Surprisingly, you may find only a few types of capping machines in the packaging industry to cover different types and sizes of caps. Of course, these machines are custom-made in nature to meet the requirement of unique and rare container tops. However, the question is – how can a low number of machines justifies seemingly unlimited caps? In this article, you will get to know about some common types of capping machines that can indeed ‘seal’ the deal for almost all types of caps.
Spindle cappers are the most common and also the most popular types of capping machines. To spin the caps down onto the bottles, these cappers use a set of matched discs. Usually, a set of three or four discs is used to tighten caps. To assist these machines, vibratory bowls are used. They simply deliver caps to the bottles. This is the reason that these machines can accommodate a wide range of screw type caps, including sports caps, flat caps, trigger sprayers, etc.
Chuck cappers are similar to spindle cappers, as they are also ideal for screw caps. Two major parts used in chuck cappers include a metal chuck and a rubber that is inserted to match the cap size. Once the bottle is placed under the capping head, then the chuck starts descending to apply torque to the bottle and its cap. To increase the speed of the machine, multiple chucks can be added. Chuck cappers are considered ideal mainly for flat caps, however, some modifications can make these machines worth looking for even for screw type caps.
Snap Cappers And Lid Pressers
Snap cappers and lid pressers are ideal for non-screw type tops. Instead of being torqued onto the containers or bottles, snap type tops are applied with pressure and usually held in the right place using a lip. To apply pressure declined belt or simply a plunger is used. Unlike paint cans, plastic containers for food and beverage products use a press on their belts in order avoid damaging the containers. Interestingly, snap cappers can be combined with spindle cappers on one capping machine to accommodate even a wider range of caps.
ROPP Capper, short for Roll On Pilfer Proof Capper, uses specially designed knives in order to thread and seal the tops onto the bottles or containers. A bottle of wine would be the perfect example, when it comes to the products that can be accommodated by this machine. To get the job done perfectly, different bottles or containers require different sets of knives.
