While different cap types and sizes are seemingly unlimited, it requires a surprisingly low variety of capping machines to hide most of caps. Of course, unique and rare container tops may necessitate custom capping machinery. For many of us other caps, a little gang of capping machines will "seal" the sale.

SPINDLE CAPPERS. Spindle capping machines are the most popular capping machine produced for your packaging industry. These cappers use multiple matched discs to spin caps down onto bottles and other containers while they move across the capping area on a conveyor system. Normally, three or four sets of discs will probably be employed to gradually tighten caps. Elevators or vibratory bowls assist these continuous capping machines by delivering caps to each and every individual bottle, leaving the operator with the machine to merely replace bulk caps when needed. These capping machines are prepared for a wide range of screw type caps, including flat caps, sports caps, trigger sprayers and others. Numerous containers, including F-style containers (consider anti-freeze, a protracted narrow container using a handle), may be operate on the spindle capper and multiple containers require minimal changeover. The flexibility and simple operation are a couple of factors that produce this capping machine popular.

CHUCK CAPPERS. Chuck capping machines are like spindle cappers for the reason that they work with screw caps. Chuck cappers normally contain a metallic chuck as well as a rubber insert matched for the cap size. When a bottle is in place underneath the capping head, the chuck descends to make use of consistent torque to each bottle and cap combination. Automatic chuck cappers may include multiple chucks to increase the capping machine speed. Handheld, semi-automatic and tabletop chuck cappers will often cap one bottle at a time. While one chuck and chuck insert are equipped for different cap sizes, a facility running both minor and major caps might require multiple chucks and/or chuck inserts. Chuck cappers are best for flat caps, but a majority of modification for the chuck and inserts enable other screw type caps to become run too.

SNAP CAPPERS AND LID PRESSERS. Snap cappers and lid pressers are used for non-screw type tops. As an alternative to being torqued onto the bottle, snap type tops are merely applied using pressure and normally kept in place by a lip around the container. The pressure is used by way of a declined belt or perhaps a simple plunger with regards to the application. Paint cans may go well in the lid presser, while plastic containers for many food and beverage products would use a press on belt to avoid damaging the containers themselves. Snap cappers can be constructed much like spindle cappers, with all the spindle sets substituted with the decline belt, allowing snap caps to become sealed continuously also, caps permitting. Spindle cappers and snap cappers can even be combined on one capping machine to manage a level wider range of cap sizes and types.

Each of the capping machines discussed briefly above are available in different degrees of automation, allowing this group of packaging machines to take care of not only a wide variety of caps and bottles, but a range of production levels too.
