- FIG. 1 a system for ironing cloth, designated broadly at 10, is shown in FIG. 1 .
- the system 10 includes an enclosure 12 that includes a base 14 (also referred to as a "chest") that provides support from underneath.
- Two cylindrical rolls 16 are positioned within semicircular recesses 18 in the chest 14.
- the rolls 16 are perforated and are hollow.
- Each of the rolls 16 is covered with a felt 22 that is wrapped around the circumference of the roll 16, with an overlapping section 38 present at one end of the felt 22.
- a steam generation system 20 is operatively associated with the chest 14.
- a suction unit 24 is fluidly connected to the cavities of the rolls 16.
- a cloth 30 to be ironed (for example, a bed sheet, cloth for tailored clothing, tablecloths, or the like) is fed between the chest 14 and the rolls 16, with the rolls 16 rotating about their longitudinal axes A to convey the cloth 30.
- the nip between each felt 22 and the underlying recess 18 of the chest 14 is sufficiently narrow that the cloth 30 is pressed between these structures.
- Steam is generated in the steam generation system 20 and released through the chest 14 into the cloth 30.
- the suction unit 24 draws the steam through the cloth 30 and the felt 22 and into the cavities of the rolls 16 through the perforations in the rolls 16.
- the heat, steam and pressure help to remove wrinkles in the cloth 30.
- the steam exits the rolls 16 and is conveyed to a heat exchanger (not shown) for cooling and/or re-use.
- the felt 22 is multi-layered and comprises at its core a base layer comprising a plurality of yarns 32.
- the yarns 32 extend parallel to each other in the machine direction as defined above.
- the felt 22 has no yarns extending in the cross-machine direction that weave with the yarns 32.
- the yarns 32 are shown as being arranged in a single layer, but in other embodiments the yarns 32 may be arranged in multiple layers, typically with a scrim or batt layer present between the layers of yarns.
- the yarns 32 may be formed of a variety of forms, including monofilaments, multifilaments, spunbond yarns, staple yarns, and twisted combinations thereof, and with a variety of materials, such as aramid, polyester, polyamide, polyphenylene sulfide (PPS), and the like.
- the yarn sizes may also vary; typically the yarns are between about 30 and 300 tex.
- Yarn spacing may also vary; in a typical felt, the spacing between the yarns 32 creates a yarn density of between about 6 and 12 yarns per cm.
- the yarn material, size and spacing should be selected so that the overall felt 22 has a tensile strength in the machine direction of at least 300N/cm, and/or has an elongation resistance of less than 0.26 percent in operation, and an overall elongation of 25 percent to failure.
- the felt 22 also includes batt layers 34, 36 that overlie and underlie the yarns 32.
- the batt layers 34, 36 are typically formed of a variety of materials, such as aramid, polyester, polyamide, PPS, and the like, and combinations thereof, although other materials may also be employed. Although the batt layers 34, 36 are shown as single layers, either or both of the batt layers 34, 36 may include multiple layers, which may be formed of the same or different materials. Ordinarily, the batt layers 34, 36 are applied to the yarns 32 by a needling process.
- FIG. 3 shows a comparison of the felt 22 with a conventional felt 22'.
- the conventional felt 22' includes batt layers 34', 36' and a woven fabric 32' serving as a base layer that comprises MD yarns 32M interwoven with CMD yarns 32C.
- the MD yarns 32M follow a sinuous or crimped path in interweaving with the CMD yarns 32C.
- the crimping of the MD yarns 32M effectively creates some slack in the MD yarns 32M, such that, when the conventional felt 22' is placed under tension in the machine direction (which occurs during operation as the rolls 16 rotate relative to the chest 14 ), the conventional felt 22' tends to elongate in the machine direction.
- the yarns 32 of the felt 22 have no crimping because they do not interweave with other yarns. As such, when placed under tension in the machine direction during operation, the yarns 32 have little to no slack, and thus resist lengthening (i.e., have low elongation) considerably more than the MD yarns 32M of the conventional felt 22'. If a felt stretches too much, it may become necessary to cut back the overlapping section 38 with some frequency, during which operations cease. The felt 22 may provide sufficient elongation resistance to prevent elongation during operation that would require cutting of the overlapping section 38. Also, because the felt 22 has no CMD yarns, the overall weight of a felt with similar or improved elongation resistance can be lower. Further, the absence of CMD yarns within a woven fabric (i.e., the use of only MD yarns) can reduce the cost of the felt significantly, as the weaving process can be omitted.
- a felt 22 includes yarns 32 formed of aramid included in a density of 200g/m 2 , and batt layers 34, 36 formed of aramid and having a thickness of 4.7 mm, thereby providing a felt having an overall density of 800g/m 2 .

- Well-known functions or constructions may not be described in detail for brevity and/or clarity.
