A sewing error management device includes a display portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to acquire an error image obtained by drawing an occurrence position of an error on a sewing pattern. The acquiring the error image is based on coordinates representing a formation position of a sewing stitch being sewn at a time point when the error occurs in sewing of the sewing pattern formed by a plurality of sewing stitches. The acquiring the error image is also based on an image showing a shape of the sewing pattern. And the computer-readable instructions further instruct the processor to display the acquired error image on the display portion.

The sewing machine includes a projector, a processor, and a memory storing computer-readable instructions that cause the processor to perform processes. The processes include generating processing of generating a first image including a first object representing a first sewing pattern and generating a second image including a second object representing a second sewing pattern. The first sewing pattern is at least a part of the sewing pattern and is a state in which the sewing is incomplete. The second sewing pattern is a part of the sewing pattern and is a state in which the sewing has progressed further than the first sewing pattern. The processes include projection processing of, after causing the projector to project the first image, switching the projected first image, during the sewing, to the second image, and causing the projector to project the second image.

In one preferred mode, the operator selects by the touch panel 2 a pattern from the displayed patterns on the display 1 and starts the embroidery by operation of the start/stop switch. The CPU 10 is checking the detection signal from the sensor 3 and when the signal is on, the CPU 10 keeps the display 1 in operation. When the operator goes out from the sensor detectable area 60, the signal of the sensor 3 disappears and the CPU 10 generates the LED display 4 indicating the progress of the sewing. Since the operator can see the LED display 4 from the outside of the display visible area 61, the operator recognizes the conditions of the machine A.

A method of forming a patterned carpet in a tufting machine with a sliding needle bar (4) comprising a plurality of needles (5). The method comprising analysing desired pattern data to determine if a problem condition is present for a particular arrangement of tufts in the desired pattern data based on the relative location of at least two stitches in the desired pattern data. Changing the colour of at least one tuft from that required by the desired pattern data to create actual pattern data in which the problem condition is eliminated (or alerting to a user). The problem condition may be the tufts will be spaced by less than a predetermined amount. Alternatively, it may be that a needle (5) forming a tuft in a transitional line is not required to form a tuft for a more than a predetermined number of reciprocations of the needle bar after to the transitional line.
