Abstract
A non-woven strip 1 unwound from a roll 11 is applied as contiguous coils to an endless support web 2. Each coil extends at a slight angle of inclination to the longitudinal direction of web 2. This is achieved by fleece band feed device 3, including edge trimmers 12, being moved by carriage 4 on rails 5 transversely of the web 2 as the band 1 is applied. To ensure that adjacent coils are precisely contiguous, the position of the longitudinal edges of the last applied coil 2a and the incoming strip 1 (which edges are to abut) are sensed at 24 and 25 and then compared at 22, at least one aspect of the apparatus being controlled in dependence upon the comparison. The controlled aspect can be in the movement of carriage 4 along rails 5, the angular position of feed device 3 about bearing 17 on carriage 4, the cutting line of trimmers 12 or the speed of strip supply motor 31, this last affecting the tension and thus the width of the strip. <IMAGE>
Description
f APPARATUS FOR APPLYING A NONWOVEN STRIP TO A REVOLVING ENDLESS BACKING
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an apparatus for applying a nonwoven strip to a revolving endless backing to form juxtaposed convolutions thereon, comprising a nonwoven strip feeder, which is movable transversely to the backing and comprises means for trimming that portion of the nonwoven strip which is approaching the backing, and means for detecting the position of the free longitudinal edge of a convolution of the nonwoven strip which has already been applied to the backing and which at said edge is to be contacted by the nonwoven strip portion which is approaching the backing.
2. Description of the Prior Art
It may be desired to apply a nonwoven strip in a plurality of juxtaposed convolutions to a revolving endless backing in such a manner that adjacent edges of adjacent convolutions exactly adjoin each other. For that purpose it is known to automatically control the traversing movement of the backing relative to the feeder in dependence on the longitudinal direction of the convolution formed by the nonwoven strip which 0 has been applied to the backing and is to be contacted by the approaching portion of the nonwoven web or in dependence on the direction of the free longitudinal edge of said convolution. For that purpose it is known (EP-A- 123 969) to supply a marking thread concurrently with the nonwoven strip and to detect by means of a line camera the course of the irlarking thread and to derive thlerefrom a manipulated variable for the control of the means for traversing the backing relative to the feedert which is stationary in that case. For taking into account not only deviations of the convolutions of the nonwoven strip from a predetermined longitudinal direction it is -known (from Austrian Patent Specification 391t676) to detect the free longitudinal edge of each convolution of the nonwoven strip. which edge is to be contacted by the approaching portion of the nonwoven striDg so that adjacent edges of adjacent convolutions of the nonwoven strip can be caused to adjoin each otherp provided that the approaching nonwoven strip portion has been trimmed to ensure a constant width of the nonwoven strip. But it has been found in practice that the width of the approaching nonwoven strip portion will often vary so that adjacent convolutions of the nonwoven strip will not regularly adjoin each other.
SUMLARY OF THE INVENT ION It is an object of the invention so to improve by the use of simple means an apparatus for applying a nonwoven strip to a revolving endless backing that adjacent edges of nonwoven strip convolutions which have consecutively been applied to the backing will reliably adjoin.
The object set forth is accomDlished in accordance with the invention in that means for detecting the position of the contacting edge of the approaching nonwoven strip portion are provided between the trimming means and a line of initial contact between the approaching nonwoven strip portion and the backing, the means for detecting the Dosition of the free longitudinal edge of the previously applied 5 convolution of the nonwoven striD are used as a setpoint generatory the means for detecting the position of the contacting edge of the nonwoven strip portion approaching the backing are used as an actual- value signal generator. and both said generators are connected to a controller, which controls means for controlling in response to a setpoint-actual value comparison the position of the contacting edge of the approaching nonwoven strip portion.
As a result of said measures. deviations of the position of the free edge of the nonwoven strip portion which has been applied will be taken into account as well as variations of the width of the approaching nonwoven strip portion because a position of the free edge of the previously applied convolution of the nonwoven strip is used as a setpoint for a position of the contacting edge of the approaching nonwoven strip portion and the position of that contacting edge can be influenced by suitable control means to eliminate any difference between the setpoint and the actual value.
Various detectors may be used to detect the -position of the contacting edge of the approaching nonwoven strip portion. provided that such detectors can detect the position of that edge with sufficient accuracy without adversely affecting the properties of the nonwoven strip. But particularly desirable 1 conditions from that aspect may be provided by means which comprise an optoelectronic detector, which faces means for deflecting the approaching nonwoven strip portion. because the optoelectronic detector preferably consisting of a line camera may be used for a noncontacting measurement in a manner known per se and the means for deflecting the approaching nonwoven strip portion constitute structure which defines the course of that Dortion relative to the measuring means. 'This is of special significance for the focussing of an optoelectronic detector. which focussing is required for a sufficient resolution.
