ABSTRACT:
An article such as a broom back coated with a covering comprising a layer (9) of thermoformable plastic material. The broom backs (1) are introduced in a chamber (6) of a thermoforming machine (5) radiating panel (8). A plate of thermoformable material is put on the broom backs (1) and by the action of the heat radiated by the panel (8) and under vacuum condition the plate melts forming a layer (9) which wraps the broom backs (1) almost completely. The coating layer (9) thus formed after deformation maintains its colour and brightness and inscriptions and fancy drawings can also be preprinted on it. The covering formed by said layer (9) comprises an upper and a side surface completely wrapping the upper and the side faces of broom backs (1) and a lower bent edge partially coating the lower face (2a) thereof. The layer (9), which preferably is of PVC or polystyrene, advantageously preprinted, is firmly secured to the broom backs (1) after cooling.
