Measurements
Step 1: Preparation
Before starting measurements, make sure the measurer is wearing proper protective gear: a helmet, safety glasses, steel-toe shoes, and a work overall.
Ensure that the area around the installation site is accessible.
Gather all necessary measuring tools such as a tablet, tape measure, square, as well as a pen and a drawing template (if needed).
Step 2: Determine the dimensions
Measure the object starting from the center and moving outward to capture the shape of the future mattress in its unfolded form on the measurement drawing. If you’re sketching what you see directly, note it as a “view” without mirroring (though it’s better to reflect it horizontally).
Measure the length, width, and height of the object for which the mattress will be made.
Record these measurements accurately in the measurement drawing.
Step 3: Check for special details
Check for any special features such as holes, fasteners, cutouts, hard-to-reach areas (hereafter referred to as DD), or other complex shapes that need to be included in the mattress.
Record these details. Note the size of each hole (pipe, fastener, etc.) and the distance from the center of the hole to the edge of the intended mattress — whether from the top, bottom, right, or left side (write these measurements in the section of the mattress corresponding to the edge from which you measured).
Step 4: Document and verify
Thoroughly document all collected data. Verify the accuracy of all measurements before proceeding. Assign a unique number to each mattress and write it on the drawings and on the pipe (unit, pump, etc.) so you know exactly which mattress goes where after manufacturing.
Step 5: Data processing
All dimensions on the drawings are given without allowances, so you need to add them according to Table 1.
Write the adjustments (values with added allowances) in red — these are required to ensure the mattress fits perfectly.
Step 6: Quality control and data transfer
Perform a final accuracy check of all measurements.
Print the drawings and transfer them to the design department.
Instructions for the allowance table for net measurements
Used when creating drawings with allowances
This table is intended for calculating allowances to the net dimensions of pipes, equipment, and units, taking into account filling and compression during the assembly of the finished product with straps. The table presents the main parameters that must be considered when creating high-quality drawings with allowances.
Table Parameters:
1. Net circumference (in cm):
The circumference values are indicated without filler.
2. Circumference with filler (in cm): The circumference values are indicated including filler: 50mm; 60mm.
3. Height (in cm): The net height of the object is indicated.
4. Height with filler (cm):
The height of the mattress with 50mm filler is indicated.
The height of the mattress with 50mm filler is indicated.
Important note:
For circumferences exceeding 101 cm and heights exceeding 80 cm, special calculation rules apply. In this case, special formulas are used, which must be taken into account when calculating allowances.
Application:
1. Determine the net circumference and height of the object.
2. Select the appropriate filler value (50mm or 60mm).
3. Write the corresponding values in the drawings with allowances in red.
This instruction will help you correctly use the table to calculate mattress dimensions, taking into account all necessary parameters and conditions.
