An apparatus for feeding a quilting machine with a cloth (P) to be quilted, composed of superimposed sheets (T1, T2, T3) which are unwound from respective rolls (C1, C2, C3) in an advancement direction (B), and comprising longitudinal gripper elements (19, 20, 21, 22) which can move between a closer position for gripping the lateral edges of said cloth (P) which are parallel to said advancement direction (B) and a spaced position for widening the cloth (P), transverse grip means which are arranged downstream of said longitudinal gripper elements (19, 20, 21, 22) and are associated with elements (11, 12) for conveying the cloth (P) and means (10) for the transverse locking of the cloth (P) which are arranged upstream of the longitudinal gripper means (19, 20, 21, 22), auxiliary means (29) being arranged upstream of the transverse locking means (10) and being suitable to act on the upper sheet (T2) and produce an elongation thereof with respect to the underlying sheets (T1, T3).
摘要:
A bath dresser (1) with simplified structure, comprising a supporting framework (2) that supports, in an upward region, a tub (20) that can be closed in an upward region by a changing surface (30), and further comprising pivoting means provided with a bracket (31) that is associated with the edge of the changing surface (30) and rotatably engages an upper frame of the framework, disengageable locking means (36) being further provided in order to retain the changing surface (30) in a raised position so as to allow disengagement.
摘要:
An apparatus for inserting tuft assemblies (P) through a mattress (M), with retention disks (D1, D2), comprising a mattress locking structure composed of: two walls (2, 3), flat and parallel with a space for accommodating the mattress for compression; a first carriage (11), supported by one (2) of the walls with a first disk feeder (87a) and a tuft insertion device (10); a second carriage (23), supported by the second wall (3) supporting a second disk feeder (87); an actuator (13-20; 24-31) for the carriages (11, 23); each one of the feeders (87, 87a) for disks (D1, D2) comprises a disk magazine (91) that is supported on a respective carriage (11, 23) and contains disks arranged in stack acted upon by a pusher (93) in order to keep a front disk (D1a, D2a) of the stack in a pick-up position; and pick-up elements each with a transfer element (36, 51, 59, 64), supported by a carriage.
摘要:
A magazine for a plurality of reels (3) of tape (2) provided with a device for selecting a reel of tape to be used, comprising a plurality of supports for the reels, which can slide on a guide (8) so that the reels form a stack whose axis is parallel to the guide, elements (9,13) for actuating simultaneously the plurality of supports along the guide (8) in order to position the reel (3) of tape (2) to be used in a preset point of the guide (8).
摘要:
A machine for packaging a mattress in a sheet, comprising horizontal supporting and receiving mattress surfaces, guides (3,18,19) for guiding the sheet (4) on a vertical plane, so that by moving the mattress in the advancement direction (7) from the supporting surface (1) toward the receiving surface (5) the sheet is arranged over and under the mattress, a device for joining and cutting the sheet upstream of the mattress and for forming a bag which wraps around the mattress, sheet unwinding assemblies (27,28) comprising two rollers (42,42a) movable along the receiving surface with a return stroke, the rollers (42,42a) being articulated to rotate between alignment and parallel positions in which they are perpendicular or parallel to the advancement direction (F) and to the sides of the mattress, and actuators (45,45a) for actuating the rollers (42,42a).
摘要:
A device for positioning and joining at an angle, by means of a sewing machine, the edges of two flaps of fabric (P, F), particularly of a horizontal sheet and of a vertical band for forming a mattress case, said device comprising a first guiding wall (17a) for the edge of the sheet (P) and a second guiding wall (17b) for the edge of the band (F), said walls forming mutually adjacent cylindrical sectors (17, 18), two advancement elements being further provided which comprise rotating heads (6, 7) accommodated within cavities formed by said walls, said walls being movable between a position in which said rotating heads tangentially engage the edges of said sheet and said band on said walls in order to advance said edges toward a sewing region and a position in which said walls allow said heads to disengage from said walls.
