摘要:
An apparatus for bordering mattresses, comprising two mattress bordering assemblies, arranged at upper and at lower levels and provided with superimposed worktables being provided with mattress overturning devices, a mattress distribution assembly arranged upstream of the bordering assemblies to send the mattresses individually to the upper worktable or lower worktable, a chute arranged at the output of the worktable of the upper assembly and inclined to convey the mattresses bordered by the upper assembly toward a receiving table, the chute comprising actuatable movable elements, in order to allow the advancement of the mattresses from the upper worktable toward the receiving table.

A tucking attachment for a sewing machine having a tucking blade with one end positioned adjacent material and a tucking blade drive with an output shaft mechanically coupled to the tucking blade. A control, connected to the tucking blade drive, is operable to command the tucking blade drive to move the tucking blade through a programmable displacement to form a tuck in the material adjacent a presser foot of the sewing machine. Thereafter, the sewing machine is operated to sew a number of stitches in the tuck, and the tucking blade is then retracted. Repeating the above cycle of operation permits successive tucks of different lengths to be formed in the material.

A machine for automatically producing a mattress border with handles sewn to the border material. Border material is pre-fed from a selected spool, screened for splice avoidance and measured. Handle material is fed from a selected spool mounted in a multiple handle material spool magazine mounted on rails, fed into a handle folding assembly, and cut to length. Ends of the handle material are folded under by the handle folding assembly and the handle then transferred in a folded condition from the handle folding assembly to a correct position on the border material. A double frame handle press holds each folded end of the handle material in place as each end is maneuvered under a sewing head needle to apply a stitch pattern to secure the folded ends to the border material. The double frame handle press is translated separately from the carriage assembly which travels in the sew pattern, to position the other end of the handle under the sewing needle.

A compressed air operated ergonomic system used with a tape edge machine carriage employed in mattress manufacturing. The operator's arm, leg, knee, or foot can be used to stop the sewing operation and stop the carriage from moving around the table. The compressed air system can also provide an operator air source, engage the gear mechanisms which permit the carriage to move around the table, provide needle cooling, and permit the sewing machine presser foot to be raised.

A device for sewing the edges of a mattress contains a movable supporting face, a sewing mchine, and a swingable arm cooperating with holding means for swinging the mattress around one of its corners. Furthermore, sensors for sensing the position of the mattress are provided, as well as a control device for activating the swingable arm, dependent on the signals issued by the sensors. The control device also contains counting devices and memory elements for automatically stitching one complete edge of a mattress.

The tape-like facing band is fitted annularly around the carcass (M) and the front surface of the casing is supported on said carcass, which is received in a containing structure (3) with a boundary edge (3B) from which the carcass and the facing band partially project; a guide rail (7,9) extends around said edge for a supporting carriage (20) which has orientable rollers (24) for passing over the curves at the corners and is motorized; a further trolley (42) is movable on said rails and connected to said supporting carriage by an articulation (40); a cutter (18) is capable of acting in a position in front of that of the stitcher.
摘要:
A method for sewing together fabric pieces which comprises the steps of sewing elastic cord-like core material such as polyethylene cord along the edge portions of two or more fabric pieces, automatically engaging the edge portions of the fabric pieces with each other by guiding the sewn core material, and sewing together the engaged edge portions to render an assembly of fabric pieces adapted for use as a cover; and a machine for sewing together fabric pieces which is provided with a core material-guiding mechanism for clamping core materials previously sewn to the edge portions of two or more fabric pieces being sewn together, thereby engaging the edge portions with each other.
