Manufacture of Pressure-Sensitive Products
Published in István Benedek, Mikhail M. Feldstein, Technology of Pressure-Sensitive Adhesives and Products, 2008
Confectioning includes mechanical processing by slitting, cutting, die-cutting, perforating, and embossing. The confectioning properties of the main PSPs were described in detail by Benedek in Ref. [54]. Confectioning requires roll and sheet material handling equipment, equipment for cutting in the machine direction (slitter) and cross-direction (cutter), sheeter and surface treating apparatus, die-cutting and embossing equipment, perforating equipment, and windowing and tag machines. Confectioning machines for labels cut, die-cut, punch, and perforate the web. The dimensions of the processed materials and their characteristics can vary widely. Thin films of 15–20 μm as well as thick paper (e.g., cardboard of 300 g/m2) can be processed.
Garment-on-Hanger Order-Fulfillment Operations

The next C-channel component is the die-cut hanger yoke. The hanger yoke is 3/8 inch thick and is welded to the end of the track at locations where there is a removable splice section. Depending on the manufacturer's installation standards, hanger yokes are used at various intermediate points to support the track. The hanger yoke straddles a track section and is welded to secure the hanger yoke to the track. Drilled holes connect two spliced track sections. At the track take-out station, the die-cut hanger yoke is part of the two track sections. This feature permits removal of the C-channel's take-out section from the track. This removed track section exposes the chain and permits the maintenance crew to observe chain travel over the C-channel.
Converting from Disposable to Returnable—Reusable Packaging
Published in Norman J. Crampton, Preventing Waste at the Source, 2018
Catalytic converter substrates are loaded in layers at Corning, with a die-cut foam pad between layers and a 1/4-mil HDPE tray, embossed with cavities to hold individual substrates. The tray also can be inverted as a cap, and it grips the foam pad cushion through a pattern of “buttons” in the tray that nest in a pattern of die- cut voids in the pad. This permits loads to be moved around the Corning plant without stretch-wrapping.
Preparation and characterization of low-cost waterproofing sheets from NR-loaded clay
Published in HBRC Journal, 2020
M.M. Abd El Kader, A.S. El Deeb
The samples used to perform experimental tests were prepared according to [ASTM C11361;99] with the recipe presented in Table 1. Mixing and mastication of all ingredients are conveniently done using two roll mills. The mixing operation was carried out in two stages. The first one called master batch consists of rubber, activators, antioxidant, antiozonants, reinforcing agent (clay as filler) and the amount of processed oil, 200 phr to assimilate high filler content and have optimum dispersion and coupling with rubber. The second stage is called the final batch. It consists of the previous master batch, curing agent (Sulfur and accelerators). These materials are added at the end of the process to prevent pre-vulcanization which may occur due to the elevated temperatures, the test specimens were die cut from test slabs. Vulcanization of the rubber compounds was carried out in an electrically heated uniaxial press between stainless steel plates at 150°C and pressure 150 bar for a certain time of 25 min. Samples were prepared by different shapes of molding according to the measurement types.
Strengthening and Widening of Steel Single Box Girder Bridge in Warsaw
Published in Structural Engineering International, 2019
Andrzej Kasprzak, Andrzej Berger
The scope of works performed within the bridge was as follows: Superstructure: examination of structural steel, disassembly of the die cut pieces of the slab and cantilever girders, installation of post-tensioning system, installation of the new braced cantilevers, application of anti-corrosive paint systems, test loads.Substructure: reconstruction of the abutments (demolition and construction of a new top plate, renovation and extension of the walls), execution of new coats of concrete pillars, replacement of bearings.Replacement of equipment including: asphalt pavement of the roadway and sidewalks, barriers and railings, drainage system and expansion joints.
Evaluation of vibrant muscles over the shoulder region among workers of the hand screen printing industry

EMG signals were recorded using the DataLOG SEMG system (Biometrics, UK) [27,28], which has eight independent programmable channels with about 20-kHz sampling rate per channel and an automatic anti-alias digital filter operating at approximately –3 dB at 0.45 × sampling rate and a maximum attenuation of –13 dB above 0.8 × sampling rate. The DataLOG system was interfaced to a laptop to control the system remotely. The SEMG sensor (SX230; Biometrics, UK) used for the study is an active probe with amplifier input impedance >10,000,000 MΩ. Because of the aforementioned input impedance, only a small amount of skin preparation is required and no conducting gels are necessary to acquire the EMG signals. This EMG sensor could just be placed on the muscle using die-cut, medical-grade, double-sided adhesive tape. A twin-axial goniometer (SG110; Biometrics, UK) was used to measure the angular movement of the trunk. It has an accuracy of ±2° measured over a range of ±90°; the repeatability of the goniometer is 1° measured over a range of 90° and the life of the goniometer is 600,000 cycles.
