Definitions
- the present invention relates to a method of automatically feeding a separate wrapper around a web-like product, for example a paper web being reeled in connection with a slitter-winder, and to an apparatus for practicing this method.
- a separate wrapper is formed onto the surface of the reel for example as follows.
- the slitter-winder stops automatically at this amount.
- the operators of the machine apply a precut wrapper onto the surface of the reel being completed and tape it onto the paper.
- the slitter- winder is started again at a creep speed of 15 m/min and the wrapper is run at this speed onto the surface of the completed reel.
- a purpose of the invention is to eliminate the above-mentioned disadvantages and to provide an improved method and apparatus for feeding a separate wrapper.
- a wrapper is applied onto the surface of a reel being completed, e.g. a paper reel, in connection with the normal functions of a machine, e.g. a slitter-winder, so that no halts restraining the production occur.
- the wrapper is wrapped around the reel being completed so that the wrapper + the web being completed move the whole time during the wrapping of the wrapper.
- the wrapper is wrapped around the reel being completed without having to stop the reel being completed or the web being reeled at the same time.
- the web being reeled is not stopped until the reel is complete and a wrapper has been wrapped around it.
- Figure 1 illustrates side view of a wrapper feeding apparatus
- FIG. 1 illustrates section A-A of the wrapper feeding apparatus in Figure 1.
- Figure 1 illustrates side view of a wrapper feeding apparatus and Figure 2 illustrates section A-A of the wrapper feeding apparatus in Figure 1.
- Reference number 1 depicts a feed nip I comprising rolls 11 and 12, which feed nip I pulls and adjusts the wrapping of a wrapper web 10 from the stock reel to the wrapper apparatus.
- Reference number 2 depicts a feed nip II in which a roll 20 positioned against a spring-loaded strip 21 keeps the wrapper tight between the nips 1 and 2, whereby it is possible to cut the wrapper web in a controlled way.
- a cutter 3 has a stationary lower blade 31 and a rotating disc blade 32 attached to a shuttle cylinder, which disc blade, while moving, cuts the wrapper perpendicularly to the web.
- a transfer cylinder 41 which is driven by compressed air, moves a connecting roll 4 against a lower paper guide roll 70 to form a connecting nip.
- the lower paper guide roll of the slitter-winder is marked with reference number 70 and the upper paper guide roll with reference number 71.
- Reference number 5 depicts a toothed belt system used for rotating the connecting roll nips I and II.
- An inverter 6 guides an electric motor 61, which then rotates the rolls.
- Guide and supporting planes used in the feeding of the wrapper are marked with reference number 8.
- the wrapper 10 moves on top of these guide and supporting planes 8.
- the web being reeled is marked with reference number 50.
- the normal production rate of a slitter- winder is approx. 1800 m/min.
- a decelerating run begins during which the speed of the web 50 being reeled decreases to about 15 m/min.
- the change of the speed of the web 50 being treated on the slitter- winder and the reaching of the predetermined amount give the wrapper feeding apparatus the required guidance. Changes in the above-mentioned factors then activate the wrapper feeding apparatus in a preprogrammed way.
- the speed of the slitter-winder has decreased to an appropriate speed, e.g.
- the connecting roll 4 rises up forming a roll nip against the guide roll of the slitter- winder.
- the connecting roll 4 in top position is depicted by a broken line and reference number 4'.
- the uppermost roll 4 of the wrapper feeding apparatus rises up into contact with the paper guide roll of the machine and the wrapper feeding apparatus starts to feed the wrapper.
- the wrapper device is activated and the forward edge of the wrapper passes through the connecting nip.
- the forward edge of the wrapper is provided with a pre-adjusted two-sided adhesive tape, which as the wrapper passes through said nip, adheres to the paper web and affixes the wrapper to the paper web.
- the wrapper feeding apparatus may be stopped while the paper web still moves forward normally. However, the tension of the web being rolled stays the same during the entire run.
- the wrapper web cutter 3 cuts the wrapper perpendicularly to the web. After the cutting the feed nips of the wrapper feeding apparatus are re-engaged and the tail of the wrapper is run out of the apparatus and the forward edge of a new wrapper is positioned in stand-by position for the adjustment of a forward edge adhesive tape for the next run and the feeding device stops.
- the slitter- winder continues to operate at creep speed until the tail of the wrapper fed is on the surface of the completed reel and the slitter-winder stops for the removal of the reels.
- the completed reel is changed as usual i.e. the machine stops, the paper web is cut, the tail of the wrapper is affixed with adhesive tape to the surface of the reel and the reel is removed from the machine and replaced with a new core.
- the reel being completed stops only once during a run and that too takes place when the completed reel wrapped in a separate wrapper is removed from the slitter- winder.
- Inverter motors are used to adjust both the reeling speed of a web-like product, e.g. paper web, and the feeding speed of the wrapper.
- the wrapper feeding apparatus is guided by the change of the speed of the web 50 being treated on the slitter- winder and by the reaching of the predetermined amount, whereby it is activated.
- the inverter motor makes it possible to accurately and steplessly adjust the feeding speed of the wrapper and, in a run taking place in various speed ranges, to produce loose paper web "in a controlled way" for the cutting of the wrapper, although the paper web itself and the wrapper along with it advance uninterruptedly.
- the paper web itself and the wrapper along with it advance during the entire action of wrapping into a wrapper at a steady speed, e.g. 15 m/min, towards the reel being completed.
- the web being completed moves during the wrapping into a wrapper at a speed considerably slower than 50 m/min, preferably in the range 1 - 30 m/min and particularly preferably in the range of about 5 - 20 m/min.
- a length counter in the machine monitors the length of the web of the reel being completed and that of the web leaving the stock reel. The stops of the machine are based on this counting.
- both the forward end and the tail of the wrapper being formed around the reel being completed may be glued onto the paper web being reeled itself. This ensures that the wrapper stays well in place for example during subsequent packing and transport. If the forward end of the wrapper being formed around the reel being completed were just tucked between the paper turns, i.e. the forward end of the wrapper were not glued onto the paper web itself and only the tail were glued onto the paper web being reeled, the result would be a packing with a poor tolerance of handling.
- the normal production rate of a slitter- winder is approx. 1800 m/min.
- the machine operates at a speed of about 1000 m/min, after which the speed rises to the normal production rate.
