Definitions
- the invention relates to a method and an apparatus for coating a Thread sheet with at least one size compartment for contacting the yarn of the sheet with sizing liquor and at least one sizing squeezer that separates from each other pressed rollers.
- GB-A 830 836 describes a method and a device for automatic control a continuous application of a certain amount of solid or liquid on a moving web, e.g. Paper, described.
- a moving web e.g. Paper
- the center distance between two rollers of a crushing unit is varied by a mechanical lifting gear.
- sizing devices In sizing devices, it is customary to treat the thread sheet to be treated with a sizing liquor to act, especially to dive in a trough and then in a Squeeze out excess sizing. Such a device is in DE 32 03 087 A1 described.
- measuring devices so-called order measuring devices, which allow the amount of measure the size remaining on a thread sheet after squeezing. With The squeeze pressure controller can be controlled from the measured values.
- order measuring devices allow the amount of measure the size remaining on a thread sheet after squeezing.
- the squeeze pressure controller can be controlled from the measured values.
- Such measuring systems are specified in DE 42 34 279 A1.
- the degree of sizing of a thread group can be dependent, among other things it can also depend on their pretreatment, for example on the original moisture be of the speed with which the size is applied and squeezed off it may continue to depend on the concentration of the applied Plain. If a certain amount of size is desired, the Order measuring devices mentioned, under certain circumstances in several places, e.g. before Finishing and after squeezing. The measurement results are used with the aim of the squeezing pressure, that is the specific surface pressure of the squeeze mechanism to be regulated so that the specified amount of size on the thread sheet remains.
- the invention has for its object the accuracy of the setting of To improve the squeezing pressure and to make the control essentially hysterical, without limiting the speed of reaction.
- the invention is based on the finding that the center distance of the Squeeze rollers change proportionally to the surface pressure and thus to the squeezing effect. This proportionality applies particularly to those moistened when squeezed or sized thread groups usual pressure ranges.
- a cylinder pressure specification hydroaulic or pneumatic
- the invention is the mutual Distance between the roller axes - that is, a path directly. Surprisingly provides the immediate and therefore arbitrarily quick path setting a reproducible and hysteresis-free measured value proportional to the surface pressure of the crushing mechanism and thus to the squeezing effect.
- the squeezing pressure is determined by directly specifying path values, namely the center distance, regulated.
- the respective path can be i.e. agents without delay, e.g. through a mechanical Hoist gear or a spindle gear but also by hydraulic or pneumatic Lifting elements, with increasing and falling pressure the same or exactly reproducible adjust so that the object underlying the invention in almost ideally is solved. If in the present context of freedom from hysteresis the squeeze pressure setting is spoken, it means that the Squeeze pressure specification within the desired accuracy is hysteresis-free.
- the surface pressure f (N / cm 2 ) is essentially proportional to the values of the center distance A between 90 and 100%.
- the values 95% and 90% correspond to smaller center distances where rolls 1 and 2 do not line up as in FIG. 2a , but touch with a more or large nip width B on a nip strip 4 or 5 according to Fig. 2b or c.
- the invention makes it possible for a symbolically represented in FIG Finishing plant 6 not only the crushing unit 7, but also the plant 6 as a whole extremely compact to build and sufficiently hysteresis-free or in the event of an emergency stop the machine to get the crusher setting almost instantaneously.
- the system according to the invention can squeeze the pressure, that is to say on the thread sheet 8 (general: the substrate) surface pressure, faster than speed proportional change and when comparing target and actual values the the amount of liquor 10 applied to the thread sheet 8, for example in the trough 9, is constant to regulate.
- the setting can be set to predetermined target values, for example in Dependence on the actual sizing recorded with the help of an order measuring device 15 (FIG. 2) respectively.
