A frame for sewing upper pillows on covering shells for mattresses, which comprises four perimetric walls. Each wall is perpendicular to the two contiguous walls and comprises at least one laminar portion that constitutes a resting surface: at least one of the walls comprises at least one locking element for at least one component, selected from between an upper pillow and a covering shell, arranged on a respective laminar portion; at least one of the walls comprises at least two bands that are mutually aligned and can slide with respect to each other in order to vary the overall length of the wall; a linear actuator is interposed between the at least two bands of the wall, for the controlled mutual sliding of the bands; the actuator being adapted to be controlled by a respective control and management unit of a sewing machine that is functionally associatable with the frame.
A frame for sewing upper pillows on covering shells for mattresses, which comprises four perimetric walls, each wall being perpendicular to the two contiguous walls and comprising at least one laminar portion that constitutes a resting surface, said laminar portion being co-planar with a lower edge of said wall, at least one of said walls comprising at least one locking element for at least one component, selected from between an upper pillow and a covering shell, arranged on a respective laminar portion, wherein at least one of said walls comprises at least two bands that are mutually aligned and can slide with respect to each other in order to vary the overall length of the wall, between said at least two bands of said wall there being interposed a linear actuator for the controlled mutual sliding thereof, said actuator being adapted to be controlled by a respective control and management unit of a sewing machine that is functionally associatable with said frame.
A machine for sewing upper pillows on covering shells for mattresses of the type comprising a supporting structure for at least one retention frame for upper pillows and covering shells for mattresses, which is associated with respective movement elements that are arranged on said structure, and a guiding track for at least one sewing head, said sewing head being able to perform a translational movement along said track in a direction that is perpendicular to the movement direction of said frame on said structure, further comprising a control and management unit provided with at least one memory stage for storing data strings relating to a plurality of predefined measurements of upper pillows and covering shells for mattresses and to parameters for sewing the pillow on the shell, which is associated with a user interface for entering and selecting said data strings, at least one wall of said frame comprising at least two bands that are mutually aligned and can slide with respect to each other in order to vary the overall length of the wall, between said at least two bands of said wall there being interposed a linear actuator for mutual sliding, which is actuated by them and is controlled by said control and management unit.
