Cap Lining Machine

Lining machine

Our industry standard cap lining machine inserts induction wadding/liners into caps from coil liners or pre-cut liners. Among various types of cap lining machines, we have different models of machines that are suitable for each production need, such as: Cutting Power, Production Speed, Cap Sizes and Shapes.

This cap liner machine is equipped with inlayer and cap wadding fixer. The caps will be stacked in a vibratory, rotary or hopper hopper physically stacked. The feeder supplies the caps satisfactorily as required to the machine in the style arranged. The conveyor moves the caps to a star wheel where the caps are filed into predefined zones. 

The bundles are stacked into a column hopper (if in rolls) or a vibratory feeder (for loose liners, typically for EPE or foam liners) which is positioned above the bundle pick-up station.

A vacuum loading machine is placed below the section hopper, which picks up the wad individually and places it on the upper segment of the ordering star wheel above the plugs. At the moment when the cap and the block are moved to the next station, a pusher inserts the block into the cap and it is fixed immovably. 

The collected cap will be counted and will exit the conveyor. The cap lining machine will be suitable for taking care of different types and sizes of caps and bundles with the help of progress parts.

Note- Cap Wadding Machine, Wad Inserting Machine, Cap Liner Machine and Liner Inserting Machine etc are the same terms.

  • Pre-cut cap wadding process

Depending on the finish/cap design we can choose from our variety of cap feeders and cap moving belts. The fundamental principle of our standard liner insertion machines is to use a rotary indexer equipped with a star wheel to obtain caps and terminations in one or several paths depending on the company’s creation needs. 

Each plug is inserted into an individual cavity of the star wheel to maintain zone security as it travels through the machine.

We have planned and built several stations of bundle inserting machine with single head, double head and quadruple head. These heads use vacuum to pick up and place the pre-cut liners/cartons from a magazine into the cap. 

Each of our machines can be used for both induction and EP liner insertion. To enhance product quality, we have some additional features of discretionary value.

  • Roll-fed stopper wadding process

The machine is set up to cut the roll-fed liners and insert and fix them into the plugs in one operation. The plugs will be physically stacked in a vibratory garbage can or elevator hopper. The feeder supplies the caps in sufficient quantity to the machine in the design positioned. The conveyor moves the cap to a dial where the caps are filed in predefined areas.

Liners on rolls are placed on the feed rollers and cut off just before the punching station. The liner falls into the plug and when the plug and block move to the next station, a pusher inserts the block into the plug and it is immovably fixed. 

The collected cap will be checked and exits the conveyor. The machine is equipped to process different types and sizes of closures and bundles with the help of progressive parts.

The caps are fed into the container in large quantities and transported to the elevator, which in turn transports them to the unscrambler. This unscrambler rotates at high speed and transports the caps to the infeed conveyor. 

Before passing to the infeed conveyor, the inverted caps are removed and the caps with the cavity upwards pass through the infeed conveyor to the cap ordering mechanism. While the caps are being filed, the lining machine are punched and inserted into the caps using a punch and plunger system.

The bundles are fed into rolls and, for each register, punched and inserted into the plugs depending on the production rate, a 1up, 2up and 3up punching configuration can be chosen. 

Since the production rate is high, the plugs are collected in a rotating collector before entering the conveyor, so that the plugs are conveyed to a conveyor belt at a constant rate. 

When the caps are embedded with the bundles, they exit through an end conveyor and are collected in a collection garbage can. The production rate of the machines is 150 – 500 closures per minute.
