Description

Przedmiotem niniejszego wynalazku jest sposób wyrobu grzebieni metalowych, wyrózniajacy sie od dotychczas stoso¬ wanych sposobów prostota, , oszczed¬ noscia czasu i materjalu.Na zalaczonym rysunku na fig. 1-w widoku i na fig. 2-5 w przekroju podlug linji A-B fig. 1 przedstawione sa rozmai¬ te stadja wyrobu grzebienia wedlug ni¬ niejszego wynalazku.' Na odpowiedniej wielkosci kawalku blachy a wycina sie zeby b-bn, których ilosc zalezy od pozadanej dlugosci grze¬ bienia i które maja podwójna dlugosc, w stosunku do zebów w skonczonym grzebieniu, poczem cala blache zgina sie wzdluz .linji C~D, przechodzacej przez srodek wyciec. Blacha a jest u obu konców zaopatrzona w wygiecia c, cu w" które wsuwa sie w ten sam sposób sporza¬ dzona druga blache d, stanowiaca druga czesc grzebienia swemi wygieciami e-elt poczem obie czesci zostaja przez naci¬ sniecie sztanca albo w podobny sposób nawzajem do siebie przymocowane. PL PLThe subject of the present invention is a method of manufacturing metal combs, which differs from previously used methods in simplicity, time saving and material. The attached drawing in Fig. 1 is a view and in Figs. 2-5 in section along line AB 1 shows various stages of making a comb according to the present invention. On the appropriate size of a piece of sheet metal a, the teeth of the b-bn are cut, the number of which depends on the desired length of the comb and which are twice as long as the teeth in the finished comb, then the entire sheet is bent along the C ~ D line passing through leak out. The sheet a is provided at both ends with bends c, which are inserted in the same way, the second sheet d, which is the second part of the comb, with its bends e-elt, then both parts are pressed by pressing a die or in a similar way attached to each other PL PL

Claims

1. Patent claim. The method of manufacturing metal combs, consisting of two separate parts (aid), the main characteristic is that in the pieces of metal sheet (a, d) forming part of the comb, holes are cut in any number, double to the teeth of the comb lengths, then the sheets are bent along a line passing through the center of the holes (c, cv e, ex), then they are inserted into each other in the bends and allowed to punch or in any other way.
