Definitions
- the invention relates to a pocket sewing template for an automatic sewing machine for sewing a blank onto a garment pad or other mat for use in creating an attached garment cargo pocket by sewing the blank to the garment pad comprising a panel which abuts against the blank and for holding down the blank during sewing, provided with a peripheral edge region and with a groove in the plate as a predetermined needle path on the blank, the plate having at least one recess provided therefor and disposed at a location of the plate is to exclude a section of the blank while holding down the latter
- Cargosets are particularly problematic in their automated manufacture of garments.
- Cargos are usually rectangular in shape or square in shape and are provided with a bellows-fold at each of their side edges which allows the bag to be set up. Due to the adjustability, the receiving volume of such bags can be increased.
- the blanking of the bag, including the cargo fold is prefabricated, which is sewn onto the garment to create the bag.
- the automated sewing such on two side edges with a bubble bellows provided Cargofaltung therefore turns out to be particularly difficult and time-consuming, because the blank in the folded (folded) state of the edge area must be sewn onto the garment pad, but this by the top layer of the fabric section of Cargofaltung is covered.
- CONFIRMATION COPY bent over, that is, this edge region turned inwards, so that the cut edge of the blank is covered.
- the blank is placed in the clamped state on the garment pad and fed to a sewing machine of the sewing unit.
- the upper layers of the cargo fold area of the cloth section are then pushed to the side by means of a material slider, which are in the way of a sewing process.
- rectangular recesses are present in the sewing template, which extend over almost the entire length of the two side edges and parallel to them.
- the boundary walls of the recesses In the direction of the perpendicular to the two side edges of the base edge of the bag and thus also perpendicular to the base edge of the sewing template, the boundary walls of the recesses also extend parallel.
- the recesses must be relatively large, since the upper layers of the Cargofalten Anlagens the fabric section must be pushed over their entire length to the side.
- the two upper layers of the cargo folding area are hereby moved one after the other and the sewing machine has to start sewing the entire U-shaped seam at two points of the sewing template. This solution is relatively complicated by the required feed valves.
- the invention is therefore an object of the invention to provide a device and a method for the production cargo pockets with the highest possible degree of automation of manufacturing, which also has the highest possible manufacturing accuracy.
- the plate with at least one receptacle for receiving a raised corner portion of the blank, as well as with both sides of the recording adjacent flat portions of the plate (sewing template) for holding down at least one folded part of a Cargofaltungs Scotlands is provided.
- the at least one receptacle should preferably be open over its entire area.
- a pocket sewing template for use in a sewing machine system in such a way that it has means with which during the sewing process the areas of the cargo folds be held down on two adjoining upper side edges of the Cargofaltungen in the folded or unfolded state at which the seam is to take place for attachment of the blank to the base.
- a corner region of these two edge regions of the blank with cargo folds is not held down according to the invention.
- this should be at least one corner as possible unloaded by the sewing template and free from other forces acting on it from outside forces, in particular and advantageously free of compressed air.
- the respective corner area should therefore by a corresponding structural design of the plate of Taschenaufnähschablone, have the opportunity to be aligned by the holding down of the adjacent folded upper sections of Cargofaltungen resulting establishment of the respective corner area as possible unloaded by the plate and set up.
- at least one receptacle which can also be referred to as a receiving element, is provided for this purpose, in which the respective corner region of the upper part of the cargo fold of two adjacent side edges of the pocket to be sewn is located during the sewing process.
