending in a weaving-width direction; a supporting member rotatably supporting the temple body; and a pair of bearings interposed between the temple body and the supporting member and spaced apart from each other in the axial direction.
- According to a first aspect of the invention, the temple body includes a plurality of rings and a shaft member. The rings have a plurality of insertion holes arranged at intervals in the circumferential direction, and the plurality of needles protruding from the insertion holes. The plurality of rings are adjacently arranged in parallel, and press-fitted onto the shaft member. The shaft member is supported by the supporting member with the pair of bearings. The needle sticking region is defined by the plurality of rings integrated with the shaft member.
- To rotatably support the temple body with the supporting member, a configuration may be employed.
- In particular, the shaft member may have bearing fitting holes in first and second ends or portions near the first and second ends of the shaft member. Also, the supporting member may have a pair of supporting shaft portions to which the bearings are fitted.
- Another configuration may add limitations for the shaft member and the supporting member in the above configuration.
- In particular, the shaft member may have a through hole at a center axis thereof in the axial direction, and the bearing fitting holes may be formed in first and second ends or portions near the first and second ends of the through hole. The supporting member may include a supporting shaft and supporting bodies. The supporting shaft penetrates through the through hole, and the portions near the first and second ends of the supporting shaft are respectively fitted to the pair of bearings so as to define the pair of supporting shaft portions. The supporting bodies have a pair of holding holes for holding first and second ends of the supporting shaft and fixes at least one of the first and second ends of the supporting shaft so as to inhibit the supporting shaft from rotating or moving in the axial direction.
- To rotatably support the temple body with the supporting member, still another configuraiton may be employed.
- In particular, the supporting member may have a pair of bearing fitting holes. Also, first and second ends of the shaft member protruding to the outside of the needle sticking region may be respectively fitted to the pair of bearings.
- A method of manufacturing a temple body includes the step of press-fitting a plurality of rings, which have a plurality of insertion holes arranged at intervals in the circumferential direction and a plurality of needles protruding from the insertion holes, onto a shaft member, thereby integrating the plurality of adjacently arranged rings with the shaft member, to manufacture the temple body having the needle sticking region.
- The method of forming a ring with needles sticking may be a method of inserting needles from an outer circumferential surface of a ring into insertion holes, or a method of inerting needles from an inner circumferential surface of a ring into insertion holes. In paricular, the insertion holes of the ring for the needles are through holes penetrating to the inner circumferential surface, and dimensions are properly determined for a width (lenght in an axial direction) and an inner diameter of a hole, and a length of a needle. Accordingly, the needles can be easily inserted into all the insertion holes from the inner circumferential surface of the ring. The needles are inserted into all the insertion holes from the inner circumferential surface, and then, a pressing jig with a predetermined diameter is inserted from an end of the ring into a space surrounded by the inner circumferential surface of the ring. Hence, the needles are press-fitted into all the inertion holes, and tip portions of the needles can protrude to the outside of the ring. With the method of forming the ring with the needles, in which the needles are inserted from the inner circumferential surface of the ring, since base portions of the needles, but not tip portions thereof, are pushed, the thin tip portions are prevented from being damaged. Also, since the thin tip portions advance in the inertion holes, press-fitting can be efficiently performed.
- The roller temple according to the first aspect of the invention has the temple body including the plurality of rings with the needles sticking, and the shaft member. Also, the plurality of rings press-fitted onto the shaft member define the needle sticking region. Accordingly, as compared with a configuration in which a needle sticking region is defined by a single cylinder, a total length of an individual ring in the weaving-width direction can be markedly reduced. Thus, a defective product is hardly produced in the manufacturing process for boring the insertion holes and inserting the base portions of the needles into the insertion holes, thereby facilitating the manufacuring. If a single ring becomes defective in the manufacturing process until when the needles protrude from the insertion holes, other acceptable product can be used to form the roller temple. Therefore, a single defective ring does not affect the quality of the entire rings for forming the roller temple.
- Also, with the method of manufacturing the temple body the plurality of rings with the needles protruding are press-fitted onto the shaft member, so as to be integrated and to form the needle sticking region. Hence, a ring, which is made defective during the manufacturing process until when the needles protrude from the insertion holes can be removed, and only acceptable rings, can be press-fitted onto the shaft member. Therefore, production of a defective product during the manufacturing process until when the needles protrude from the insertion holes can be overcome.

