application example


The Steel Stripper Ring System

Using steel stripper rings is a method to put pressure onto the strips. Hence, the strip is guided and ejected.This system is commonly used for very thin materials, because bonded stripper rings having a width of lessthan 2,5 mm do not offer the required stability to effectively guide and eject the slit material.Steel stripper rings do not get placed directly onto the knife arbors. They are running against pressure rollerbars and their centreline is offset from the centreline of the knives and spacers. This system allows simpleadjustments according to the material thicknesses to be slit by means of adjusting the pressure roller bars.

The setup of steel stripper rings has to be adjusted exactly in accordance to the slitting application.will gladly offer advise and assistance in helping to achieve the best possible result.Neuenkamp

The pressure equalizing ringallows for an equal pressure distributionof all axial clamping forces along theslitter tooling arbors.

Neuenkamp

Pressure Equalizing Ring

The equalizing ring absorbs uneven clamping forces on one sideand transfers the clamping forces equally and preciseonto each pressure point of the ring and then against the ultra precisionsetup. As a result possible axial runout conditions of the tooling will be drasticallyimproved.Slitting processes, which do require extremely accurate axial runout conditions,as well as the ever increasing number of strips slit on one head, were the basis forthis new design by .Neuenkamp

Neuenkamp offers a computer-assisted service tooptimize the amount of tooling required for yourindividual application.The quantities and thicknesses as well as the total-amount of the required tooling is calculated by the system.The basis for the precise calculation for your data is:

The resulting calculation will guarantee a 100% coverageof all tooling needed for all required slit widths.Because of the mathematical basis of the toolingoptimization, considerable cost savings are achievedcompared to conventional methods.The tooling sizes calculated by using this method aredimensioned so that plastic shims are no longer needed.By feeding in different operational data, we can calculateyour tool requirements for all current slitting performances.By doing so, we can show you an additional andconsiderable cost advantage.By means of the mathematical statistics in our system,we work out the tooling that your really require.

Our tooling assembly software is a computer software program especially developed for the easy andaccurate calculation of the tooling assemblies of the slitter arbor setups as well as the various separator shafts,such as the overarm separator shaft, tension shaft and loop doubler shaft.It offers an easy and comfortable working environment under the Windows Operating system, utilizingWINDOWS 2000™ version or higher.The program offers tooling setups in various printout versions, for instance a chart or a full scalegraphic printout. Setups are generated by entering all necessary data for a particular slitting operation allowingthe program to calculate the required tooling to be used and to build the printout of the slitter arbors andseparator shafts. Completed setups with their corresponding data can be saved under a file name and called upwhen needed. This feature is extremely helpful in case of repeat orders or new setups which require only minorchanges to achieve a new setup.A possible link of the program to existing customer systems will be evaluated by our softwarespecialists at the customer's site. The necessary integration will be programmed by our software personnel.

Economically and consistently providesa mirror-like finish on rotary slitting knives,achieving a better quality cut andextended knife life.Typically, companies slitting aluminium,brass, copper and other soft metalsexperience a knife edge build-up whichprogressively and adversely affects theknife's cutting abilities and its dimensionalcharacteristics. This automatic polisherrestores the fine edge with no realchange in the thickness of the originalblade.

Accessories

Tool Storage SystemsOffers increased flexibility in storing slittertooling. Protects tooling from possibledamage and decreases possible dirtbuildup, ease of tooling handling, reducingthe setup times resulting in increasedproductivity. The compact tool storagesystems offer sufficient space for thetooling, PC work station and additionalstorage areas for setup accessories, withminimal floor space requirements in mind.Individually tailored to meet the customer'srequirement in terms of the toolinginventory and floor space availability.

Hydraulic NutsApplied to obtain a defined and uniformclamping pressure, necessary to locktooling properly onto the slitter arbors.Reduced setup times, due to an easy andquick locking and unlocking mechanism.Improved tooling placement accuracyduring the clamping process, based uponan equal axial pressure distribution,causing a decrease in vibration, a balan-ced setup and minimizes the hazardsusually involved with manual clamping nuts.Hydraulic clamping nuts can be usedcommonly in all slitting lines.

Plastic ShimsMade of special hard plastic,oil and grease resistant, moisture andwater repellent, good wear resistanceand thickness variations when placedunder pressure.Handling and identification made easydue to a colour code.Width from 0,012 mm to 1,5 mm.
