Abstract: A process for the layout of wrappers for cigars in a half-leaf of tobacco, of the type in which the layout plan of the wrappers is set up by disposing them one by one on the half-leaf taking into account the real contour of said leaf and its possible blemishes, the wrappers being placed tangentially with respect to one another and/or to the contour of the half-leaf and/or to the possible blemishes.

Abstract: A process for laying out a maximum number of cigar wrappers in a leaf or half-leaf of tobacco, the position of each wrapper being located within the leaf or half-leaf by two series of variables which are, on the one hand, the abscissa or ordinate from the center of the wrapper plotted with respect to the main direction of the leaf and to one end of this leaf, and on the other hand the angle that the main direction of the wrapper makes with the main direction of the leaf, said process comprising the step of successively laying out the wrappers so that, for each wrapper, the abscissa, or ordinate, from the center or its angle with respect to the main direction is maximum or minimum.

Abstract: A wrapper distributing support band for the manufacture of cigars or similar products, wherein the "right" wrappers present a face of the tobacco leaf which is the reverse to that presented by the "left" wrappers.

Abstract: A method for mechanically wrapping closed tip cigars of the type in which the bunches are wound in the normal direction of the machine used when wrappers are to be employed which are cut out from a half-leaf corresponding to the "type" of the machine, i.e. "right-hand" or "left-hand", and said bunches are wound in the direction opposite said normal direction when wrappers are to be employed which are cut out from a half-leaf not corresponding to the type of the machine, wherein, in this latter case, a shaper is used for covering the tip of said bunches, which shaper has the characteristics of a shaper belonging to a machine of a type contrary to that of the machine used.

Abstract: A method for wrapping cigars or like articles in an outer envelope, or wrapper, made of natural tobacco, which comprises the steps of: at least partially spreading out a non-stripped tobacco leaf, cutting out a first batch of wrappers from one of the half-leaves on one side of the midrib, turning the leaf over onto its other face, spreading out the half-leaf which has not yet been cut out, cutting out a second batch of wrappers from this half-leaf, then rolling cigars or like articles in these two batches of wrappers, reversing the direction of rolling when passing from the wrappers of the first batch to those of the second batch.

Abstract: A process for the repetitive and optimalized layout of shapes having the determined contour of a cigar wrapper within each of the elements of a series of tobacco leaves or half-leaves (having an irregular shape and defects), with a view to cutting out and removing from said elements wrappers having said shapes, in which process at least one sample leaf is determined having dimensional characteristics inferior to those of the whole section of the series of the leaves to be cut out, then, for each of the sample leaves, cut out pattern cards are drawn up, each comprising the outline of a possibility, distinct from the others, of cutting a leaf similar to the sample leaf into said shapes of determined contour, wherein said pattern cards relating to the same sample leaf are graded into groups, as a function of their decreasing yield of wrappers, the pattern cards within the same group are graded as a function of at least one criterion other than that of yield and relative to the interest of use presented by said p
