Where we help in the production of healthcare and hygiene products

Gluing elastic elements in diapers and incontinence products

Precise spiral or bead application of hot melt to fix elastic strands, cuffs and leg hems in disposable diapers and incontinence products. The instant setting of the adhesive keeps up the production pace on a high-speed line.

Lamination of nonwoven layers

Coating or spiral application of hot melt to bond the top sheet, the core layer and the back sheet of hygiene products. An even, thin layer of adhesive ensures the cohesion of the structure with no overflow onto the product surface.

Production of surgical masks and protective clothing

Needle-free bonding of nonwoven layers for surgical masks, disposable surgical gowns and protective covers – with no needle holes that could be a source of contamination.

Fixing the absorbent core

Precise dosing of hot melt to stabilise the absorbent core inside a hygiene product – no movement of the core when worn, no adhesive overflow onto the product surface in skin contact.

Production of filters and respirators

Gluing layers of filter media and the structural frames of disposable respirators and face masks. Hot melt ensures a firm bond even with delicate filter materials without damaging their structure.

Layering of tissues and hygiene paper

Bonding layers of cellulose and nonwovens in the production of paper tissues, napkins and hygiene paper. Spiral or coating application of hot melt ensures a cohesive multi-layer structure with no adhesive on the product surface.

What you're dealing with

  • Production lines for hygiene products (diapers, sanitary pads) run at high speeds – the application system has to dose the adhesive precisely and repeatably even at a high cycle rate, with no adhesive stringing or dripping that would contaminate the product surface.
  • The products come into direct skin contact – any overflow or contamination from the gluing process is unacceptable. A precise cut-off and a clean application with no adhesive stringing are key hygiene requirements for the application system.
  • Different materials, different layer thicknesses and different types of products require different adhesive-application configurations. Switching between products has to be fast and with no loss of application quality.

How Kaletech solves it

Robatech systems for the production of hygiene and healthcare products deliver a precise, clean application of hot melt – with no adhesive stringing, dripping or overflow onto the product surface. Whether it is spiral spray for laminating layers of nonwovens, precise dot dosing for fixing elastic elements or a bead application for fixing the absorbent core, each configuration is designed for the specific parameters of the line and the type of product.

A key property of Robatech application systems for hygiene is a reproducible application even at high production speeds. Electric application heads switch the adhesive in milliseconds – the start and end of application precisely follows the signal from the line PLC, so the adhesive is where it should be and nowhere else. The result is a clean product, minimal adhesive consumption and no cleaning of overflow.

How it works and what technology is used

Robatech technology for healthcare and the production of hygiene products works exclusively with hot melt technology – a solvent-free adhesive applied hot that sets instantly with no need for a drying zone. This is a key prerequisite for high-speed production and a clean process in skin contact. The Robatech system integrates a melter, a heated Performa hose and an application head into a controlled unit synchronised with the production line. The choice of the specific application head (spiral spray, dot dosing, bead) depends on the type of application and material.

  1. Hot melt preparation and melting

    A compact melter (Alpha for lower adhesive consumption, MultiMelt for high-output lines) melts hot melt granules to a defined viscosity. Stable temperature and pressure are the prerequisite for a repeatable application – every product receives the same amount of adhesive.

  2. Adhesive transfer through a heated hose

    The heated Performa hose maintains a stable temperature and viscosity of the adhesive from the melter all the way to the application head – with no temperature fluctuations that would cause an unstable application or adhesive stringing.

  3. Precise application by the application head

    The electric Volta or SpeedStar Compact heads switch the adhesive in milliseconds – a precise start and stop responds to the signal from the line PLC. Spiral spray is used for laminating layers of nonwovens; dot or bead dosing for fixing elastic elements and the absorbent core.

  4. Synchronisation with the line and monitoring

    The RCS control system or direct integration via PLC synchronises the application with the movement of the material. Real-time monitoring of adhesive consumption alerts the operators to a deviation from the norm – even before a defective product leaves the line.

„To seal the filters of a respiratory half-mask we approached Kaletech, which helped supply both the technology and the adhesive. Given the time constraints we chose a solution with collaborative robots and also used the rental service, which sped up production even before purchasing the technology. We are satisfied with Kaletech's services and products and will gladly recommend them for another project."
