Wrapping of jellies
The jelly candy wrapping techniques employed by Carle & Montanari’s wrapping machines have long been a source of pride and one of our greatest successes. Over the years we have invested much time and effort in the continuous search for the best solution to guarantee higher wrapping speeds without compromising the delicate handling operations required by this product. The aim is to obtain top quality wrappings without having to wait for long setting times and risk losing the typical soft consistency of these products.
Our belief in this philosophy, which was successfully put to the test, in the field, with the original CMY55-J machine (still the best choice for medium-sized production runs using "double twist" style wrapping), has led us to push towards achieving higher production rates of up to more than 800 wraps/min. with the CMY871-J machine.
We shall now take a closer look at how the product is handled:
The air blown to the disk feed system is kept at a controlled pressure in order to properly fill the cavities. All the subsequent transfer devices, such as the counter-elevator and the grippers of the wrapping turntable, are provided with spring-back restraining devices thus preventing the product from being permanently deformed in any way.
Particular care is given to making the “twists” thanks to a device which holds the product firmly between two grippers in order to effectively counter-act the torsion the product is subjected to because of its softness.
The result is a wrapping with perfectly executed “twists” containing a non-deformed product. Four machine models are available for wrapping "double twist" style jellies in order to cater for different customer requirements. These are as follows:

• CU954-J (300 wraps/min.) · CMY55-J (450 wraps/min.)
• CMY800-J (700 wraps/min.) · CMY871-J (800 wraps/min.)

Although the double twist shape wrapping is perhaps the most commonly used by sweet manufacturers, Carle & Montanari also offers the so-called "open points" shape with the CMY55PA-J version wrapping machine. The latter can reach the same speed and use the same feed unit as the CMY55 "double twist" machine but is also provided with a special folding unit to create a completely different wrapping shape using the same gentle handling techniques.

Book moulded products
The growing demand for “bonded” products such as eggs, hollow figures with surprise gifts, etc. has led to the development of a simple and reliable device for coupling two symmetrical moulds very quickly.
The system executes a “book-like” coupling operation to bring the two moulds together by moving them simultaneously up into a vertical position in which the two moulds match perfectly.
At this stage the coupled moulds are rotated forwards and carried to a station further down the line where the centering pins are inserted in the moulds (the only special feature of these moulds). The moulds are then pressed together to better seal the two halves of the product.
The speed of this operation is so quick that the object placed inside one of the two halves of the product does not move during bonding.
Solid products are usually bonded after dosing but before the final cooling stage when the product is still semi-fluid.
Hollow products, on the other hand, are usually heated before being bonded so that the edges slightly melt and the two halves are then sealed together as a result of solidification.
This system has several advantages:

• the surfaces are brought into perfect contact with each other 
• the moulds and plant are kept clean
• the system is easily adapted to produce different items
• any type of filling (except, of course, liquid ones) can be used 
• hollow items containing surprise gifts or other objects can be bonded

This system can handle up to 30 moulds (or 15 pairs of moulds) per minute and guarantees an excellent production rate.
