Definitions

  • the invention relates to a method for producing fitted sheets or similar protective covers, in which rectangular pieces of cloth are cut from a web product, each corner of the pieces of cloth is placed on top of one another, the areas lying on top of one another are connected by a seam at a distance from the tip of the corner of the piece of cloth and are connected via The point protruding from the seam is cut off, so that a block-like cover or piece of cloth is formed.
  • this process can only be carried out manually, so that the time for completing the fitted sheet or the like depends on the work performance of the manually operating person.
  • the accuracy of the production of the corner areas, which should preferably form an exactly vertically directed edge, is also dependent on the skill of the manually operating person.
  • the fact that this procedure can only be carried out manually is essentially due to the fact that each piece of cloth has to be folded diagonally at the corner, which means that part of the piece of cloth in the corner area has to be turned up from a horizontal plane in order to get the corresponding one To form a cloth envelope in the corner. Such a procedure is practically impossible to implement mechanically or automatically.
  • the invention is based on the object of creating a method of the generic type in which an exact, precise and machine-executable design of the corner areas is made possible.
  • the piece of cloth is held at two holding points in the region of a corner near the two edge edges forming the corner at a distance from the tip of the corner, which corresponds to the web height of the block-like cover or the like to be formed.
  • the bar height later determines the height of the vertical edge of the cuboid cover. The holding points fix the piece of cloth in reached the corresponding area.
  • the first stop which is located on the first edge, is shifted parallel to the plane spanned by the piece of cloth to the second stop, which is located on the second edge of the piece of cloth.
  • the corresponding area of the piece of cloth is taken along so that the two holding points are then held one above the other and a cloth tip is formed in the form of a right triangle.
  • the hypotenuse of this triangle is opposite the apex formed by the breakpoints.
  • the first leg of the triangle forms an extension of the second marginal edge of the piece of cloth, while the second leg, which is directed at right angles to the first leg, forms the area of the seam and separation point to be attached.
  • the tip of the cloth is then provided with the seam along the second cathetus and cut off next to the seam so that the seam is retained, but the tip of the cloth is separated. Then the finished piece of cloth can be released at the breakpoints.
  • the corresponding corner area is then formed in terms of shape in such a way that when all four corner areas are finished, a cuboidal reference is created.
  • the particular advantage of this procedure is that no turning of the piece of cloth is required to form the corner area or the cloth tip, which is automatically not practicable or difficult to control, but the areas of the cloth piece located in the area of the cloth tip are superimposed by shifting the holding points placed so an exact and also machine-executable manufacturing method is enabled.
  • the corresponding procedures on both elements are required in both corner areas (front corner areas or rear corner areas) when forming the corresponding cloth tips, which can optionally be done simultaneously.
  • the procedure can also be carried out in such a way that a corresponding tip of the cloth is first formed, sewn and cut off in a corner area and the formation of the tip of the cloth is already started in another corner area during the sewing and cutting off. An overlapping processing of the piece of cloth is thus realized, which reduces the time required for the overall production.
  • front and rear corner areas are processed simultaneously.
  • the method and the individual method steps are operated by means of machine, automatic, electrical, pneumatic and / or electronically controlled devices.
  • This procedure makes it possible to use relatively simple devices that are easy to control, because only vertical and horizontal movements are required to form the corresponding cover. Contrary to the state of the art, it is not necessary to turn over areas of the cloth and thus do not require any effort. This simplifies the overall procedure and enables the procedure to be carried out by machine.
  • a device for the production of fitted sheets or similar protective covers is also known, which are formed from a cut web product to a cuboid-like cover, with a transport device for transporting separated pieces of cloth in a flat orientation.
  • Such a device is for example from the DE 35 42 445 C1 known.
  • the invention provides that in each case in the area of a corner of the piece of cloth near the two edge edges forming the corner at a distance from the corner that corresponds to the web height of the block-like cover or cloth to be formed, mechanical gripping means are arranged, which fix holding points of the piece of cloth in a closed position and release in an open position that a first of these gripping means can only be adjusted in a direction directed vertically to the plane of the piece of cloth, in particular for opening and closing or also in the closed state, that a second of these gripping means for opening and closing is also adjustable and is preferably also vertically adjustable in the closed state in a position in which the gripping means are shifted above or below the plane of the piece of cloth, this gripping means in particular in a vertically adjusted position or without vertical adjustment is horizontally adjustable or is pivotable about a vertical axis from the basic position or the vertically adjusted position into a working position in which the second gripping means is positioned above or below the first
  • corresponding gripping means are arranged which can be positioned in an open position and fix the corresponding holding points of the piece of cloth in a closed position.
  • a first of these gripping means is only adjustable in a direction directed vertically to the plane of the piece of cloth for opening and closing, so that this only serves to fix the piece of cloth in a defined holding point, which can be marked, for example.
  • the second of these gripping means is also intended to be positioned in an open position over the preferably marked holding point of the piece of cloth and then to be transferred into the closed position.
  • the second gripping means can be adjusted vertically into an intermediate position in which the gripping means are displaced above or below the plane of the piece of cloth.
  • this gripping means can be adjusted horizontally or, for example, pivoted about a vertical axis so that the gripping means executes a movement parallel to the plane of the cloth.
