Abstract:
A machine for fastening a load having a given size, comprising:a machine frame positioned around a central axis intersecting a point where, in operation, the load is brought; a delivering carriage onto which a roll of flexible material is rotatively mountable, including an output delivering means for delivering the flexible material as a rope, the delivery carriage comprising first and second parts connected by means of a pivot axis, the first part being connected to a movable support, the output delivering means being mounted on the second part; first controllable moving means for producing a relative radial movement of the output delivering means with respect to the central axis, the first controllable moving means comprising a controllable cylinder having two extremities connected respectively to the first and second parts of the delivering carriage for pivoting the second part with respect to the first part by means of the pivot axis to produce the relative radial movement of the output delivering means with respect to the central axis relative rotating movement of the rope with respect to the central axis; a second controllable moving means for producing a relative rotating movement of the rope with respect to the central axis, the second controllable moving means comprising a motor, a ring gear connected to the motor and mounted within a gearbox, a rotary arm connected to the ring gear, and a boom onto which the delivering carriage is mounted so that the relative rotating movement of the rope with respect to the central axis is produced by rotating the delivering carriage by means of the motor; a third controllable moving means for producing a relative axial movement of rope in a direction parallel to the central axis; and controlling means for controlling: the relative radial movement by means of the first controllable moving means in view of the size of the load; and the relative rotating and axial movements by means of the second and third controllable moving means to fasten the load with the rope once the radial movement has been produced.
