摘要:
A method and apparatus for sewing a cloth handle to the side panel of a mattress or box spring. The apparatus includes a modified X-Y programmable sewing machine which can sew both ends of a handle to the side panel in sequence without the necessity of removing the handle and side panel from the clamp and manually adjusting the position of the side panel. The apparatus also includes a folding jig, and a clamp with an upper lip to retain the handle in a desired position. The method includes the steps of folding the handle and placing it within the clamp on the sewing machine, and thereafter sequentially stitching each end of the handle to the side panel automatically without removing the handle from the clamp or without manual movement of the side panel.

A method and apparatus for sewing flange material to a fabric panel, preferably the top or bottom panel of a mattress sack. The apparatus includes a sled which pulls the fabric panel to and through the sewing machine. The apparatus also includes an edge guide that guides one edge of the panel to the sewing machine as well as provides a thickness measurement of the panel and smooths the fabric panel prior to sewing. The apparatus also includes a moveable dolly which carries the sewing machine find the flange material, and a wheel which engages the fabric panel during movement of the sewing machine away from the fabric panel to prevent movement of the fabric panel. The apparatus also includes apparatus for automatically removing the fabric panel from the table after completion of the sewing operation, as well as a cutter for cutting the trailing flange material and the sewing threads. The method of this invention includes the steps of sewing each edge sequentially, rotating the parcel around the corners while cutting and sewing the corners, and measuring the thickness of the panel to space the rotating arm from the table a specified distance less than the thickness of the panel. The method also includes the steps of adjusting the speed of rotation of the edge flattened to produce a flattened corner without wrinkles or ridges.
摘要:
Sewing apparatus for joining a first panel and a second panel and having an arm that is rotated about an axis normal to the surface of the first panel to rotate the first panel, a shoe biased to follow an edge of the first panel as the first panel is fed to the sewing machine, a detector to monitor the shoe and provide a signal indicative of a longitudinal orientation of the edge of the first panel, and means for adjusting the longitudinal orientation of the first panel with respect to a true feed direction in response to the longitudinal orientation signal. An edge flattener including a generally cylindrical component is provided.

A sewing machine apparatus and method for sewing a label to a thick, puffy, or quilted mattress is disclosed. The apparatus includes a pair of clamps attached to a carriage, a cutter and nipper disposed above the carriage, and a controller for controlling the sewing machine and carriage.
摘要:
A method and apparatus for stitching a label to material in which the material and label are joined face side down rather than face side up. The label is held face side down with a clamp and a panel is held over the label by a clamp. The label and panel are joined by a sewing machine. Further, a mechanism is provided for activating a thread knife of the sewing machine at such a time that the bobbin thread only is cut. A masking mechanism is provided for masking electronic signals of the sewing machine that would otherwise cause the machine to reset at a normal needle height, so that a sewing operation can be stopped with a needle at a maximum clearance position. Pneumatic cylinders and linkage are provided for raising the needle and presser foot at the end of a stitching operation.

A method and apparatus for maniuplating and sewing first and second panels together is disclosed including a rotatable arm for rotating a first panel and control means for reducing the stitching speed in response to detection of a comer of the first panel.
摘要:
A system for manufacturing a mattress comprises multiple modules or stations used to sew together multiple components into a casing. A spring or other core is inserted into the casing before a top is secured to the casing to complete the mattress. More or more flanges may be incorporated into the casing for securing the core inside the casing. The system provides an operator flexibility to manufacture different types of mattress with minimal changes.

A bedding foundation is manufactured with a cover having a welt cord extending upwardly to create a seal when a mattress is placed on the foundation. The cover is made using a two stage process. During the first stage a sewing machine is used to join a welt cord to a web of border material. In the second stage a second sewing machine sews a piece of non-skid decking to the border assembly. Fullness may be incorporated into the border material to enable the cover to fit around the corners of the bedding foundation with the welt cord being spaced inwardly from the perimeter of the foundation.
摘要:
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.
