Equipment

Kraemer Koating designs and manufactures custom narrow web roll-to-roll web coating, web handling, and web processing equipment. In the simplest terms, we build equipment that can take a spool of continuous flexible material (such as paper, film, or foil), unwind it, and pass it through some sort of process.  Throughout this website, we will refer to this flexible material as a "web". As our name (Kraemer Koating) implies, part of the process usually involves applying some sort of coating to the web.  After a coating has been applied, the web can be conveyed through a dryer, a rinse tank, or any other web processing equipment that is required to to form the final product.

Coater / Dryer / Lamintors (C/D/L's)

While every machine we build is custom designed to satisfy the unique requirements of each customer, the closest we have come to a "standard" design is what we refer to generically as our Coater / Dryer / Laminator (C/D/L). Available in various sizes and and configurations, KK C/D/L's are used primarily in the pharmaceutical industry for the production of transdermal patches and oral dissolvable films. This same general design with a few modifications is also used in the battery industry.  

Our pharmaceutical C/D/L's typically  apply a solvent or water based coating to a plastic or polyester film.  This coating will contain an active ingredient and any supporting ingredients required to make the intended  product. The coated film is then conveyed through a dryer to remove moisture or solvent as needed to satisfy product requirements. After the dryer, the coated film may or may not be laminated by applying a backing film on top of the coating. After lamination, the coated film (possibly with an additional backing film) is conveyed to a rewind where it is wound as an intermediate product spool. The intermediate product spool is then processed by a pacakaging or pouching machine that unwinds the intermediate product spool, cuts pieces to the appropriate size and seals the final product in the required packaging material.

The production capacity of each C/D/L is determined by the width of the roll face (which determines the maximum coating width) and by the dryer length (which determines the maximum speed at which the machine can be run while still being able to dry the product sufficiently). Our standard CDL designs are for a (roll face) width of 12", 16", and 24" and dryer lengths of 12 feet, 16 feet, and 24 feet. However, we can provide custom widths and dryer lengths in cases where our standard sizes are not ideal for specific customer requirements. Below are some photos and descriptions of a few C/D/L's and other equipment we have designed and built.

Membrane Lines

Whereas our pharmaceutical and battery C/D/L's apply a coating to a web, pass it through a dryer, and possibly laminate it by applying a backing film before winding it as an intermediate product spool for further processing on other equipment, the production of membranes usually requires a very different process.

The membrane lines we have supplied typically convey a web (sometimes a non-woven fabric or some type of film) through one or more chemical baths and rinse tanks. After the web has been saturated or chemically treated as required, it is then heated in order to form (or cure) the membrane. Rather than a forced hot air dryer as we supply with our C/D/L's, our membrane lines usually include a series of heat tables. After the heat tables, the formed membranes are cut to the desired size. Below are some photos and descriptions of a few membrane lines we have designed and built.