The means for controlling the position of t-he contacting edge of the approaching nonwoven strip portion may consist of any positioning means for transversely displacing the approaching nonwoven strip portion relative to the backing. For this reason the drive means for traversing the feeder may be used to special advantage for that purpose. On the other hand, the relatively large mass of the entire feeder would give rise to a higher expenditure if a sensitive automatic control is desired. More desirable conditions will be established from that asmect if the mass that is to be moved for a transverse displacement of the approaching nonwoven strip portion can be restricted. as will be the case if the feeder is mounted on a sliding or wheeled carriagel which imparts the traversing movement, and the feeder is pivoted to said sliding or wheeled carriage on an axis -which is transverse to the longitudinal and transverse directions of the approaching nonwoven strip portion and of the backing. In that case an angular movement can be imparted to the feeder to effect a transverse movement Which takes all deviations of the adjacent longitudinal edges of the convolutions and of the approaching nonwoven strip portion from a straight course into account and that transverse movement will be superposed on the transverse displacement imparted to the approaching nonwoven strip portion by the constant traversing movement of the sliding or wheeled carriage. An additional advantage which will be afforded resides in that the approaching nonwoven strip portion will always be oriented at the lead angle at which it is to be applied to the backing.
Alternatively the course of the contacting edge of the approaching nonwoven strip portion may be controlled by a controlled trimming of the contacting edge by a trimming knife, which is associated with that contacting edge and to which a corresponding transverse displacement is imparted. Such a control will afford the advantage that the transverse displacement of the nonwoven strip portion approaching the backing is not affected so that the nonwoven strip portion can be applied at a constant lead angle and a straight course of the contacting edge of the next succeeding convolution of the nonwoven strip will thus be ensured.
A change of the external tensile forces exerted on the nonwoven strip portion approaching the backing will necessarily change the width of that strip portion because an increase of the tensile stress will decrease t-he width of the nonwoven strip.
That effect may also be utilized to control the course of the edge of the approaching nonwoven strip portion if the velocity at which the approaching nonwoven strip portion is fed can be changed correspondingly. The tensile forces exerted on the approaching nonwoven strim portion will depend on the difference between the velocity at which the nonwoven strip is fed and the velocity at which the nonwoven strip is pulled and which depends on the velocity at which the backing is revolving. In that case it may also not be necessary to exert an additional influence on the traversing movement.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIDIENTS
The invention will now be described in more detail with reference to the drawing.
The illustrated apparatus for applying a nonwoven strip to a revolving endless backing 2 essentially comprises a feeder 3 for the nonwoven strip 1. That feeder is movable by a sliding carriage 4 along a trail track 15 tran versely to the backing 2, which has been closed to form a tubular backing and is trained around reversing pulleys 6. The sliding carriage 4 is driven by means of a rack 7, which is parallel to the rail 'Grack 5 and meshes with a pinion 9 that is driven by a motor 8. The feeder 3 comprises means 10 for unwinding a nonwoven strip from a roll 11 and trimming means 12 for trimming the nonwoven strip portion 1 which has been unwound from the roll 11 of nonwoven strip and is approaching the backing 2. The nonwoven strip portion vffiich has been withdrawn from the roll 11 of nonwoven strip initially is permitted to sag freely over a span 13 so that the strip can be relieved from internal stresses which are due to the winding operation and is then placed on a belt con- veyor 14. Between the belt conveyor 14 and a pair of pull-off rollers 15 the nonwoven strip 1 is subjected to a tensile stress so that it can accurately be trimmed by the trimming means 12. The trimmed portion of the nonwoven strip is deflected by deflecting means 16 as it is fed under a predetermined tensile stress to the backing 2. in order to form on the backing 2 one or more nonwoven layers consisting each of a plurality of juxtaposed convolutions 2a which have been applied at a predetermined lead angle.
The nonwoven strip portion 1 which has been pulled from the roll 11 of nonwoven strip and has been trimmed at its edge by the trimming means 12 is to be applied to the revolving backing 2 accurately at the predetermined lead angle. For that purpose the nonwoven strip portion 1 is oriented at the lead angle by the feeder 39 which is pivoted on the sliding carriage 4 by means of a swivel bearing 17 on a pivotal axis which is transverse to -,,-he longitudinal and transverse directions of the nonwoven strip portion and of the backing 2 adjacent to the line of initial contact 18 at which the nonwoven strip portion 1 is applied to the backing 2. Said pivotal axis is spaced from said line of initial contact 18.
