Description

Method and device for manufacturing sensitive elements

  The present invention relates to a method for manufacturing substantially cylindrical elements forming plants, each consisting of an envelope surrounding particles of filling material and possibly at least one seed, by continuously bringing a ribbon of material forming an envelope and continuously feeding particles of filling material and possibly

  seeds to the ribbon of material forming an envelope, the particu-

  the fillers being taken from a re-

  serve and these individual particles being continuously spread so as to form a thin layer (veil) whose

  height is small compared to the transverse width

  the to the direction of transport, and the particles of material

  re filling constituting the veil being collected so as to form a narrow bead of filling material,

  which cord is transported transversely to the direction

  tion of transport of the veil and in the direction of its own longitudinal axis, then is wrapped with a ribbon of material forming an envelope and thus transformed into a rod from which the elements forming plants are obtained

by cutting.

  The invention further relates to a device which,

  intended for the manufacture of substantially cylindrical elements

  ques forming plants each consisting of an envelope surrounding particles of filler material and possibly at least one seed, comprises a mechanism for feeding a ribbon of material forming an envelope, a

  mechanism for feeding particles of filling material

  pleating and optionally a mechanism for feeding seeds, the mechanism for feeding particles of filling material having the form of a device

  spreader intended to continuously sample particles

  fill with filling material and spread the filling material in the form of a thin layer (veil), the height of which is small compared to the width transverse to the direction of transport, to which the latter feed mechanism follows a

  cord conveyor which, guided transversely to the di-

  rection of transport of the veil and intended to pick up the material

  filling filler constituting the veil so as to form a narrow bead of filling material, continuously brings the bead of filling material to a device

  intended to form a flange and to a cutting device intended

  born to separate elements forming plants from the sausage by section

  weaving. By "filling material" here is meant material in which seeds can, at least

  for a while germinate and develop roots.

  By "continuously" is meant in particular

  "continuous", although the term also includes inter-

  endlessly succeeding time slots.

  The main patent had as its subject: - a process for manufacturing elements which are substantially

  cylindrical forming plants, each consisting of an envelope

  loppe surrounding the filling material and possibly-

  at least one seed, by continuously feeding a ribbon of envelope material and by continuously supplying filler material and possibly seeds to the ribbon of envelope material, the filler material

  being taken from a reserve and its individual particles-

  being continuously spread out so as to form a

  thin che (veil) whose height is small compared to the width transverse to the direction of transport, and the filling material constituting the veil is collected so as to form a narrow bead of filling material, which bead is transported transversely to the direction of transport of the web and in the direction of its own longitudinal axis, then is wrapped with a ribbon of material forming an envelope and thus transformed into a rod from which

  the elements forming plants are obtained by cutting,

  characterized in that from the reserve are drawn cons

  continuously, as a filling material, artificially produced fibers, which are spread in the form of a thin layer (veil) and then continuously collected so as to obtain the narrow bead of fibers forming a filling material; and a device which, intended for the production of substantially cylindrical elements forming plants, each consisting of an envelope surrounding the filling material and optionally at least one seed, comprises a mechanism for feeding a ribbon of material forming an envelope. , a

  mechanism for supplying filling material and event

  a mechanism for feeding seeds, mechanically

  me for the supply of filling material having the form-

  me of a spreading device intended to continuously sample-

  particles of filler material on a re-

  serve as filling material and spread the filling material in the form of a thin layer (veil), of which

  the height is small compared to the transverse width

  dirty to the direction of transport, to which the last feeding mechanism follows a cord conveyor which, guided

  transversely to the direction of transport of the veil and

  tiné to pick up the filling material constituting the

  veil so as to form a narrow bead of filling material

  pleating, brings the bead of filling material

  nuately to a device intended to form a sausage and to a cutting device intended to separate elements forming plants from the sausage by cutting, characterized in that the

  filling material reserve is essential

  by artificially made fibers.

  This addition concerns a modification of the process.

  die and device according to the main patent with the aim of making it possible to manufacture under better conditions, in particular in an economically more advantageous manner,

  elements forming plants of the genus mentioned above.

  According to the invention this object is achieved by the fact that on

  the reserve are withdrawn continuously, as a ma-

  filling, particles of artificially produced foam material which are spread out under the

  form a thin layer (veil) and then collected conti-

  only so as to obtain the narrow bead of filling material. By "narrow" bead of filler it

  should hear a bead that is significantly higher

  troit that the width of the veil measured transversely to the

  transport direction thereof; advantageously, the cor-

  don is only slightly wider than the diameter of the bou-

  din to be divided into elements forming plants.

  The device mentioned above is characterized according to

  the invention by the fact that the reserve of filling material

  sage contains particles of alveolar matter artificially produced.

  Both for the process and for the device according to the

  vention, the particles of cellular material produced ar-

  tificially can consist of resin

  expanded phenol-formaldehyde or urea-formaldehyde resin

  expanded hyde; particles of polystyrene foam or polyurethane foam are also suitable (for example

  diphenylmethane diisocyanate / polyether polyol base).

  The invention also relates in particular to elements for-

  mant plants produced by the process according to the invention; these

  elements include an envelope in a sensitive form

  cylindrical and a body formed of filling material

  wise; if necessary, the filling material contains at least

  a seed. The plant-forming element according to the invention is

  characterized in that the filling material is made up

  by particles of alveolar synthetic material or

  holds such particles. Particles of cellular material

  the artificially produced laire can be constituted by expanded phenol-formaldehyde resin or by expanded urea-formaldehyde resin. Also agree

  particles of polystyrene foam or polyurea foam

  thane (for example based on diphenylmethane diisocyanate / polyether polyol. The individualization of the particles of cellular material

  re artificially made by trans-

  férer those, while reducing their degree of compaction, from a large reserve to a smaller reserve kept constant, on which the particles are removed by means of needles or points and are then spread out in a thin layer (veil ), can be done advantageously

as in the main patent.

  It is the same for the formation of a cord of ma-

  filling filler to which are eventually brought

  periodically from the seeds, and for the operation consisting in wrapping this cord with the ribbon of material forming an envelope

  in order to form a sausage to be divided into elements forming plants.

  Finally, obtaining the elements forming individual plants

  duels, whether or not with seeds, by cutting and their

  transport can be carried out as in the main patent.

  Regarding the technique and methods of implementation

  work, we refer to the main patent (detailed description-

  yarn and drawings), the artificially made fibers of it (referenced 3 in this patent) being replaced by

  particles of artificial fabricated cellular material-

lement.
