Ceramic ball bearings are fully resistant to corrosion as both the external and internal races are made of stainless steel, while the inner cage is made of plastic material, which is resistant against high temperatures. Thanks to the low friction of the ceramic balls, the seaming rolls require a reduced lubrication – up to five times less than standards. This saves time for the operators and the machine downtime, allowing increased production.

Thanks to our experience in this industry, Imeta has developed new assemblies for some older seaming rolls. These include the “Easy System” type roll for the Angelus P Series, and the “Super Seal” type roll for any seaming machines. These can reduce roll maintenance time and costs.

In addition to the bare rolls, Imeta offers – as an optional service – the seaming rolls preassembled with their pins and bearings. Seaming rolls are then provided already set and lubricated, ready to be mounted, allowing significantly shortened machine downtimes. The assembly is carried out by our skilled technicians using all the correct tools and equipment such as the hydraulic press and the dynamometric wrench. Potentially using certain old items (pins, bottom plates, dust covers), that maybe still in good condition, it is also possible to provide partial assemblies according to the client’s needs.

Depending on the client’s needs, seaming chuck lips can be provided with the following superficial finishing features smooth, sandblasted or knurled.

Ceramic seaming rolls can increase production efficiencies and reduce machine downtimes by eliminating or significantly reducing many problems deriving from wear, corrosion and superficial damage. There is a low friction coefficient and they are approved by the USFDA.

UCAR plating is applied on the lips of the seaming chucks in order to offer high wear resistance features, besides friction with the parts it is in contact with.

This chromium plating is used for some applications, such as seaming rolls for filters and deepdrawn aluminum cans. It guarantees a very good wear resistance and a low friction coefficient.

This coating is typically applied on seaming chucks and rolls and it extends their life up to three times. Surfaces coated with DIAMOND 98HRC have a very low friction coefficient, and as a consequence they have very high anti pickup features. Therefore, rubbing is reduced, and seams can avoid peeling.

PVD coating is commonly used on seaming chucks made of steel.

CVD coating is typically used for Stoody seaming rolls and chucks. Its main feature is its superior adhesion to the base steel, which provides a high resistance against wear and corrosion.

Seaming chucks and rolls made from tool steel are generally considered the industry standard for can factories, while canneries generally use stainless steel. Other types of steel are commonly used in the production of seaming chucks for Easy open covers, especially for those chucks that suffer from a weak chuck lip.

Imeta is specialized in overhauling seaming machines, filling machines as well as can and cover manufacturing machines of any model. Our Exchange Program allows the clients not to interrupt production while we prepare an overhauled machine. All overhauled machines are sold with a oneyear guarantee and an integrated user manual. They meet the requirements of the CE Standard and/or other standards the Client may require. Depending on the model, the following features can be upgraded with various optional extras. The following pages show some examples of our fully overhauled machines. If you have any questions, please ask our Trade Office.

Thanks to the Inverter group it is possible to remove the entire mechanic clutch group, that has over 30 different part numbers (50 items). This upgrade also has the advantage of bringing significant savings during the maintenance phase, not just as regards the items that are removed, but also in terms of the gears, pins and bearings, since “softer” operations will prolong their productive lifetimes.

The “DESMO” Kit for Angelus 60 L includes A desmodromic cam that controls both opening and closing of roll levers at any speed A desmodromic cam that guarantees the return of the extractor shafts at any working speed A series of seaming levers allowing the adjustment of seaming rolls and very fast changeover with no need of dismantling the levers.

This conversion kit consists of six larger driven lifters, a pair of stainless steel turrets with upper splined hubs, and a rugged central splined shaft. There is also a range of optional extras that can be provided with the Gear Driven Lower Lifters in order to further improve their performance.

Whereas necessary, all the cover feeders can include a pneumatic lid gapper (“No CanNo Cover”) in order to reduce the load on the feeding screws.

Imeta has also developed Cover Feeders that can feed aerosol tops and bottoms and special components such as varnish rings or deepdrawn covers, as well as a wide range of special feeders with three or four screws for rectangular or oval covers.

This feeder was initially designed for installation on the Angelus 60 L and was then adapted for many other machines. The innovative feature here is that the feeding screw is inclined and parallel to the cover stack, making the feeding more natural and fluid. This feeder is adjustable and, with the substitution of just a few parts, it is suitable for any cover diameter (between 50 and 105mm).

Imeta provides complete changeover kits for single and multistation Cevolani machines, depending on the type of can required by the Client. The standard kit includes design and manufacturing of all necessary tools, such as rollers and knives for parting stations, rollers and formers for beading stations, complete spin flanging heads, complete necking heads and seamer changeover parts.

Imeta provides complete changeover parts for Lanico flanging, necking and seaming machines, for any type of can a customer may be running. The standard kit includes base plates, seaming chucks and seaming rolls with coatings, in order to offer a longer productive lifetime. Partial changeover kits can be provided if, for example, straight cans need to be necked.

The 60L seaming machine is a multifunctional machine that meets the most diverse manufacturing needs, from cans for food or drinks, to canmaking, aerosols, composite cans and general line cans. Imeta has the necessary knowhow to transform and equip such a machine depending on different can and cover specifications, even beyond the original standard set up.
