Definitions

  • an apparatus which is adapted to be arranged in front of a contact cylinder dryer for predrying, by means of hot air, fabric warp continuously fed to the contact cylinder dryer.
  • the inventive apparatus incorporates outlet slot means for a current of hot air, such outlet slot means extending throughout the entire width of the yarn field and being directed approximately perpendicular towards such yarn field.
  • a suction slot means is situated at the opposite side of the yarn field in the extension of the outlet slot means. This suction slot means extends throughout the entire width of the yarn field and is directed approximately perpendicular thereto.
  • means are provided for producing an air current from the outlet slot means to the suction slot means such that the quantity of air sucked per unit of time through the suction slot means is at least equal to the quantity of air discharged per unit of time from the outlet slot means.
  • the present invention relates to a new and improved apparatus arranged in front or ahead of a contact cylinder dryer and serving to pre-dry by means of hot air a fabric warp continuously delivered or fed to the aforementioned cylinder dryer.
  • pre-dryer it is conventional practice, especially with sizing machines, to conduct the freshly sized warp through a socalled pre-dryer at a location between its discharge from the sizing machine and prior to its entry into a contact cylinder dryer.
  • pre-drying operation occurs by means of hot air or unsaturated vapor which is conducted to the wet dividing zone between the sizing machine and the contact dryer.
  • chamber or compartment dryers in which a hot vapor air mixture is applied to the warp which is divided into different stages or stories.
  • Considerable drawbacks are also associated with these known pre-dryers, especially those which manifest themselves through the great service requirements which are necessary for the insertion of the dividing rods for distribution or division of the warp and which are also necessary in order to remove rupture of the fibers or yarn.
  • a further species of known pre-dryers is engendered by the so-called plane or horizontal dryer which operates with hot air.
  • Such type dryers are only suitable for working with warps having a small number of yarns or yarn count. This is because upon passage of the warp through such a pre-dryer, all of the yarns of the 3,605,282 Patented Sept. 20, 1971 warp are placed into a plane which, in turn, naturally, requires a very large structural length of such a pre-dryer, and accordingly, a very great expenditure of energy for the quantity of hot air, which for high yarn counts becomes uneconomical. Additionally, such plane dryers exhibit the drawback that, especially with compact warps, the freshly sized yarns tend to bond to one another.
  • pre-dryers have the disadvantage that they require a longer heat-up time and a corresponding longer cooling time. Additionally, they possess components which tend to store the pre-drying heat or thermal energy which, in turn, is dangerous since during interruptions of the operation during transport of the warp, even if the pre-dryer is simultaneously shut down, the lengthwise section of the warp which remains stationarily within the confines of the pre-dryer tends to become overdried.
  • pre-dryer constructions which are known up to the present are additionally not very suited for a rapid responsive temperature regulation, or at the very least, are poorly suited for such, and in the case of universal machines, which should selectively operate with or without a pre-dryer, they are not readily suitable since they can only be removed with extreme difficulty.
  • Still another significant object of the present invention relates to an improved apparatus of the mentioned type which provides for an efiicient and controlled pre-drying of warp.
  • Still further significant objects of the present invention are the provision of an improved apparatus adapted to be arranged in front of av contact cylinder dryer for predrying by hot air fabric warp continuously fed to the contact cylinder dryer, which apparatus:
  • the inventive apparatus is generally manifested by the features that it possesses an outlet slot means for a current of hot air which extends substantially over the entire width of the yarn field and is directed approximately perpendicular towards such yarn field. Furthermore, at the opposite side of said yarn field in the extension of the outlet slot means, there is provided suction slot means. Such suction slot means extend substantially throughout the entire width of the yarn field and directed approximately perpendicular to such yarn field.
  • the invention contemplates the provision of means for generating an air current from the outlet slot means to the suction slot means in a manner such that the quantity of air sucked per unit of time through the suction slot means is equal to or greater than the quantity of air which is ejected per unit of time from the outlet slot means.
  • FIG. 1 schematically illustrates an installation incorporating a warp beam frame, sizing machine, apparatus for pre-drying, cylinder dryer and wind-up apparatus;
  • FIG. 2 schematically shows in side view details of the components associated with the pre-drying apparatus of the arrangement of FIG. 1, while omitting for convenience in illustration the other components or members not directly associated with such pro-drying apparatus;
  • FIG. 3 is a schematic top plan view of the apparatus for pre-drying and the cylinder dryer.
  • FIG. 4 is a vertical sectional view taken through the discharge or outlet slot means of the apparatus for predrying shown in the general arrangement of installation of FIG. 1.
  • FIG. 1 there is illustrated the course of travel of a fabric warp K which is drawn off a warp beam frame unit 1.
  • This fabric Warp K passes through a suitable sizing vat 2 in which it is sized, and upon leaving the sizing vat 2 this warp K passes through a region conveniently designated as a wet dividing zone 3, to finally arrive at the drum means 4 of a contact cylinder dryer arrangement.
  • a beaming or wind-up machine 5 onto which is wound the sized and now dried warp K.
  • a hood member 6 above the cylinder dryer arrangement 4 can also be considered known to the art.
  • This hood member 6 opens or communicates with a withdrawal channel or duct 7 in which there is housed a suitable ventilator 8.
  • the ventilator 8, or equivalent structure serves to withdraw the air saturated with moisture appearing at the cylinder dryer arrangement 4.
  • suitable articulated flap or valve members 9 directly after the hood member 6 within the confines of the duct or channel 7 there are arranged suitable articulated flap or valve members 9, by means of which it is possible to regulate the Withdrawal of air through the hood member 6.
