An automatically fabricated composite material pattern piece is formed with an outer and inner fabric sheet secured together along a pattern seam line by stitching or heat glue fusing. Seam allowance flaps are formed adjacent pattern seam lines and project outwardly from under outer edge portions of the outer fabric sheet to provide for attachment of the composite material pattern pieces together in a specific order to form a finished fabric article.

A foot-operated controller of a sewing machine including a first pedal that input a number of revolution of a sewing machine motor by stepping of a user, a second pedal pressed by the user, a main body that supports the first pedal, and a support unit that supports the second pedal, in which the support unit is selectively attachable in disposition where the second pedal is on the left side of the first pedal and disposition where the second pedal is on the right side of the first pedal. In both cases where the second pedal is on the left side of the first pedal and the right side of the first pedal, across an interval between the main body and the support unit, it is possible to detect the pressing to the second pedal with respect to the second element.

A method of fabricating pattern composite fabric pieces by an automatic pattern fabric article piece processing machine is described. A composite fabric sheet is fed in the processing machine onto a conveyor having a permeable belt under which is provided a vacuum chamber to retain the fabric sheet stationary while a laser cutter effects a programmed job function. The machine forms seam allowance flaps for the composite fabric pattern piece. A stitching or ultrasonic bonding machine also forms seams. In a further stage, printed matter may be applied to the allowance flaps. Glue may also be applied to the flaps and labels to some of the pattern fabric pieces. By interconnecting the seam allowance flaps of different fabric pieces, in a specific order, a fabric material article is produced.

A waste catch plate for sewing machine held between a sewing machine and a table, and catching wastes produced by a sewing work by the sewing machine, and the waste catch plate includes a plate main body in a tabular shape. The plate main body includes a placement plane provided in a partial region of the plate main body, and on which the sewing machine is to be placed, and an opening provided in a remaining region of the plate main body continuous and adjacent to the partial region, and to which a bag for collecting the wastes is attached. Provided on a back surface of the region of the plate main body where the placement plane is provided is a thin leg spreading on the back surface so as to cover a region surrounded by multiple legs of the sewing machine being placed on the placement plane.

This application presents a solution for measuring different physical parameters from the felt and its surrounding environment, such as: pressure, temperature, humidity, pH, airflow and the degradation of the felt. It is disclosed a monitoring system, comprising: an independent measuring unit fixed in a felt, comprising at least one of the following sensors: temperature, humidity, pH, pressure or air flow; a central acquisition unit comprising a microcontroller, a real-time clock, a communication transceiver connected to at least one independent measuring unit and a communication transceiver connected to a computing device; and a polymeric encapsulation material layer. Applications for this technology are the monitoring of the felt and its surrounding environment in, for example, dry filtration, laundries, wet filtration and other suitable applications. Although the system is focused specifically on felt, the same principles could be applied to other types of fabrics with no further modifications to the system.
