Automatic machine for the application of self-adhesive handles on a variety of clustered products.
On each track the packs arrive on the machine infeed conveyor, and are then automatically slowed down and spaced via a series of Intralox conveyors. The adhesive tape is unwound by an electronically controlled motor-driven roller as a function of pack flow. Application of the cardboard (or other materials) on the adhesive is carried out continuously by a mechanical double cam system. The thus-obtained handle is applied to the transiting cluster by a continuously moving set of pneumatically operated arms.
Cutting of the adhesive tape is performed by a unit with a cam-guided blade. The machine PLC oversees and controls the whole cycle and ensures proper repetition of movement.
The machine can also be equipped with a mechanical device (optional) that gives the handle an arched shape, a must on certain products. Handle and cardboard alignment is electronic, allowing the machine to correct any errors autonomously via automatic repositioning.
The handle tape is made of transparent mono-oriented polypropylene coupled to the cardboard (or other materials), which may be plain, coloured or printed with promotional text and/or images. Each head can be provided with a second reel holder for 5000-metre adhesive tape reels. All machines can work with pre-laminated adhesive tape reels.
Our machines can manage different types of handles:
- cardboard handle and adhesive tape and the two materials are joined by machine
- handle with pre-labeled adhesive tape, the already unwound handle complete with the two materials
- soft touch handle, with adhesive tape and handle called “mousse”, the two materials are joined by machine
