Description: The present invention relates to an industrial pattern grading template and a method for using such a template for the upgrading or downgrading of all types and parts of a garment, concurrently in all the internationally standardized sizes. Both the template and the method for using it are appropriate for vocational technical training and professional use in the mass production of garments. With the present invention, starting from a single initial size, the concurrent construction of all the required size variations of the different parts of a garment is achieved, with simplicity, certainty and absolute precision, in minimal time without geometry and complex calculations. The template has two sides and a plurality of elongate apertures of variable length and direction. These apertures are adjusted to the basic points of an already constructed garment pattern block, they have appropriate subdivisions and scales of proportionate grading for the grading of every part of the garment. The template of the present invention comprises rectangular plate of appropriate dimensions and material, having two sides and a plurality of elongate apertures of variable length and direction, accompanied by metric subdivisions and scales of proportionate grading, and with other auxiliary designs which indicate the position of the grading points on a basic pattern block. The template of the present invention allows the grading of any garment pattern block, which includes thereon all of the required variations according to the internationally standardized sizes and be utilized for grading each of the different parts of a garment, with simplicity, certainly and absolute precision, in minimal time without geometry and complex calculations. GB-A-2151126 disclose a template for marking a basic pattern block for the manufacture of a garment and not to grading it proportionally from size to size for industrial purposes a procedure which is completely different. Another example the document FR-A-2396522 discloses a marking instrument consisting of a thin, flat sheet which is preferably transparent rigid, and polygonal in shape. The sheet is perforated to allow for a needle to pass through. The perforations are arranged so as to form concurrent straight lines joining in a zero point in the form of a central hole. The straight lines coinciding with the vertical and horizontal are emphasised. The X and Y axis coordinates have markings at the ends, indicating North, South, East and West. The present invention gives the opportunity to grade any garment part proportionally by keeping to the existing axes of the existing pattern block and using every time the appropriate increments (change from size to size) for each grading point. The Object of the invention is defined in Claims 1 and 4. Preferred embodiments of the invention are set out in dependent claims. The apertures with their appropriate subdivisions and grading scales are placed touching the basic points of any garment pattern block and the indication of their position is shown in projection on each of the auxiliary designs A,B,C,D,C,F, and G. A: Being the quarter front upper basic block B: Being the basic sleeve block C: Being the quarter back upper basic block D: Being the quarter front skirt E: Being the quarter front trouser block F: Being the quarter back skirt G: Being the quarter back trouser block. Scales X represent dart and notch grading points and features Z are designs of parts of a garment serving as an indication of where the grading of these blocks is effected. The present invention will now be described in relation to the accompanying drawings which illustrate a preferred embodiment of the present invention and the use of that preferred embodiment. In the drawings: Figure I is a plan view of a preferred embodiment of template in accordance with the present invention; and Figures II (1) to II(5) show the various steps in using the template of Figure I. Figure I illustrates a template 10 having a series of depictions of various parts of a pattern indicated as A,B,C,D,E,F,G. At various locations about those depictions are a plurality of apertures 12 (only given reference numerals in relation to depiction A) that include appropriate subdivisions and grading scales for the various international sizes. These apertures are located adjacent to the basic grading points of the depictions of the various parts of the garment. Also provided are various metric subdivisions 14 about the periphery of each of the various sections of the template 10 necessary for the adjustment and right angle placement of the template to the basic existing axes of the coordinates of the pattern block. Referring to the five stages of use of the template 10 as illustrated in Figure II,Figure II(1) shows the first stage of use. Prior to this stage, the pattern block of the basic initial size (for example,European size 46) which we want to grade (for example,front female bodice) is drawn on a sheet of paper,leaving ample space around it so that all the required graded sizes may be included thereon. The template is placed over the pattern block such that the point from which the first grading is to commence (for example,the waist point on the Centre Front (C.F.) of the bodice as illustrated in Figure II(1)) coincides with and touches the same point on the depiction A on the template 10. The template is set at a right angle to the basic axis of coordinates of the block and the corresponding aperture is used to mark on the block the line and the subdivisions given by the template. The template is then moved to the next point of grading on the initial pattern block(for example,the neck curve as illustrated in Figure II(2)) and again a right angle is formed with the axis of the coordinates of the basic pattern block. The line and its subdivisions are then marked through the corresponding aperture. The process is continued for the next point of grading on the initial pattern block (namely the neck point on the shoulder as illustrated in Figure II(3)) and the template is placed so that this point touches the aperture corresponding to the same point on the template and a right angle is formed as before. The line is then marked and the subdivisions are as given by the aperture. The same procedure is followed for the remaining points of grading as they appear on a model of the front bodice on the template (and as shown in Figures II(4) and II(5)) placing the corresponding apertures on the initial block and marking through them the lines and their subdivisions. Finally,the corresponding points of the subdivisions are joined together with straight lines and curves parallel to each other and to those of the initial block and there are then formed six blocks in total of proportionate sizes. Furthermore,and in a similar way,sizes may be downgraded beginning from a block of a large initial size and placing the template so that the largest subdivision of every aperture touches the corresponding point on the initial block. It will be appreciated that there may be other modifications and alterations to the configurations described herein that are also within the scope of the present invention, as defined in the appended claims.

Claims: A template for grading of existing pattern blocks of all parts and types of a garment, according to the international standardization of sizes, wherein said template is of rectangular shape having two faces, a front and back side, and a plurality of models of various basic garment pattern blocks which form together the parts of the garment, each of said models having a plurality of elongated apertures of variable length and direction, said elongated apertures being marked with size subdivisions and scales according to proportionate grading and positioned with respect to the coordinate axes of the existing pattern block, said template including at least one set of marked metric subdivisions for the adjustment and right angle placement of the template axes and the corresponding coordinate axes of the existing pattern block, said template further comprising auxiliary designs indicating the plurality of points to be graded on the existing pattern block. A template according to claim 1, characterized in that said elongated apertures are adjusted to the basic points of the existing pattern block of the garment and which show appropriate subdivisions and scales of size variation as they are required for every variation. A template according to claim 1, characterized in that each of said elongated apertures of variable length and direction represent dart and notch points to be graded. A method of constructing graded patterns utilizing said template as in claim 1, said method including the steps of: starting from an existing pattern block of a basic initial size to be upgraded or downgraded to desired predetermined sizes; placing said template upon said existing pattern block so that a template point from which the upgrading or downgrading begins matches an identical point on said existing block; placing said template in a corresponding position with the basic coordinate axes of the template and said pattern block aligned and marking in a corresponding aperture of said template a given line and a plurality of given subdivisions; repeating the previous steps for a plurality of points either to upgrade or downgrade said basic initial size; and joining said printed points on said existing pattern block and depicting said graded points of said pattern block in said predetermined size.