Fig. 1 is a front view with a partially enlarged view showing a roller temple according to a first embodiment; -
Figs. 2A and 2B are work process diagrams showing a work process of press-fitting needles into rings; and -
Fig. 3 is a front view showing a roller temple according to a second embodiment. - Referring to
Fig. 1 , a roller temple 1 is arranged near a cloth fell at a position corresponding to each end of a woven fabric in a weaving-width direction. The roller temple 1 is fixed to a loom frame (not shown). - The roller temple 1 according to a first embodiment includes a
cylindrical temple body 2 extending in the weaving-width direction, a supportingmember 3 that supports first and second ends of thetemple body 2, and twobearings 4 respectively interposed between inner circumferential surfaces of the first and second ends of thetemple body 2 and an outer circumferential surface of the supportingmember 3. - In the
temple body 2, needles 5 protrude from the outer circumferential surface thereof, and a total length of that region with theneedles 5 in the weaving-width direction defines a needle sticking region. Theneedles 5 are configured to stick into a woven fabric while being rotated in accordance with advancement of the woven fabric. Thetemple body 2 includes a plurality ofrings 6 from which theneedles 5 protrude, and ashaft member 7 that allows the plurality ofrings 6 to be press-fitted thereonto while therings 6 are adjacently arranged in parallel in the weaving-width direction. By press-fitting the plurality ofrings 6 onto theshaft member 7, the plurality ofrings 6 and theshaft member 7 can be integrated. That is, the plurality ofrings 6 and theshaft member 7 are inhibited from being relatively rotated or relatively moved in an axial direction. The plurality ofrings 6 arranged in parallel in the weaving-width direction define the needle sticking region. - Each
ring 6 hasinsertion holes 8 for theneedles 5 in an outer circumferential surface thereof at even intervals in the circumferential direction. Theneedles 5 are provided at a plurality of circumferences, or three circumferences in this embodiment, being spaced apart from each other in the axial direction. Phases of the insertion holes 8 provided on the adjacent circumferences are shifted. Accordingly, the insertion holes 8 are provided on the outer circumferential surface of thering 6 in a staggered manner. Eachinsertion hole 8 is bored from the outer circumferential surface of thering 6 toward the center axis, and penetrates through thering 6 to an innercircumferential surface 9 thereof. A base portion of theneedle 5 is press-fitted into theinsertion hole 8, and a tip portion of theneedle 5 protrudes from the outer circumferential surface of thering 6. Accordingly, the plurality ofneedles 5 protrude from the outer circumferential surface of thering 6 in a staggered manner. - The
needle 5 sticks into a woven fabric, and hence, the tip portion of theneedle 5 is thin, and the base portion thereof has a diameter larger than that of theinsertion hole 8. As shown inFig. 2 , when theneedles 5 are to be press-fitted into the insertion holes 8, the tip portions of theneedles 5 are temporarily inserted into all the insertion holes 8 from the innercircumferential surface 9 of thering 6. Theneedles 5 are held with friction so as not to become detached while only the base portions of theneedles 5 protrude from the innercircumferential surface 9. Then, apressing jig 11 having a predetermined diameter and a tip portion thereof being tapered is inserted from an end of thering 6 into a space surrounded by the innercircumferential surface 9 thereof, and is moved along the axial direction. Thepressing jig 11 pushes all theneedles 5 collectively, so as to press-fit theneedles 5 into the insertion holes 8. Accordingly, theneedles 5 are press-fitted into the insertion holes 8 and fixed thereto, and the tip portions of theneedles 5 protrude from the outer circumferential surface of thering 6. - The
shaft member 7 fixes the plurality ofrings 6 so as to be integrated with the plurality ofrings 6. Theshaft member 7 is a pipe-like member having a throughhole 12 penetrating through theshaft member 7 at the center axis in the axial direction. Bearing fitting holes 13 each having a larger diameter than a diameter at an intermediate portion of the throughhole 12 are respectively formed at first and second ends of the throughhole 12. An outer diameter of theshaft member 7 is larger than an inner diameter of therings 6. Therings 6 are fitted onto theshaft member 7 by interference fitting. That is, therings 6 are press-fitted onto theshaft member 7. - A method of manufacturing the
temple body 2 merely performs a process in which theshaft member 7 is inserted into the space surrounded by the innercircumferential surface 9 of thering 6 with theneedles 5 protruding therefrom so as to press-fit theneedles 5, by a number of times corresponding to the number ofrings 6 to be arranged in parallel in the needle sticking region. Accordingly, the plurality ofrings 6 is integrated with theshaft member 7. - Each
bearing 4 is a sliding bearing, which particularly employs contained metal made of metal or resin, and hence thebearing 4 need not be lubricated for a long period. Alternatively, a rolling bearing such as a needle bearing with grease sealed therein may be employed. The pair ofbearings 4 are respectively press-fitted into the bearingfitting holes 13 of theshaft member 7 after the plurality ofrings 6 are press-fitted. - The supporting