The feeder 3 is angularly movable relative to the sliding carriage 4 by a swiveling cylinder 19p which is pivoted to the sliding carriage 4 and to the feeder 3 and can be supplied with pressure fluid at both ends. That supply of pressure fluid is controlled by suitable valves 20 in the pressure fluid supply lines. only one of which is schematically indicated in Figure 1 for the sake of simplicity. The actuator 21 for each of said valves 20 is controlled by a controller 22, which is connected to an angle encoder 23 for indicating the instantaneous angular position of the feeder 3 relative to the sliding carriage 4. The controller 22 is also connected to means 24 for detecting the position of the free longitudinal edgeof that convolution 2a of nonwoven strip which has already been applied. i.e., the position of that longitudinal edge at which said convolution is to be contacted by the nonwoven strip mortion that is approaching the backing 2. The con- troller 22 is also connected to means 25 for detecting the position of the contacting edge of the nonwoven strip portion approaching the backing. The means 25 for detecting the Dosition of that longitudinal edge of the approaching nonwoven strip portion 1 with which 9 - said nonwoven strip portion is to contact the previously applied convolution 2a of the nonwoven strip preferably consist of a photoelectronic detector 269 such as a line camera, which detects the contacting edge la of the nonwoven strip portion 1 adjacent to the means 16 for deflecting the nonwoven strip portion 1 between the pull-off rollers 15 and the line of initial contact 18 so that structural means determine the association of the nonwoven strip portion to the optoelectronic measuring meansg which accurate association is required for an accurate detection of the position. A light source 27 for illuminating that edge of the nonwoven strip which is to be detected is suitably provided on that side of the deflecting means 16 which is opposite to the line camera 26. The deflecting means 16 suitably exert a spreading action on the nonwoven strip and for that purpose are cambered and adjacent to that edge of the nonwoven strip which is to be scanned are formed with an aperture 28,, through which light can be projected onto the edge of the nonwoven strip or through which said edge is exposed to the line camera.
To ensure that the adjacent edges of adjacent convolutions 2a of the nonwoven strip will exactly contact each other, means are provided for deriving from the output of the means 24 a setpoint signal representing a position of the free edge of the convolution 2a of the nonwoven strip at the line of initial contact 18 in the direction of the width of the backing, means are provided for deriving from the output of the detector 25 an actual-value signal reDresenting a position of the contacting edge la of the approaching nonwoven strip portion 1 at said line of initial contact 18 and the approaching nonwoven strip portion 1 is adjusted to offset any deviation of said actual-value signal from said setpoint signal so that the approaching nonwoven strip portion 1 closely adjoins the previously applied convolution 2a of the nonwoven strip. 'When the controller 22 detects a difference between the setpoint and the actual value, the motor 8 for traversing the sliding carriage can properly be controlled to eliminate the deviation which would otherwise occur between the adjacent edges of the adjacent convolutions.
The position of the edge may also be controlled in that the valve 20 is controlled in dependence on a comparison of the setpoint and the actual value and in that case the output signal of the means 24 for detecting the position of the free longitudinal edge of the previously applied convolution 2a of the nonwoven strip may be used as a reference input for the control of the lead angle at which the nonwoven strip is to be applied to the backing 2.
A different control can be performed if the trimming means comprise cutting tools 29, which are transversely adjustable during the trimming operation and with which adjusting means 30 are associated, which are controlled by the controller 22. By means of said cutting tools 29. which can be adjusted across the nonwoven stript the contacting edge of the approaching nonwoven strip portion can be trimmed to deviate from a straight course in dependence on a detected difference between the setpoint and the actual value.
The pair of pull-off rollers 15 which are ass.ociated with the trimming means 12 are driven by a motor 31 t which drives also the belt conveyor 14 at a predetermined transmission ratio to the pull-off rollers so that a constant tensile stress for the trimming operation can be exerted on the approaching nonwoven strip portion. That motor 31 may also be controlled by the controller so that under constant tension conditions adjacent to the trimming means the velocity at which the nonwoven strip portion 1 is fed to the backing 2 can automatically be controlled in dependence on a comparison of a set-point and an actual value. A progressive decrease of the velocity at which the approaching nonwoven strip portion 1 is fed relative to the generally constant velocity at which the backing 2 revolves will result in an increase of the tensile stresses in the nonwoven strip portion between the trimming means and the line of initial contact between the nonwoven strip portion and the backing and the width of the nonwoven strip will thus be decreased. In that manner an adaptation can be effected to any deviation of the course of the free edge of the previously applied convolution of the nonwoven strip. An increase of the velocity at which the approaching nonwoven strip portion 1 is fed will obviously have the opposite effect to widen the nonwoven strip.
It will be understood that the invention is not restricted to the embodiment shown by way of example. For instancel each of the measures used to control the course of the edge of the nonwoven strip portion approaching the backing may be adopted alone or in any desired combination if this is required under given conditions.
