Technological Features Production of Editions, Which Have Variable Elements in Structure ; Технологические особенности изготовления изданий со сменными элементами блока ; Технологічні особливості виготовлення видань зі змінними елементами блоку

According to the results of the previous studies, the most popular designs of editions with variable elements were selected, namely: binding with rings, metal holders, elastics, with a plastic disk, editions with magnetic core, editions with a rod, with a syringe, with an origami fastener system and the results of the analysis of the advantages and disadvantages of such publications are presented.In addition to the general advantage for all these constructions, that is, changes in the elements of the block, the following benefits are also highlighted: change order notebooks; quick attachment/disconnection of items; interactive use; and disadvantages: limited volume of variable elements; rapid wear of origami fasteners; complexity of execution of manual operations; for designs with magnetic core — attach of extra metallic objects that are within the limits of magnetic influence; for the designs with a wooden rod — the loss of the main element (rod) leads to the destruction of the entire structure.Binding operations for the issue of this type of publications were analyzed, their block diagrams were developed. According to the developed block diagrams of the brochure-binding technological processes of editions with variable elements, the number of manual operations in the post-print stage were analyzed. The largest number of manual operations requires the edition with magnetic core. Since the number of manual operations does not always correlate with time for their execution, calculations of the duration of manual operations are performed. Were found, that the longest time need for edition with fastening on metal holders and the system of origami fasteners, the smallest — with a ring attachment and a wooden rod.According to the research results, the total time for the execution of printing and postprinting processes for each type of designs were determined. Also, were established how much longer the manufacture of these structures is compared with the manufacture of a publication in a type 7 binding cover. ; По ...
