Definitions
- the invention relates to a tensioning machine for heat treatment a textile web corresponding to the Preamble of claim 1.
- the web of goods for example, when it is received in needle bars
- the web of goods has its heat treatment inside the tenter in the area of the web infeed often a lower width tension on than at the web outlet, where the shrinkage of the Weft threads and / or warp threads has expired and one Final stability of the web is reached.
- DE-A-195 20 637 describes a tensioning machine for heat treatment a textile web known in the sense of a continuously constant product quality Misorientation of the web (in particular strong deflection movements of the web in the direction of one and / or other side) immediately recognized and can be corrected reliably.
- the Web with regard to sag with the help of Light transmitters and receivers continuously monitored. When a predetermined sag is exceeded a rule intervention for returning sagging web sections in the area of the web transport level performed.
- Tensioner will be those emitted by the light transmitters Rays of light essentially in the longitudinal direction directed by the tensioner, the Rays of light on one side of the web approximately in Direction of transport and on the other side of the web approximately opposite to the direction of transport of the web be sent through the tenter.
- the order of light transmitter and light receiver outside The tensioning machine is particularly suitable for high-temperature applications Tensioner designs such as dryers and / or fusing machines of particular advantage.
- the invention is therefore based on the object Tensioning machine for the heat treatment of a textile web according to the preamble of claim 1 to improve that the means of detecting a Sag of the web without problems even at high temperatures Tensioners can be used and also a localization of the sag in the direction of transport enable.
- the means for recognizing a Sag of the web by two at a distance from each other arranged contact elements formed at a predetermined sag of the web with this in Come into contact, thereby closing a circuit becomes.
- the contact elements are also with a Control device in connection when closed Circuit correcting the sag of the web causes.
- the invention makes use of the idea that at wet material webs can also be used with usable current signals are achieved.
- the current signals increase with increasing Dryness of the textile web is less, however in the area of sag detection, namely in the first fields of the tensioning machine, i.e. in the wet area, so large that a corresponding control signal is generated can be.
- the reduction of at least transversely to the direction of transport sag of the web arising from the web can be realized particularly easily if the device for heat treatment of the web Nozzle devices for inflating tempered gases the side of the web facing them is formed.
- a control intervention to correct the sag can then in particular by changing the gas flow, especially with regard to the amount of gas from the nozzles of the Nozzle devices are made.
- the control device stands in this case, for example, with the blower Nozzle device for changing the speed or a Adjustment flap inside the nozzle device in Connection.
- the contact elements can be used, for example, as contact rails or contact roles are formed.
- the contact elements can be in the transport direction of the web arranged side by side or one behind the other become.
- a tensioning machine 1 is for heat treatment, especially for drying and / or fixing a textile Web 2 formed.
- the web 2 will during this heat treatment in the wide-spread state continuously through the tenter 1 transported through.
- the tensioning machine 1 contains a machine housing in the usual way 3, in its longitudinal direction in several Treatment zones can be divided and at his one end a web inlet 4 and at his at the other end a web run 5 - each in about Form of a transverse slot - has.
- the Material web 2 is thus in during its heat treatment Longitudinally transported through the tensioner 1.
- the direction of transport is with arrow 6 (Fig.1) marked.
- tensioning or transport chains 7, 8 are provided, those with clamps or needle bars like this are equipped that the web 2 on their two Longitudinal edges 2a, 2b are detected and held can.
- the transverse connection plane between the two Transport chains 7, 8 (in the holding area of the longitudinal edges of the web) is hereinafter referred to as goods web transport plane 9 designated.
- goods web transport plane 9 On at least one side the goods web transport level 9 and with practical Distance from this are nozzle devices 10 in shape of nozzle boxes for the inflation of tempered gases, in particular of warm air on the side of the web facing them arranged.
- nozzle devices 10 in shape of nozzle boxes for the inflation of tempered gases, in particular of warm air on the side of the web facing them arranged.
- the Goods transport level 9 nozzle boxes in the form of a upper nozzle box 10a and a lower nozzle box 10b is provided, with a nozzle device 10 Blower 11 for generating air circulation as well at least one control flap 19 belong to each web side a treatment gas in a required adjustable or controllable amount to be able to supply.
- the location of the web 2 is essentially by the Tension or transport chains 7, 8 and the amount of determined by the inflated gases 10 gases. As already explained at the beginning, there are many Factors such as the structure of the web, its width, the Basis weight of the web, its elasticity and the like, that affect the location of the web 2 can.
- the contact elements on both sides of the web 2 or the web transport level 9 provided.
- the contact elements shown in Figures 4 and 5 12a, 12b and 13a, 13b are spaced apart arranged, curved wire electrodes formed.
- the contact elements 13a, 13b are over Control lines 15a, 15b with the control device 16 connected.
- the control device 16 effects depending on the Control signal of the contact elements a correction of Sag by being in the illustrated embodiment 2 a device via lines 17a, 17b 18 controls to adjust the flap 19.
- Adjustment of the flap 19 can the ratio of the the upper and lower nozzle boxes 10a, 10b flowing Amount of treatment gas can be changed. So will with a sag of the web 2 in the direction of the lower Nozzle box 2b the amount of treatment gas in the lower nozzle box 10b in relation to the upper nozzle box 10a can be increased.
- the contact elements have the particular advantage that also in the hot area of the tensioner, where the Sag occurs as expected, be installed can.
- the tensioning machine shown in Fig.1 consists of three treatment zones or fields, each in two half fields can be divided. Each half field points a separate fan 11.
- 6 and 7 are means 12 ', 13' for recognition a sag of the web 2 according to a second Embodiment shown.
- the contact elements by contact rollers 12'a, 12'b or 13'a, 13'b formed.
- the contact rollers offer when touched with the web 2, as shown in Figures 6, 7 is, according to the contact rails Fig. 4 and 5 larger contact area. Otherwise in in an analogous manner by contacting the web with the related ones both contact roles the circuit closed.
- FIG 3 is a clamping machine 1 'according to a second Embodiment shown, which is different from the embodiment according to Figure 1 only in the type of generation the air circulation differs within a half field. While according to Fig.1 for the upper and lower Nozzle box 10a, 10b only one blower 11 and a cooperating with this adjustment flap 19 is provided was, are for the embodiment according to Fig.3 for the upper and lower nozzle boxes, respectively separate blowers 11a, 11b are provided. There is no need to follow this in this embodiment, the adjustment flap.
- means are also in this embodiment provided to detect a sag of the web, which cooperate with a control device 16.
- the one to be effected by the control device 16 Any slack correction can be done with this Embodiment by changing the speed one or both fans 11a, 11b.
- the contact elements shown in Figures 4 and 5 or 6 and 7 are particularly characterized by that they can be used in the hot area of the clamping machines without any problems can be arranged and also special can be manufactured inexpensively.
