摘要:
A cloth cutting system wherein cloth is carried in a single layer into a cutting area wherein a laser beam is focused on the cloth and is directed by computer commands to travel within the cutting area so as to cut a plurality of patterns through the cloth rapidly and accurately.
摘要:
The present invention relates to a procedure for optimizing the processing of cutting material, such as textiles, leather and technical fabrics and the like, as well as to a device to perform the procedure. The cutting patterns (T1, T2, T3) are first contained in the main memory of a computer (1) and then are selected. The selected patterns are projected on a cutting material on a working surface (AF) in their original size by means of direct laser projection, possibly with different colors, and are also projected on a control panel (4) in a scaled down size. The laser projections of the individual patterns are then interlocked on the cutting material by means of a control unit (5) actuated by an operator (P) positioned next to the cutting material. The patterns are interlocked to optimize use of the cutting material by accounting for the conditions of the cutting material, such as defective spots (F1, F2, F3, F4), and the shape of the cutting material. Once the patterns are finally positioned, data on these positions is then transmitted to a cutting unit, such as an automated cutter (C), by an instruction given by the operator and the citing operation is triggered.
摘要:
An automated cutting and kitting system for preimpregnated composite material and method by which a layup of a plurality of plies of at least two types of preimpregnated composite material is cut and stored. Each ply of a given type of preimpregnated composite material is aligned in the order in which it is positioned in the layup, cut in accordance with a predetermined shape and stored such that the top ply in the layup is stored first. The different types of preimpregnated composite material are supported on a supply which is indexed to present the particular type of material required by the layup.
摘要:
A supporting bed for supporting a stack of sheet material in a cutting machine of the type retaining the material by means of a vacuum applied from below the supporting bed is manufactured from a composite structure of starting material including individual layers of reticulated foam material separated by at least one layer of a hot melt adhesive web. The composite structure is compressed under heat and pressure so as to be permanently reduced to approximately 10-35% of its initial thickness. The degree of compression, the temperature and compression time, and the porosity of the retriculated polyurethane foam starting material are selected to provide particular airflow and firmness characteristics for the finished supporting bed.

A supporting bed for supporting a stack of sheet material in a cutting machine of the type retaining the material by means of a vacuum applied from below the supporting bed is manufactured from a sheet of reticulated polyurethane foam material which has been compressed under heat and pressure so as to be permanently reduced to approximtely 10-35% of its initial thickness. The degree of compression, the temperature and compression time, and the porosity of the reticulated polyurethane foam starting material are selected to provide particular airflow and firmness characteristics for the finished supporting bed. In a preferred embodiment of the invention, the starting material is a reticulated grafted polyether foam having a porosity of 30 pores per inch and a sheet thickness of 5 inches. The sheet of material is compressed to a thickness of one inch and retained under pressure for 10 minutes at a temperature of about 400.degree. F.
摘要:
A method and apparatus for forming a composite filler is presented. The method comprises cutting a number of layers from a composite material. The method also aligns the number of layers to form a composite filler having a cross-sectional shape. Each of the number of layers has fibers in plane with the cross-sectional shape.
摘要:
A vehicle interior panel (10) includes a decorative covering (16) with a non-visible tear seam that forms a deployment opening through the covering during airbag deployment. The tear seam is formed by mechanical piercing of a skin layer (20) of the covering using a piercing tool (30) having a compound chamfer (40). Such piercing tools allow the mechanical piercing process to produce non-visible and functional tear seams in polymeric materials and non-polymeric materials such as leather, including materials with relatively low elastic recovery characteristics. Tear seams formed in this manner can offer larger processing windows, lower manufacturing and equipment cost, and/or shorter cycle times when compared to other methods such as laser scoring.
摘要:
A process for reproducing a design, especially a fabric design comprising an embroidered applique element stitched to a base fabric material, comprises the sequential steps of analyzing the design to derive data for use as stitch command data by an embroidery machine, and as cutting command data by a cutting machine, cutting out an applique element from a sheet material in accordance with the cutting command data, transferring the cut-out applique element to the base material and stitching the applique element to a base material in accordance with the stitch command data. The invention provides a far quicker, more accurate and neater embroidered applique fabric than prior semi-manual techniques.
