Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/341,873, “Schmitt Seam,” Maguire et al., filed Dec. 21, 2001, the contents of which are incorporated herein by reference in their entirety.
- The field of the invention relates to process belts and more specifically, to process belts used in manufacturing processes, e.g., the manufacture of pressed board or other paper products.
- Generally, process belts are used in the preparation of pulp or materials in sheet or non-woven fabric, such as paper or board, in the Paper or Board Making Industry. Such process belts are typically woven wire fabric formed into continuous or endless belts by brazing or welding. For example, end sections of such process belts are generally brazed or welded together to form a brazed or welded seam between the end sections of the process belt, thereby introducing a local stiffness at the seam.
- However, brazing or welding typically degrades the strength and malleability of the wires adjacent the brazed or welded seam due to elevated temperatures. The degradation can result in premature failure of such process belts at or near the brazed or welded seam, which generally requires the process belt to be removed, repaired and reinstalled on the paper process machine or to be replaced with a new process belt.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, of embodiments of the invention, together with the general description given above and the detailed description of the embodiments given below, serve to explain the principles of the invention wherein:

FIGS. 1-4 show an embodiment of a process belt, generally indicated at 10, for use in a board processing machine or other paper converting machine (FIG. 10 ) to process a board stock or other paper product. Thebelt 10 is referred to as a “process belt” herein, but can be used in processing both paper or board, oriented strand board, pressed board or joists, depending on the desired process. Theprocess belt 10 comprises a body portion, generally indicated at 12, separating afirst end section 14 and asecond end section 16. Thefirst end section 14 and thesecond end section 16 form ends of thebody portion 12. Thebody portion 12 is only partially shown inFIG. 1 . Thefirst end section 14 is operatively coupled to thesecond end section 16 by a seam, generally indicated at 17, such that thebody portion 12, thefirst end section 14 and thesecond end section 16 are substantially continuous with one another and configured to operatively engage the board processing machine or other paper converting machine, as is further described below. Theseam 17 can include at least one elongated resilient coupling filament 24 (FIGS. 2-4 ) to fixedly secure the first andsecond end sections -
FIG. 2 shows theprocess belt 10 and theseam 17 in greater detail. As illustrated, thebody portion 12 comprises a first plurality of elongatedresilient filaments 20 oriented in a vertical (or first) direction. The vertical direction can be referred to as a machine direction and each elongatedresilient filament 20 can be referred to as a warp filament, for example. Thebody portion 12 can also include a second plurality of elongatedresilient filaments 22 oriented in a horizontal direction (a second direction) transverse to the vertical (or first) direction. The horizontal direction can be referred to as a cross machine direction and each elongatedresilient filament 22 can be referred to as a shute or weft filament, for example. - The
individual filaments body portion 12. Alternatively, a single beam loom or a double beam loom can be used depending on the type of weave pattern chosen for thebelt 10. In the particular weave pattern of theseam 17 shown inFIG. 3 , for example, each vertically extendingfilament 20 can be woven around each horizontally extendingfilament 22. - A first plurality of looped
segments 26 can be attached to thefirst end section 14 of theprocess belt 10, for example, by weaving, bonding or welding. For example, each loopedsegment 26 can include afirst end 28, a second end 30 (FIG. 3 ) and a loopedsection 32 extending between the first andsecond ends section 32 can be configured to form a coupling filament receiving opening 33 therein (FIG. 3 ) configured to receive thecoupling filament 24 therethrough. The first andsecond ends first end section 14 of theprocess belt 10, for example, by weaving (FIG. 3 ) or bonding, such as welding or fusing, so that the loopedsection 32 and the coupling filament receiving opening 33 outwardly extend away from thefirst end section 14. The weaving can be performed manually or mechanically. - Similarly, a second plurality of looped
segments 34 are attached to thesecond end section 16 of theprocess belt 10, for example, by weaving or bonding such as welding or fusing. For example, each loopedsegment 34 can include afirst end 36, a second end 38 (FIG. 3 ) and a loopedsection 40 extending between the first andsecond ends section 40 forms a coupling element receiving opening 41 therein (shown in substantial alignment with the couplingelement receiving opening 33 shown inFIG. 3 ). The first andsecond ends second end section 16 of theprocess belt 10, for example, by weaving (FIG. 3 ) or bonding such as welding or fusing, so that the loopedsection 40 outwardly extends away from thesecond end section 16. - During manual weaving of the looped
