Abstract
A method and apparatus are disclosed for wrapping an object in a sheet. A retainer formed with a slot is moved along a work path. A piece of sheet is supplied across the opening of the slot; then the object is inserted into the slot and pushes the sheet to the back of the slot against the retainer, with the edges of the sheet sticking out between the object and the edges of the slot, with part of the surface of the object being free; then a pressure plate is placed adjacent to the free surface, the outward facing surface of this plate being smooth; then first one, and then the other, protruding edge of the sheet is wrapped round the object and over the pressure plate by an embracing arm, so that the edges of the sheet overlap; then these edges are joined by a joiner bearing against the smooth part of the pressure plate; and then the wrapped object is discharged from the retainer.
