摘要:
The apparatus allows to automatically change the bobbin cases in quilting machines. The apparatus comprises a pick-up element (37) which is mounted on a carriage which can move between a magazine (38) which contains full cases and the hook assembly (3) of a sewing machine in which the empty case is to be replaced. The pick-up element (37) extracts the empty case and deposits it into a specifically provided container (64). It is further positioned at the magazine (38), from which it removes a full case and transfers the case into the hook assembly (3).
摘要:

摘要:
A device for positioning and joining at an angle, by means of a sewing machine (1), the borders (B P , B F ) of two flaps of fabric, particularly of a horizontal cloth (P) and of a vertical band (F) for forming the case of a mattress, having an angular element (5) which comprises a first laminar channel (31), forming a guide for the border (B P ) of the cloth (P), and a second laminar channel (30), which forms a guide (P F ) for the border of the band (F); the channels (30, 31) are arranged at a right angle and each channel is comprised between two walls (25, 26; 27, 28): one wall (25, 26) is external to the channels and the other wall (27, 28) is internal thereto; respective through openings (32, 33) are formed in the outer wall and two feeders are also provided which comprise rotating heads (42, 43) which are arranged so as to tangentially engage the cloth (P) and the band (F) through the through openings (32, 33) in order to place the borders of the cloth and of the band, guided in the channels, adjacent to each other.
摘要:
The apparatus has a structure with two frames (8,9) which can move towards each other and between which the mattress (M) is locked. The frames (8,9) support a plurality of devices (13) for applying the quilting braces (P). Each device comprises a needle (32), to which a quilting brace (P) is coupled; the needle (32) is driven through the mattress (M). On the other side of the mattress (M) there is provided a unit (15) which applies a tuft (Z) to the quilting brace (P) guided by the needle (32). During this operation, the mattress (M) is compressed so that once it is released it expands and tensions the applied quilting braces (P).

The apparatus has a pair of chains (19,20) on which a bar (26) is transversely fixed. The bar (26) is provided with clamps for gripping the front edge of a cloth to be quilted. The chains (19,20) move the cloth from a position for gripping its front edge to a quilting position, where it is transferred onto the clamps of a carriage (49) which transfers the cloth onto a removal device.
摘要:
A station (1) for closing a covering for blocks (A) made of deformable material, which comprises a resting surface (2) for at least one block (A); the station (1) comprises at least one clamping pusher (3a, 3b), which is aligned with at least one head (B) of the block (A) and can translate toward the surface of the block (A) until it is pressed for the compression of a covering sheet (4) on the block (A), and comprises grip means (5) for retaining juxtaposed end flaps (4a, 4b), (4c, 4d) of the sheet (4) that protrude from the block (A), the grip means (5) being able to translate according to a stroke for approach/spacing apart with respect to the block (A) in order to pull the sheet (4).
摘要:
A frame (1) for sewing upper pillows (A) on covering shells (B) for mattresses (C), which comprises four perimetric walls (3); each wall (3) is perpendicular to the two contiguous walls (3) and comprises at least one laminar portion (4) that constitutes a resting surface, the laminar portion (4) being co-planar with a lower edge of the respective wall (3), at least one of such walls (3) comprising at least one locking element (5) for at least one component, selected from between an upper pillow (A) and a covering shell (B), arranged on a respective laminar portion (4).
摘要:
A device (1) for feeding an apparatus for applying tufting straps (P) to a mattress (M) with disks (D1, D2) for backing the tufting straps, the device comprising a support (2), a channel (3) which is formed in the support for guiding at least one tape (N) unwound from a reel in order to form the backing elements of the tufting straps of the mattress, the channel (3) having an outlet connected to the apparatus, an advancement element (3a) for the advancement of the tape along the channel (3) by a preset step, and a cropping element (37) for cropping the tape at each step and forming disks (D1, D2) whose length (L) substantially matches the step.