segments segments segments respective end portions belt 10. - To effect weaving of the looped
segments respective end sections belt 10, holes may need to be formed in the existingbelt 10. Such holes, which may be formed with a drill, an awl, a plasma arc cutter or other tool capable of forming a hole in thebelt 10, can allowends ends segment belt 10, as described above, about the horizontally extendingfilaments 22. Such holes may also be formed by displacing thefilaments belt 10 in any manner. - Alternatively, in another embodiment, one or both of the first and
second ends segment 26 can be bonded, for example, by welding or fusing, to either the vertically extendingfilaments 20 or the horizontally extendingfilaments 22. Also, thefirst end 28 can be bonded or fused to thesecond end 30 after the loopedportion 32 has been formed. The first andsecond ends segment 32 can also be bonded or fused to the vertically extendingfilaments 20, to the horizontally extendingfilaments 22 or to one another. - Each individual vertically extending
filament 20, each horizontally extendingfilament 22 and the at least one elongatedresilient coupling filament 24 can be made from carbon steel, stainless steel or other sufficiently hardened material, for example, into solid filaments as shown inFIG. 4 . Thefilaments individual filament Filaments belt 10. Combinations of solid and braided or twisted filaments can also be used for thefilaments - Each
filament -
FIGS. 2-4 show the loopedsegments sections resilient coupling filament 24 can be received through theopenings 33, 41 (FIG. 3 ). End portions (not shown) of eachcoupling filament 24 can be bent in a cross machine direction (opposite to the side of thebelt 10, which engages rollers during operation) to help axially position thecoupling filament 24 in the horizontal or cross machine direction. - The looped
segments filaments sections segments belt 10 or bonded or fused to one another. - Alternatively, as shown in
FIG. 5 , aprocess belt 110 can have aseam 117 formed into a castellated configuration. For example, thebelt 110 includes a plurality of thebody portions 12, as described above. Eachbody portion 12 has a first set of the elongated resilient filaments (not shown) oriented in a vertical (or first) direction located in amiddle portion 121 andrespective edge portions body portion 12 also has a second set of the elongated resilient filaments (not shown) oriented in a horizontal (or second) direction. The vertically and horizontally extending filaments can be substantially similar in construction and operation as thefilaments -
Adjacent body portions 12 can be operatively connected to one another by theseam 117 to form acontinuous belt 110. Theseam 117 is substantially similar in configuration and operation as theseam 17, and includes the loopedsegments edge portions adjacent body portions 12 together at the same plane as themiddle portion 121, theseam 117 can be referred to as castellated. - In this embodiment, one or more (e.g., three)
coupling filaments 24 can be provided to cooperate with the loopedsegments middle portion 121 of onebody portion 12 can be operatively connected to a corresponding middle portion of anotherbody portion 12 and eachedge portion body portion 12 can be operatively connected to correspondingedge portions other body portion 12. In this regard, themiddle portion 121 andedge portions body portion 12 substantially act as afirst end section 14 and themiddle portion 121 andedge portions adjacent body portion 12 substantially act as asecond end section 16. - The
middle portion 121 or theedge portions individual filaments edge portion belt 110 and about 6-18 inches in length in the machine direction of thebelt 110. Other numbers of filaments and configurations are possible for eachportion different body portions 12. - Although
FIG. 5 shows threecastellated seams 117, more orless seams 117 can be used in thebelt 110. Thecastellated seam 117 allows for independent replacement of aparticular body portion 12, without having to replace theentire belt 110. Thecastellated seam 117 also can reduce localized stress of thebelt 110 during a board processing machine or other paper converting machine operation, which can increase the life of thebelt 110. For example, if onebody portion 12 becomes worn or damaged after repeated use, thebody portion 12 could be replaced without having to replace theentire belt 110. - The
seam 117 can be used to replace theseam 17 shown inFIG. 1 . Thecastellated seam 117 allows for independent replacement of a particular portion of theseam 117, without having to replace the entire seam. For example, if oneedge portion edge portion middle portion 121 and the other edge portion unrepaired/unreplaced. - In either
seam coupling filament 24 can form a continuous seam between theend sections belt coupling filament 24 can be used to form the continuous seam between theend sections -
Seams segments more coupling filaments 24.FIGS. 6-9 illustrate alternative ways of attaching first and second ends 28, 30 and 34, 36 of loopedsegments respective end section - For example,
