摘要:
Device for the formation of a package (4) of envelopes (1), vertically juxtaposed and stacked, said package comprising a front cover (2) and a back cover (2), both of a size equivalent to the size of the envelopes to be packed, and at least one wrapping strip (3) holding both covers and the envelopes included in the package, said covers presenting, in their upper and lower edges, homologous attaching means (21, 22) coupled with tongue and groove in the stacking of the packages and the wrapping strip or strips being placed in a vertical plane that holds the upper and lower edges of the envelopes between the front and back covers.
摘要:
Flat envelope, of the type having a rear surface (2), a front surface (1) and a closing flap (3), both the front and rear surfaces having two side flaps (4-5) separated by two "V"-shaped cuts (C1 a and C1 b), the vertices of which coincide with the transverse line (L1) that separates the rear and front surfaces, and with the corresponding side line (L3). The flaps (5a and 5b) have two cuts (C2a and C2b) affecting the areas corresponding to the free ends, next to the mouth of the envelope, that have a length at least equivalent to the sides of the flap (3), such that when making up the envelope it is located on top of said cuts; in such a way that the sides of the envelope have a uniform thickness along their entire length since they are formed by the same number of overlapping paper surfaces.
