Additional Features

Glue heads

The quickly replaceable glue heads are attached suspended over the product to be processed. An integrated distribution system distributes the material flow to various glue nozzles. From these, the heated adhesive flows out as beads in a regulated manner. The product is covered with 5 to max. 7 neighboring adhesive bead lines per glue head. The glue heads are attached to a transverse profile. There are three options for this:

  • Fixed: The individual glue heads can be freely positioned along the profile by slightly loosening the screw connections.
  • Oscillating: Another profile is attached on guide rails on a transverse profile on the lifting frame. The sliding bearing profile can be stimulated to oscillate via a servomotor with appropriate translation of rotary to translational movement. The glue heads are fixed to this. The individual heads can be freely positioned along the profile by slightly loosening the screw connections.
  • Movable: The glue heads are attached in a flexibly movable manner. Each glue head is equipped with a servomotor. Each head can be individually controlled and positioned via a rack and pinion system.

Bead application

  • Even bead application: The product is evenly covered in neighboring adhesive bead lines.
  • Intermittent bead application: The nozzles are closed and re-opened in defined time intervals so that a dotted bead line pattern is created on the surface to be glued.
  • Oscillating bead application: The glue heads of the surface application are laterally swung back and forth during the gluing process so that the glue is spread on the product in a sine curve pattern.
  • Variable number of bead lines: The glue heads are equipped with an additional valve which is electrically controlled. This enables you to switch on just some of the nozzles instead of the entire nozzle row in a glue head. The number of beads per application line can also be varied within one production cycle.

Adjustment to product dimensions

  • Automatic length, width, and height detection: The width of the sheet to be glued is automatically detected while gluing the front side by a sensor on the movable corner head. A sensor is attached to the conveyor belt in the glue tower to determine the length. The length is determined by the conveyor drive position monitoring. Successive varying sheet dimensions are possible in conjunction with the integrated height detection.
  • Programmable height and width adjustment: The dimensions of the sheet to be glued can be entered and saved via the control panel. As a result, sheets which cannot be reliably measured due to their geometry and/or surface texture can still be glued. In addition, the cycle time can be reduced by eliminating the measurement.

About us

The company Lamit has been a supplier of automated adhesive application systems and line design concepts for producing raw mattresses primarily for the mattress manufacturing industry since 1989. Lamit is a pioneer in the design and production of automated modular systems and line concepts for all common bonding processes in the mattress and foam processing industry.

In addition to specialized Lamit application systems for processing polyurethane adhesives for various foam products and this is just one example. Bäumer's Lamit bonding technology offers two different adhesive application processes for the mattress industry. Depending on the application and, in particular, on the mattress type, either water-based dispersion adhesives or hot-melt adhesives are used.

Albrecht Bäumer GmbH & Co. KG incorporated Lamit’s product range in 2015.
