Advantages Of Needle Feed

Needle Feed “Needle Feed as shown in Figure 7.7 utilizes a feed dog below the throat plate that rises up through the plate, presses the fabric against the presser foot, in combination with the sewing needle which drops through the fabric, and then both the feed dog and needle move one stitch to move the fabric”. Then they separate and return to their respective original position for the next stitch formation. FIGURE 7.7 Needle feed mechanism (Source: http://textileapex.blogspot.in) Needle enters the fabric and stay in the fabric when moving the fabric in perpendicular to the needle’s normal direction, thus feeding the fabric along with the feed dog. It prevents the upper, middle, and lower layers of fabric panels from slipping with respect to each other. It does not need pressure against the surface of the fabric during feeding which could be useful for delicate fabrics where the impression of feed dog will be marked on the fabrics. It is commonly used in combination with drop feed and/or with upper feed. It is predominantly utilized in bulky sewing circumstances like while quilting the fabric and for sewing heavy materials like leather, carpet etc. The three main kinds of needle feed mechanisms are Upper pivot needle feed, Central pivot needle feed and Parallel drive needle feed. The pivoting needle feed devices move the needle at definite angle to assist the feeding of fabric, however parallel drives simply move the needle back and forth (Clayton 2008).…show more content…
Hence, the sewing needle enters the fabric at a leading angle with respect to centerline of needle and will exit the fabric at a trailing angle. This would appear to disturb the fabric and the sewing process, but practically it does not (Clayton

    When given intramuscularly the autoinjector can deliver the drugs faster with rapid absorption compared to manual injection due to the spray effect of drug delivery in autoinjector. In the autoinjectors the needle is not visible outside and hence do not cause any fear. The injection will be painless, easy to administer and well suited for mass casualty management. When healthy volunteers were administered atropine and pralidoxime chloride through autoinjectors