  • the second gripping means is thus transferred into a working position in which it is positioned above or below the first gripping means.
  • the two holding points defined by the gripping means are positioned one above the other.
  • the protruding area is fixed with the sewing device by attaching a corresponding seam and the cutting device cuts off the tip next to the seam so that the corner area is completed.
  • the gripping means can then be opened and returned to the starting position be put on hold so that they are ready for the processing of the next process.
  • the corresponding device components can be arranged, for example, in a direction of transport of the piece of cloth which is parallel to the longer edge of the piece of cloth, at both front ends of the piece of cloth in a mirror-symmetrical arrangement. They can also be arranged at the rear end of the piece of cloth in a mirror-image arrangement to the arrangement at the front end of the piece of cloth.
  • the workflow can be accelerated by a corresponding plurality of device components in that not every corner area is completed one after the other, but rather two or even all corner areas are processed and completed at the same time.
  • the cutting device can be moved along a side edge of the piece of cloth or parallel thereto when the first and second gripping means are in the working position.
  • the sewing device can be moved along a side edge of the piece of cloth or parallel to it when the first and second gripping means are in the working position.
  • the drawing figures serve to illustrate a method according to the invention for the production of fitted sheets or similar protective covers clarify.
  • rectangular pieces of cloth 9 are cut off from a web product. Such pieces of cloth can be omitted all around, for example. It can also, as in Figure 1 It is made clear that elastic bands 10 can be sewn or sewn on the edge or sewn into the hem.
  • the inventive method is determined and suitable. Particular importance is attached to the fact that the web height, that is to say the height of the part 11, can be determined in a simple manner and that the corner areas run exactly vertically, that is to say the lines beginning with 12 in Figure 2 are directed as exactly as possible vertically.
  • the piece of cloth 9 is in the area of each corner 1.5 near both edge edges forming the corner 1.5 at a distance from corner 1.5, which corresponds to the web height 12 of the block-like cover 11 to be formed, at two holding points 2.3; 6.7 held.
  • the first stop point 2; 6, which is located on the first edge 13, 13 ' is shifted parallel to the plane spanned by the piece of cloth 9 to the second stop point 3; 7 while taking along the corresponding area of the piece of cloth 9.
  • the first stop position is shown with the corresponding stop points in the basic position.
  • Figure 8 the positioning of the breakpoints is shown one above the other.
  • the tip of the cloth is provided with the corresponding seam 18 along the second cathetus 17, with the tip of the cloth next to the seam 18 finally being severed and removed.
  • the piece of cloth can be released at the holding points 2, 3, 6, 7 and, for example, placed on a pile of cloths.
  • all four corners of the piece of cloth 9 are processed and finished in a corresponding procedure.
  • an arrow indicates a possible transport direction of the piece of cloth 9 through a corresponding device.
  • two front end regions of the piece of cloth in the transport direction 19 can be processed at the same time and correspondingly two rear corner regions of the piece of cloth can also be processed simultaneously, for which a corresponding arrangement and configuration of device components is required. It is it is also possible that all four corner areas are processed at the same time.
  • the method and the individual method steps are operated by means of machine, automatic, electrical, pneumatic and / or electronically controlled devices.
  • the formation of the ear is particularly clear from the sequence of Figures 3, 4 and 5.
  • the reference point 4 or 8 is a reference for the required sewing device 20 or the separating device 21.
  • the piece of cloth 9 is preferably moved in the direction of the arrow by means of a transport device 19 transported.
  • the transport device can for example be a belt drive or another suitable element.
  • These gripping means 22, 23 correspond to the holding points 3.2 and 6.7, respectively.
  • a first of these gripping means can only be adjusted in a direction 24 directed vertically to the plane of the piece of cloth 9 and opposite to this direction for opening and closing.
  • the second gripping means 23, 23 ' is also vertically adjustable for opening and closing and can also be produced in the closed state in a position along the arrow 25 in which the corresponding gripping means 23 are shifted to a position below the holding point of the gripping means 22, this gripping means from the vertically adjusted position can also be horizontally adjusted in the direction of the movement arrow 26, namely into a working position shown in FIG Figure 9 is shown, in which the second gripping means 23 'is positioned below the first gripping means 22 so that a tip of the piece of cloth is formed, which protrudes over a longitudinal edge 13 of the piece of cloth 9.
  • the movement of the second gripping means 23 can also take place in such a way that it moves out of the position according to FIG Figure 6 in the position according to Figure 8 is transferred by a circular movement, as is indicated by the movement line 27. Then can then by means of a sewing device 20, a seam 18 along the longitudinal edge 17 over which the tip protrudes can be produced and the tip cut off by a cutting device 21.
  • the sewing device 20 and the cutting device 21 can be stationary, namely when the piece of cloth 9 is moved according to the movement arrow 19 or the sewing device 20 and the separating device 21 can be moved against the movement arrow 19 or in the direction of the movement arrow 19 be mounted on device components.
  • the invention is not restricted to the exemplary embodiment.
  • the second gripping means 23 is not moved below the plane spanned by the piece of cloth 9, but above the plane, so that the gripping means 23 ′ lies above the gripping means 22 in the end position. This would correspond to a convolution as shown in Figure 5 shown on the left.