- Referring now to the figures, a system for ironing cloth, designated broadly at 10, is shown in
FIG. 1 . Thesystem 10 includes anenclosure 12 that includes a base 14 (also referred to as a "chest") that provides support from underneath. Two cylindrical rolls 16 are positioned withinsemicircular recesses 18 in thechest 14. The rolls 16 are perforated and are hollow. Each of the rolls 16 is covered with afelt 22 that is wrapped around the circumference of the roll 16, with an overlappingsection 38 present at one end of the felt 22. Asteam generation system 20 is operatively associated with thechest 14. Asuction unit 24 is fluidly connected to the cavities of the rolls 16. - In operation, a
cloth 30 to be ironed (for example, a bed sheet, cloth for tailored clothing, tablecloths, or the like) is fed between thechest 14 and the rolls 16, with the rolls 16 rotating about their longitudinal axes A to convey thecloth 30. Typically the nip between each felt 22 and theunderlying recess 18 of thechest 14 is sufficiently narrow that thecloth 30 is pressed between these structures. Steam is generated in thesteam generation system 20 and released through thechest 14 into thecloth 30. Thesuction unit 24 draws the steam through thecloth 30 and the felt 22 and into the cavities of the rolls 16 through the perforations in the rolls 16. The heat, steam and pressure help to remove wrinkles in thecloth 30. The steam exits the rolls 16 and is conveyed to a heat exchanger (not shown) for cooling and/or re-use. - Referring now to
FIG. 2 , the felt 22 is multi-layered and comprises at its core a base layer comprising a plurality ofyarns 32. Theyarns 32 extend parallel to each other in the machine direction as defined above. As illustrated inFIG. 2 , the felt 22 has no yarns extending in the cross-machine direction that weave with theyarns 32. InFIGS. 2 and 3 , theyarns 32 are shown as being arranged in a single layer, but in other embodiments theyarns 32 may be arranged in multiple layers, typically with a scrim or batt layer present between the layers of yarns. - The
yarns 32 may be formed of a variety of forms, including monofilaments, multifilaments, spunbond yarns, staple yarns, and twisted combinations thereof, and with a variety of materials, such as aramid, polyester, polyamide, polyphenylene sulfide (PPS), and the like. The yarn sizes may also vary; typically the yarns are between about 30 and 300 tex. Yarn spacing may also vary; in a typical felt, the spacing between theyarns 32 creates a yarn density of between about 6 and 12 yarns per cm. In particular, the yarn material, size and spacing should be selected so that theoverall felt 22 has a tensile strength in the machine direction of at least 300N/cm, and/or has an elongation resistance of less than 0.26 percent in operation, and an overall elongation of 25 percent to failure. - The felt 22 also includes batt layers 34, 36 that overlie and underlie the
yarns 32. The batt layers 34, 36 are typically formed of a variety of materials, such as aramid, polyester, polyamide, PPS, and the like, and combinations thereof, although other materials may also be employed. Although the batt layers 34, 36 are shown as single layers, either or both of the batt layers 34, 36 may include multiple layers, which may be formed of the same or different materials. Ordinarily, the batt layers 34, 36 are applied to theyarns 32 by a needling process. -
FIG. 3 shows a comparison of the felt 22 with a conventional felt 22'. As can be seen inFIG. 3 , the conventional felt 22' includes batt layers 34', 36' and a woven fabric 32' serving as a base layer that comprisesMD yarns 32M interwoven withCMD yarns 32C. As shown inFIG. 3 , theMD yarns 32M follow a sinuous or crimped path in interweaving with theCMD yarns 32C. The crimping of theMD yarns 32M effectively creates some slack in theMD yarns 32M, such that, when the conventional felt 22' is placed under tension in the machine direction (which occurs during operation as the rolls 16 rotate relative to the chest 14), the conventional felt 22' tends to elongate in the machine direction. - In contrast, the
yarns 32 of the felt 22 have no crimping because they do not interweave with other yarns. As such, when placed under tension in the machine direction during operation, theyarns 32 have little to no slack, and thus resist lengthening (i.e., have low elongation) considerably more than theMD yarns 32M of the conventional felt 22'. If a felt stretches too much, it may become necessary to cut back the overlappingsection 38 with some frequency, during which operations cease. The felt 22 may provide sufficient elongation resistance to prevent elongation during operation that would require cutting of the overlappingsection 38. Also, because the felt 22 has no CMD yarns, the overall weight of a felt with similar or improved elongation resistance can be lower. Further, the absence of CMD yarns within a woven fabric (i.e., the use of only MD yarns) can reduce the cost of the felt significantly, as the weaving process can be omitted. - In one embodiment, a felt 22 includes
yarns 32 formed of aramid included in a density of 200g/m2, and batt layers 34, 36 formed of aramid and having a thickness of 4.7 mm, thereby providing a felt having an overall density of 800g/m2. - The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims.