  • the apparatus for carrying out the pre-drying operation and which constitutes the primary aspect of the present invention, will be seen to be arranged at the region of the wet dividing zone 3. Its purpose is to prevent the sticking or adhering together of the fibers or yarns of the freshly sized warp K. Additionally, this pre-drying apparatus is intended to also subject to a drying operation the flanks or sides of the yarns which are not placed into contact with the drying drums of the cylinder drying arrangement 4.
  • the illustrated apparatus for pre-drying utilizes parts or components of the existing cylinder dryer, especially its air withdrawal duct or channel 7 and the ventilator 8. It will be seen to further encompass a withdrawal hood member 10 which is directed approximately vertically and the opening of which forms a suction slot means 11 arranged directly over the warp K and extending over the entire width of this warp and approximately directed perpendicular thereto. Continuing, it will be recognized that the upper end 10a of the hood member 10 opens into the channel or duct 7, and furthermore, between the suction slot means 11 and the opening into the duct 7 there are arranged articulated flap or valve means 12 which enable regulation or control of the passage of air through the hood member 10.
  • a substantially slot-shaped outlet means 13 for a current of hot air and which is directed toward the suction slot means 11.
  • This outlet or discharge slot means 13 likewise extends approximately perpendicular to the warp K throughout the entire width thereof.
  • a large number of lamellae or fins 14 which are in parallelism with one another and which subdivide the outlet slot means 13 into substantially vertically extending channels 14a. It is also seen by referring to this figure that these lamellae or fins 14 are secured to a heating coil 15 extending into the outlet slot means 13.
  • the air current delivered to the outlet slot means 13 is produced by the ventilator or fan 8 arranged in the duct or channel 7. T 0 this end, there are operatively connected in flow communication with the duct 7, at opposite sides of this duct, and downstream of the ventilator 8 in the direction of flow, two branch channels or ducts 16 and 17. These branch ducts or channels 16 and 17 are downwardly directed at both sides of the sizing vat 2 and conducted beneath such sizing vat, to finally open into opposite sides of the outlet slot means 13, as best seen by referring to FIGS. 2 and 3. Flap or valve members 18 and 19 serve to regulate the distribution of the air current produced by the ventilator *8 between the duct 7 and the branch channels or ducts 16 and 17, respectively.
  • a pipe connection or stud 20 Upstream of the ventilator 8, in the direction of air current flow, there is additionally provided at the duct 7 a pipe connection or stud 20 for entry of fresh air into the circulation system, whereby this fresh air infeed can be regulated by a flap or other suitable valve 21 arranged within the pipe connection 20, as best shown by referring to FIG. 1.
  • inventive apparatus for pre-drying a fabric warp lends itself to 'be used universally with an installation equipped with such an apparatus and a cylinder dryer.
  • the illustrated installation can also operate without any pre-drying apparatus. This would then be the case if the air flow directing flaps 18 and 19 assumed the position shown in FIG. 3 in which they close the branch channels or ducts 16 and 17, respectively, and the flaps or valves 12 and 21 are also closed.
  • the ventilator or fan 8 sucks air via the hood member 6 of the cylinder dryer and conducts this air through the channel or duct 7 into the surrounding atmosphere. Hence, the pre-dryer apparatus is not in operation.
  • the air conveyed through the branch channels 16 and 17 to the outlet slot means 13 is uniformly divided and distributed over the entire range of the outlet slot means. Furthermore, a directed air current leaves this outlet slot means 13, the air jets of which form a plane which is perpendicular to the fibers or yarns of the throughpassing warp K.
  • This phenomenon is further supported according to the invention in that according to one important aspect of the described apparatus, the flow conditions are adjusted by means of the flap members and the fins in such a manner that the quantity of hot air sucked per unit of time through the suction slot means 11 is greater than the quantity of air which is ejected or discharged from the outlet slot means 13 per unit of time. Consequently, there exists a heating phase which acts throughout the yarn field with a minimum of losses in thermal energy due to lateral radiation.
  • This hot air current acts, in the first instance, upon the flanks or sides of the yarns, exactly upon those locations which are neglected during the drying operation in the subsequently arranged cylinder dryer arrangement 4.
  • the pre-drying of just these flanks or sides of the yarns can, however, depending upon the make up of the warp and especially for thick warps, be of decisive importance in order to prevent the sticking or adhering together of the yarns of the warp.
  • the described apparatus can be quickly and precisely adjusted, whereby the heating efficiency and the air quantity can be adjusted or regulated equally well for slow operations as well as for normal speed operations.
  • the air current can momentarily be interrupted.
  • there are neither present chamber walls nor housing walls there is also, during shut down of the pre-dryer, no heat radiation onto the warp by heated metallic parts and, thus, there does not occur any overdrying of the warp section which is at standstill in the pre-dryer.
  • An apparatus adapted to be arranged in front of a contact cylinder dryer for pre-drying by means of hot air fabric warp continuously fed to the aforesaid contact cylinder dryer, comprising means defining outlet slot means for a current of hot air, said outlet slot means extending throughout substantially the entire width of the yarn field and being directed approximately perpendicular to such yarn field, means defining a suction slot means situated at the opposite side of said yarn field in the extension of said outlet slot means, said suction slot means extending throughout substantially the entire width of said yarn field and being directed approximately perpendicular to said yarn field, said suction slot means and said outlet slot means being vertically aligned, fin means in substantial parallelism with one another for subdividing said outlet slot means into vertical channels, so that during operation a directed air current forms between said outlet slot means and said suction slot means, the air jets of which are disposed in a plane which is substantially perpendicular to the yarns of the throughpassing warp, and means for producing an air current from said outlet slot means to said suction slot
  • An apparatus as defined in claim 2 further including controllable air infeed opening means for fresh air communicating with said withdrawal duct means, said air infeed opening means being arranged downstream of said articulated flap means in the flow direction of the air current through said withdrawal duct means.
