CORRUGATED BOARD INDUSTRY

Customer value

  • Increase product value by using low-cost end rolls
  • “Just-in-time” production of required paper width rolls
  • “No waste” by merging multiple small diameter rolls to full rolls

ONE-STEP PROCESS TO JOIN NARROW ROLLS

The E+L Skiver Line concept was developed to take advantage of cost savings realized by converting the low value end rolls into standard priced full width paper rolls. The end rolls are usually recycled in the paper mill, since they are under-sized for standard width production at the corrugator. Skiver lines can be installed in paper plants or corrugating plants.

The Skiver utilizes these undersized end rolls and skives a chamfer on the inside edge of both paper lanes, then glues both paper lanes into a full width paper roll. The skiving process eliminates the thickness change at the splicing point of both paper lanes. The Skiver can be run by only two operators. The operators have to feed the end rolls into the split web roll stand or two separate roll stands and unload the full rolls from the surface rewinder. While running, the operators should observe the grinders and glue unit.

  • End roll width 500 mm to 1,270 mm [20” to 50”]
  • Maximum line speed 300 m/min [1,000 fpm]
  • Maximum speed limited by split web roll stand

SKIVER LINE - STANDARD

  • Two roll stands, one for left paper path, one for right paper path

  • Full width option to run full width roll for printing, coating or joining small rolls to usable large diameter rolls
  • Space for additional coater or printer integration; requires the full width option
  • Video system to display all process-relevant sections on large screen monitor at main control station
  • ELCLEAN vacuum cleaning system to remove all dust and contamination from top and bottom surface
  • Slitter at rewinder to trim edges to desired width
  • Large-screen production display
  • Integration into customer labeling and/or roll reporting system

ROLL STAND

Roll stand with split web functionality. Two end rolls can be loaded onto the roll stand and fed into the Skiver Line. Including automatic splice and tension control system.

GUIDING SYSTEM

E+L guiding systems (left, right) guide the narrow paper webs into the skiver stations to ensure a consistent chamfer on the paper edge.                                                                                           

GRINDING

The center edges of the left and right paper webs are skived and a chamfer is ground. This chamfer will allow the splicing of the two paper webs without thickness change in the paper.


GLUE UNIT

Glue is applied to one of the paper web, which is spliced together with the second web.                                                                                                                                                                              

REWINDER

The surface rewinder winds the skived paper to a usable, full width paper roll. A kick-out mechanism moves the roll to the adjacent J-table and lowers it to the floor.                                                       

TENSION MEASURMENT

Load cells are incorporated into the guiding systems to measure the tension of the left and right paper. The tension is displayed on the operator station.                                                                          


DUST VACUUM SYSTEM

Dust vacuum cleaning system eliminates any residual dust from the skivers or slitting unit. The dust is deposited into a bin at the filter-fan unit.                                                                                

SLITTER

A slitting system is included to trim both sides of the paper to the desired width. This will also ensure a perfectly wound roll at the rewind stand.                                                                                       

VIDEO SYSTEM

Cameras can be added to display the roll stands, grinding (left / right), gluing process and rewinder on a large screen monitor at the operator control station.                                                                    


FULL WIDTH OPTION

Full paper width can be run through the Skiver Line, bypassing the grinding and gluing section. This option can be used to splice multiple short rolls into one large roll.                                                  

INTERFACE

E+L offers the interface development to customer inventory control software for keeping track of used end rolls and skived full width rolls.                                                                                                  

COATER INTEGRATION

A full width coater (customer supplied) can be installed in front of the rewinder, allowing the coating of full width paper.
