Definitions
- the present invention relates to a nonwoven layer for laying a nonwoven fabric from a card web.
- Nonwovens serve to deposit the card web produced by a carding machine as evenly as possible on a delivery conveyor belt in multilayered layers to form a nonwoven.
- the card web is usually first passed through a superstructure and from there to a laying carriage, through the Ablegespalt the card web is placed on the delivery conveyor belt.
- At least two pile conveyor belts serve to guide the card web through the nonwoven layer. The movements of the pile conveyor belts, the superstructure and the laying carriage are controlled in a coordinated manner.
- the EP 2 479 321 A1 discloses a simplified construction of a batt layerer in which the masking tape is smooth and is not moved along with the card web, but serves as a quasi-stationary cover for the card web. To ensure that the cover tape includes the card web as long as possible on the web conveyor belt, the masking tape extends from an attachment point in the inlet region of the web layer through the upper carriage to a second attachment point at the other end of the web layer.
- a disadvantage of this configuration is that it comes to high relative velocities between the stationary cover band and the transversely moved back and forth superstructure when the masking tape looped through the superstructure becomes. This results in particular in the area of the deflection in the superstructure a heavy burden and increased wear of the cover.
- the present invention is therefore an object of the invention to provide a nonwoven, in which the supplied pile is securely guided and the forces acting on the cover are reduced.
- the nonwoven laying for laying a fleece from a card web on a transversely movable superstructure, through which the card web is guided, also a movable in the transverse direction laying carriage, which is guided by the upper cart coming from the upper web and the delivery of the card web on a delivery conveyor belt serves.
- the nonwoven depositor has at least two pile conveyor belts for guiding the pile web to the upper carriage and further to the laying carriage, wherein a first circulating pile conveyor belt whose upper run extends from an inlet region of the web laying machine to the upper carriage and serves as a bearing surface for the card web forms a rough pile transport belt is located above the upper run of the first Flortransportbandes a cover for covering the resting on the upper run of the first Flortransportbandes pile web from above, wherein the cover portion as a portion of a cover strip or as a portion of a Schar of spaced and parallel juxtaposed linear elements is formed, wherein the cover strip or the linear elements are formed smooth and the card web is moved along the underside of the cover along.
- the cover strip or the family of linear elements in the region of a first end section is connected to the superstructure and the nonwoven layer also has a compensation mechanism for compensating for the length of the cover section changing in the transverse direction when the upper carriage moves.
- the nonwoven laying on a counter to the superstructure in the transverse direction back and forth movable clamping carriage, which is part of the compensation mechanism and to which a second end portion of the cover strip or the family of linear elements is connected.
- the compensation of the length of the cover section which changes in the transverse direction during the process of the superstructure can be implemented particularly simply in terms of design.
- cover strip or the group of linear elements is deflected in the inlet region of the web laying and at least the second end portion of the cover strip or the family of linear elements substantially parallel to the upper strand of the first Flortransportbandes led to a recording on the tensioning carriage and on the Recording is attached.
- This design is particularly well suited for space-saving housing and simple structural design of the compensation mechanism.
- the receptacle is formed on a rail and more preferably the tensioning carriage is arranged below the upper run of the first pile conveyor belt and the rail between two clamping brackets, which are mounted laterally on the tensioning carriage and protrude from this up above the upper run of the first pile conveyor belt.
- the same tensioning carriage can be used to compensate for the changing length of the cover portion and for keeping constant the loop length of the first pile conveyor belt in the process of transversely of the superstructure. This represents a cost-effective solution in which no additional control and regulation costs incurred and the design effort is greatly reduced.
- a blowing of the card web can be prevented as completely and effectively as possible, it is also advantageous if in a section between an attachment point of the first end portion of the cover strip or the family of linear elements in the upper carriage and a transfer point of the card web on the second Flortransportband at least a first card web guide means is provided, which guides the card web in this section, wherein the card web is enclosed between the at least one first card web guide means and the first pile conveyor belt. It is particularly preferred if the attachment point of the first end portion of the cover strip or the Group of linear elements in the superstructure is part of the first Flordahn Entrys Adjustsmittels.
- the card web is in this case continuously covered and enclosed between the cover portion or the first card web guide means and the first pile conveyor belt, whereby particularly high web feed speeds are made possible.
- At least one second card web guide means is provided for guiding the card web in that portion, the card web between the at least one second card web guide means and the first pile conveyor belt is included.
- the cover strip is designed to be permeable to air to z. B. to allow the escape of entrained air from the card web.
- cover strip is made impermeable to air, so that a particularly secure cover and leadership of the card web is ensured by the cover.
- the masking tape is preferably formed from a fabric carrier coated with Teflon or PVC.