FIG. 6 shows a portion of aseam 217, which is variation of theseam 17, attached to oneend section 14 of aprocess belt 210. Thebelt 210 is of the woven type with a plurality of vertically extendingfilaments 220 woven about a plurality of horizontally extendingfilaments 222. Different weave patterns or alternative configurations of thebelt 210 could also be used. - Although the
seam 217 includes loopedsegments 226, 232, only loopedsegment 226 is shown inFIG. 6 . Since loopedsegments 226, 232 are substantially similar in construction and operation to loopedsegments segment 226 will suffice for looped segment 232. - One
end 228 of the loopedsegment 226 is attached to theend section 14 of thebelt 210, at a first horizontally extendingfilament 222. Theopposite end 230 of the loopedsegment 226 is attached to theend section 14 of thebelt 210, at a different horizontally extendingfilament 222 as theend 228. By attaching theends filaments 222, stress can be distributed and strain can be reduced on theseam 217 and thebelt 210. To further distribute stress and reduce strain, adjacent loopedsegments 226 can haverespective ends 230 attached to different horizontally extendingfilaments 222. In this manner, adjacent ends 230 of the loopedsegments 226 are staggered so that everyother end 230 is attached to the same horizontally extendingfilament 222. - Alternatively, adjacent groups of looped
segments 226 can haverespective ends 230 contacted with different horizontally extendingfilaments 222, with looped segments of each group having anend 230 contacted with the same horizontally extendingfilament 222. - In this embodiment, ends 228, 230 can be attached to one or more horizontally extending
filaments 222 by weaving one or both of theends filaments 222 or by bonding, such as welding or fusing, to one or more horizontally extendingfilaments 222. Alternatively, theends adjacent filaments ends belt 210, but rather the attachment of theends belt 210 can be effected by the engagement of theends filaments ends belt 210, thefilaments 220, thefilaments 222 or to one another. -
FIGS. 7-8 show aseam 317, which is variation of theseam 17, which operatively couplesend sections 314, 316 of aprocess belt 310. Thebelt 310 is of the woven type with a plurality of vertically extendingfilaments 320 woven about a plurality of horizontally extendingfilaments 322. Different weave patterns or alternative configurations of thebelt 310 could also be used. -
FIG. 8 shows loopedsegments seam 317 in greater detail, but only a portion of the loopedsegment 326 is shown. Since loopedsegments segments segment 332 will suffice for loopedsegment 326. - Each looped
segment 332 has ends thereof bonded, fused or connected together so that each loopedsegment 332 substantially forms a ∞ shape. Each loopedsegment 332 includes anend portion 334, a connectingportion 335 that connects one end of theend portion 334 to one end of anopposite end portion 336 and a connectingportion 337 that connects another one end of theend portion 336 to the other end of theend portion 334. - In this embodiment, the
end portion 334 is formed to have a generally arcuate configuration to receive acoupling filament 24 therethrough. Theend portion 334 receives acoupling filament 24 in a similar manner as described above with respect to couplingfilament receiving opening 41, for example. The connectingportion 335 extends from theend portion 334 over a plurality of horizontally extendingfilaments 322 before extending below a plurality of horizontally extendingfilaments 322 away thecoupling filament 24 to connect to one end of theend portion 336. Theend portion 336 is formed to have a generally arcuate configuration to contact a selected horizontally extendingfilament 322. The connectingportion 337 extends from theend portion 336 over a plurality of horizontally extendingfilaments 322 before extending below a plurality of horizontally extendingfilaments 322 away thecoupling filament 24 to connect to one end of theend portion 334. - When the connecting
portion 335 extends from one end theend portion 334 over a plurality of horizontally extendingfilaments 322, the connectingportion 337 extends below the same plurality of horizontally extendingfilaments 322 to connect to another end of theend portion 334. Similarly, when the connectingportion 335 extends below a plurality of horizontally extendingfilaments 322, the connectingportion 337 extends from one end of theend portion 336 above the same plurality of horizontally extendingfilaments 322. Because of this intersection, each loopedsegment 332 can be referred to as being in a ∞ shape. - To distribute stress and reduce strain on the
belt 310, adjacent loopedsegments 332 can haverespective end portions 336 contacted with different horizontally extendingfilaments 322, as shown inFIG. 8 . Alternatively, adjacent groups of loopedsegments 332 can haverespective end portions 336 contacted with different horizontally extendingfilaments 322, with looped segments of each group having anend portion 336 contacted with the same horizontally extendingfilament 322. -
