Lack of adjustment press corrugating roll group GO-14 (Agnati) with low basis weight papers, starting the boot after an extended shutdown and low speed. Contact lines are excessively marked paper cover reaching breaking paper (F-1 and F-4).
Cause: A minimum starting speed, the press roller tends to expand a few thousandths due to the thermodynamic effect, this requires a separate roll through stops, otherwise the cover paper suffers irreversible damage. Some groups have built-crimping load cell, which make the adjustment automatically and programmed in function of the velocity curves (Prometheus control process or similar)
3 -. Through the operator to perform physical check and then fine-tune the roller press the buttons on the desk (+ and -), (F-2). At low speed to separate the grooved roller press roller, and increase the speed gradually adjust to the correct position paste, or unlabeled break the surface of the cover paper.
Speed: Depending on the speed variations, buffet warming trays the roller press must separate or come through the stops (F-6) on the upper corrugated roller, making sure the paper does not get covered or cut or peeled off at the point of impact (nip-3 F-4 and F) of the two papers and casing buffet warming trays cover.
Since the yield more heat on the papers, the rollers tend to shrink a few thousandths development, leaving the ends of the two papers to the body outlet for separated buffet warming trays or detached nonunion including corrugated.
By slowing occurs in reverse, the rollers so dilated that the press roller must be separated by bumpers, otherwise the cover part suffers permanent damage. Some groups have built-crimping load cell, which make the adjustment automatically and programmed buffet warming trays wave velocity function
Weight or thickness of the paper: A thicker heavier weight buffet warming trays papers (must separate the press roller). In this case you have to adjust bumpers roller buffet warming trays press, without reaching across the line of contact between the two papers. If I had cut in the contact line can be detected, making a manual control over the paper cover and the paper gut damaged fiber is observed. A lighter weight less thick papers (must bring the press roller).
Width change roles: buffet warming trays Due to the difference of the grooved pump and roll press rollers, in production and in short intervals, it is recommended the operator's body curl, perform visual and physical checks manually. Checking each end of the single buffet warming trays face to the departure of the curl, the two roles, and joined buffet warming trays together, do not show lines cut lightly contact or separated (taken off) (F-5).
Influence of temperature: The temperature is a thermodynamic actually influencing the diameter of the rollers. The following table and accompanying formula is to calculate the dimensional buffet warming trays change, buffet warming trays suffering the rollers according to different temperatures. The steam changes its temperature depending on the pressure, according to the following Table (T-1).
Obviously the absolute temperature of the roll is lower than the steam function of various parameters: speed, paper weight, wave profile, type of steam installation, inverter type group (positive pressure, vacuum, etc ...) type grooved rollers, roller press type or similar, buffet warming trays applying glue, etc ... Practically buffet warming trays varies from group to group and is not calculable.
diameter. T = x diameter. x KT diameter. = Change in external diameter. (Mm) T = Change in temperature of the steam. ( C) KT = coefficient of thermal expansion of steel = 0.000012 Therefore, for a Agnati S-90 between 15 and 10 bar: diameter. = (197.36 C - 179.04 C) x 360 x 0.000012 = 0.079 mm.
As you can appreciate the variations are small, but undoubtedly buffet warming trays affect adjustment (fine adjustment) between the central grooved roller with roller pre
