Abstract
The invention relates to an apparatus and a method for the completely automatic lacquering of strip-form materials, whereby at least one unwinding device is provided with a fast running positioning device, an application roller and an opposing pressure roller are designed in such a way that they grasp the strip-form material and push it centered through the dryer and through a guide device and a winding up device is provided with at least one receiving spool which catches the strip-form material and winds it up.
Claims10
In an apparatus for strip-form material preparation by automatic initiation of lacquering of a surface of a strip of rollable material comprised of paper or film and subsequent drying
- the combination of
- an unwinding strip feed device,
- an application device for applying said lacquer,
- a dryer,
- and at least one winding-up device wherein said application device comprises
- an application roller and an opposing pressure roller
- means for holding said rollers in a separated position and thereby provide an opening for insertion of a leading end of said strip,
- means for insertion of said leading end into the application device and the opening to actuate a first control downstream of the rollers for the application of the lacquer,
- means actuated by said first control for initiating application of said lacquer to said strip by moving said rollers toward each other in contact with the strip,
- and whereby the rollers in contacting the strip grasp the strip and move it centered through said dryer and a guide device to winding up on a receiving spool in the windingup device.
A method for automatic initiation of lacquering of strip-form materials comprising the steps of
- feeding a strip of material into a lacquer application device,
- inserting the leading end of the strip between a lacquer application roller and a pressure roller, said rollers being spaced apart in said application device
- actuating a lacquer initiating signal with said leading end to operate means moving said rollers together and applying lacquer to said strip surface and grasping said strip between said rollers and guiding the strip to drying and curing in a drier
- and then feeding the lacquered strip to a strip receiving spool and winding the strip in a roll on the spool.