FIG. 9 shows abelt 410, which is substantially similar in construction and operation as thebelt 10 shown inFIG. 1 , but with certain vertically extendingfilaments 20 removed from thebelt 410. Some vertically extendingfilaments 20 can be removed from thebelt 410 to allow easier formation of theseam 17, for example. With some vertically extendingfilaments 20 removed, looped segments, such as loopedsegments FIG. 1 , for example, can be attached to thebelt 410. Ends of the looped segments can be woven about the plurality of horizontally extendingfilaments 22 to attach the looped segments to thebelt 410. The removal of some vertically extendingfilaments 20 can eliminate the need to form holes in thebelt 410 prior to attachment of the looped segments. - As illustrated, the vertically extending
filaments 22 are grouped in groups of five filaments. In eachgroup 412, every third and fifth vertically extending filament 22 (as shown left to right inFIG. 9 ) is removed from thebelt 410, thus leaving the first, second and fourth vertically extendingfilaments 22 to form sufficient support in the machine direction for thebelt 410. Other configurations are possible and can be used as well. For example, each group can include more or less filaments, each group can include equal or different numbers of filaments or different filaments from each group can be removed. -
FIG. 10 shows theprocess belt 10 operatively engaged with a processing machine, which can be a board processing machine or other paper converting machine, generally indicated at 500, for example in a paper production facility. In general, theboard processing machine 500 includes a plurality of belts suspended from a plurality of rollers, some of which can be driven, to effect transport of paper or board material or stock from one point in the production facility to another. - As illustrated in this embodiment, the
board processing machine 500 is a pressed board machine configured to process press board. In this embodiment, theboard processing machine 500 can include theprocess belt 10 trained around a series of processing rolls 502 and anotherprocess belt 504 which together pull a board product or other paper product (not shown) therethrough. The board product can include two or more board layers, which are to be joined to one another by a suitable adhesive in theboard processing machine 500. The board layers are brought together at one end of theboard processing machine 500 and are pulled across a hot roll 506 (or a series of hot plates) by thebelts 10, 102 to dry and/or to cure the adhesive which bonds the board layers together. Abelt 508 operatively associated with thehot roll 506 can carry the finished board product to another part of the paper production facility. - The
board processing machine 500 is not limited to pressed board machines, but can be any processing machine capable of exerting high machine speeds or high stresses onto the belt and requiring a high number of operational cycles. For example, theboard processing machine 500 may be able to process oriented strand boards or joists in addition to pressed board. -
FIG. 11 shows a flow chart illustrating a method of manufacturing a process belt for use in a board processing machine to process a board stock or other paper product. The method starts at 600. At 602, a body portion of the process belt is formed to have a first end section and a second end section. The body portion can be formed in many ways, one of which includes positioning a first plurality of elongated resilient filaments in a first direction and positioning a second plurality of elongated resilient filaments in a second direction transverse to the first direction. The first plurality of elongated resilient filaments and the second plurality of elongated resilient filaments can be woven together in a conventional manner, for example, manually or mechanically, in any known weave pattern or may be bonded or fused together. - At 604, at least one first looped segment is attached to the first end section of the process belt and at least one second looped segment is attached to the second end section of the process belt. The first and second looped segments extend between the first end section and the second end section of the process belt and can be aligned to receive at least one coupling filament therethrough. The first and second looped segments can be attached to the first and second end sections of the process belt in various ways, for example, by weaving or bonding as described above with respect to
FIGS. 1-9 . Other ways of attaching the first and second looped segments to the respective first and second end sections of the process belt can be used as well. - At 606, at least one coupling filament operatively connects the first end section to the second end section. For example, the coupling filament can be inserted, for example, manually or mechanically, through the first and second looped segments to form a continuous seam between the first end section, the second end section and the body portion. That way, the first end section, the second end section and the body portion are substantially continuous with respect to one another. End portions of the coupling filament can be bent over a number of the first and second looped segments to fixedly secure the coupling filament within the first and second looped segments. At 608, the method ends.
- While the present invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the invention.
- Thus, the foregoing embodiments have been shown and described for the purpose of illustrating the functional and structural principles of this invention and are subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
