Therefore, the use in the cooling stage allows a significant reduction in the curing time of the product, as well as making the process manageable and controllable. When the suppository mass in the cooling unit is fully cured, the spool with the finished product is transferred to an automatic container sealing and ribbon cutting machine. In the machine, the ribbon is sealed and cut into sections with the specified number of cells. Sealing is carried out by pulse heating and compression. The stable temperature of the sealing tool is ensured by two high-power fans. Simultaneously with sealing the coding operation is carried out. Coding of containers (series and date) is carried out by extrusion by means of a cliché. After sealing, the edges of the tape are automatically processed. This operation allows to significantly improve the appearance of the finished product. To control the process of cutting the tape into strips of a given length, a digital programmer is used, which sets the cutting range from 1 to 10 suppositories. The machines allow the production of suppositories in contoured cell packs made of aluminum and thermoformed plastic. In contrast to medium-capacity production, in the high-capacity industrial machines, the molding of the contour cells is done directly in the machine. High-precision machine with low noise level and high productivity (up to 22 thousand suppositories per hour). The machine is controlled through a programmable logic controller (PLC). The automatic machine has an optimal mode of operation, which avoids the formation of waste in the production process. The production process of suppositories begins with the formation of contoured cell packaging made of plastic film or aluminum foil. Two rolls of plastic film (one roll – printed, from which the front part of the suppository package is molded, the second roll – unprinted) are installed on roll holders. Plastic films from both rolls simultaneously enter the pre-heating unit, where they are quickly heated to the required temperature. The required film tension is regulated by a special device. The preheated plastic films are fed to the contour cell-shaped plastic film heat-welding unit.

In this way, the two films are joined together over the entire surface, except for the interior of the cells. Then the film enters the molding unit, where, by blowing compressed air into the unsoldered space, the contoured cell is volumetrically molded. At the same time, a small hole remains open in the upper part of each cell, through which the cell is subsequently filled with suppository mass. In case of aluminum foil packaging production, the contour cell forming unit dismantles the units designed to work with plastic film – film preheating unit, film heat-welding unit and forming unit. The aluminum foil cell forming unit is installed in their place. Due to its heavy weight, this unit is installed in the machine by means of a lifting mechanism. It should be noted that the units are common for both types of packaging. Two rolls of aluminum foil (one printed and one unprinted) are installed on the roll holders. The foil tension is adjusted by the device. The aluminum foil strips from both rolls are fed in parallel to the contour cell forming unit, where the contour of the cell is mechanically extruded on the surface of the aluminum foil strip. Thus, in contrast to plastic foil, no preheating or compressed air is required for forming cells from aluminum foil. Two unconnected ribbons with the molded halves of the contoured cells exit the forming unit. The two strips are then joined together so that the cell halves are completely overlapping and are fed into the assembly where the strips are heated and finally thermally welded together. At the same time, as in the case of the plastic film, an opening is left open at the top of each cell for the introduction of the suppository mass. In this way, the contour cell formed of plastic film or aluminum foil serves at the same time as an injection mold. The plastic or aluminum foil-formed package is fed into the filling unit in the form of a ribbon. The suppository mass, heated to a temperature of 30-80 ° C, depending on the active ingredient and base from the reservoir comes through a pipeline to the volumetric dispenser, from where the product is automatically loaded into the cells.
To maintain the required temperature and homogeneous consistency of the suppository mass, the 80-liter reservoir is equipped with a water jacket and a stirrer. In the production of glycerin-based suppositories with a viscous consistency (they are usually molded in aluminum foil), the agitator provides homogeneous mixing of the suppository mass, heated to a temperature of about 80 ° C.