member 3 supports thetemple body 2 so as to be rotatable but not movable in the weaving-width direction by way of thebearings 4 located at first and second ends of the supportingmember 3. The supportingmember 3 includes a supportingshaft 15 penetrating through the throughhole 12 of theshaft member 7 and protruding from first and second ends of theshaft member 7, a pair of supportingbodies shaft 15, and abracket 18 integrating the pair of supportingbodies shaft 15 are fitted to thebearings 4. The supportingshaft 15 has a pair of supportingshaft portions 14 at portions near first and second ends thereof. The first and second ends of the supportingshaft 15 are inserted to holdingholes 19 and 21 respectively formed in the supportingbodies shaft 15 in this embodiment, are fixed to the supportingbodies socket set screws 30 or pins which respectively reach the holding holes 19 and 21 provided at the supportingbodies - As described above, the supporting
shaft 15 has the pair of supportingbodies temple body 2 and sandwiching thetemple body 2, so as to inhibit thetemple body 2 from moving in the axial direction. Also, the supportingshaft 15 rotatably supports the first and second ends of thetemple body 2 with the pair ofbearings 4. - One of the pair of supporting
bodies shaft 15, and a diameter of which is gradually decreased toward the center of a woven fabric into a tapered shape, is calledhead piece 16. The other of the pair of supportingbodies shaft 15 is calledend piece 17. - The
bracket 18 integrates thehead piece 16 and theend piece 17 into a unit with bolts. In a case of a bottom-mounted temple in which a woven fabric passes an upper side of atemple body 2, or in a case of a top-mounted temple in which a woven fabric a lower side of thetemple body 2, thebracket 18 is arranged below or above a passing region of a woven fabric. Thebracket 18 is fixed to a loom frame (not shown). - While all the
rings 6 have a uniform number ofneedles 5 with a uniform protruding length from the outer circumferential surfaces of therings 6 in this embodiment, the protruding length and the number ofneedles 5 may be varied in accordance with arrangement positions of theneedles 5 in the weaving-width direction. In particular, as therings 6 are arranged close to the center of the woven fabric, the protruding length of theneedles 5 is decreased, or the number ofneedles 5 is decreased. In an extreme case, aring 6 arranged closest to the center of the woven fabric may lack aneedle 5. Accordingly, a tensile start position with the roller temple 1, that is, the boundary between a low tensile portion near the center and a high tensile portion where theneedles 5 stick into the woven fabric becomes unclear, thereby preventing a weaving defect such as a warp streak from appearing. - While the insertion holes 8 for the
needles 5 are provided in the outer circumferential surface of thering 6 at the plurality of circumferences spaced apart from each other in the axial direction in this embodiment, the insertion holes 8 may be provided only at a single circumference. Also, while the pair of bearingfitting holes 13 are provided at the first and second ends of the throughhole 12 formed in theshaft member 7 in this embodiment, at least one of the pair of bearingfitting holes 13 may be formed at a position spaced apart from an end of the throughhole 12. - While the
temple body 2 has thirtyrings 6, or ten ormore rings 6 in this embodiment, thetemple body 2 need not have the ten or more rings 6. In view of manufacturing, thetemple body 2 may preferably have three ormore rings 6 as a plurality ofrings 6. The length of aring 6 in the axial direction is determined in accordance with the number ofrings 6, thereby obtaining a predetermined needle sticking region. - While the
shaft member 7 has the throughhole 12 at the center axis thereof in this embodiment, it is not limited thereto. For example, theshaft member 7 may be a solid round bar member and have bearingfitting holes 13 at first and second ends thereof. A pair of supportingbodies fitting holes 13 by welding or the like. The shafts are fitted to thebearings 4; functioning as supportingshaft portions 14. Accordingly, the supportingshaft portions 14 are respectively provided at the pair of supportingbodies - As shown in
Fig. 3 , a roller temple 1 according to a second embodiment includes atemple body 2 with first and second ends thereof protruding to the outside of a needle sticking region, a supportingmember 3 having a pair of bearingfitting holes 13 and rotatably supporting the first and second ends of thetemple body 2, and a pair ofbearings 4 interposed between the first and second ends of thetemple body 2 and the supportingmember 3. Thetemple body 2 includes a plurality ofrings 6 havinginsertion holes 8 from which needles 5 protrude, and ashaft member 7 onto which the plurality ofrings 6 are press-fitted, first and second ends of theshaft member 7 respectively being fitted to thebearings 4. The second embodiment differs from the first embodiment in that theshaft member 7 is a solid member having no though hole at the center axis thereof, and thebearings 4 are fitted onto the outer circumferential surface. - The first and second ends of the
shaft member 7 protrude to the outside of the needle sticking region. That is, the plurality ofrings 6 with theneedles 5 protruding from the outer circumferential surfaces of therings 6 are adjacently arranged in parallel in the weaving-width direction, and in the parallel arrangement state, theshaft member 7 is press-fitted into a space surrounded by innercircumferential surfaces 9 of therings 6. Accordingly, theshaft member 7 and the plurality ofrings 6 are integrated to define the needle sticking region, and the first and second ends of theshaft member 7 protrude to the outside of therings 6 arranged in parallel. - The supporting
member 3 includes a pair of supportingbodies head piece 16 and anend piece 17. Thehead piece 16 and theend piece 17 have bearing fitting holes 13. Thebearings 4 are press-fitted into the bearingfitting holes 13, and the supportingmember 3 supports the first and second ends of theshaft member 7 rotatably with thebearings 4. - The invention is not limited to any of the above-described embodiments, and may be modified as desired within the scope of the invention.
