Embodiment Construction

[0018] In Figures 1 and 2, numeral 1 designates as a whole a filter bag containing an infused product, such as tea, chamomile, or other herbal tea, which has a chamber 2 consisting of two separate sachets 3, each Charge 19 comprising infused product. The filter bag 1 is contained inside an outer wrapping or envelope 51 which encloses the filter bag 1 and protects its contents with respect to eg hygiene, smell, fragrance and other properties.

[0019] The filter bag 1 forming the subject of a prior patent application (IT BO2002A000013) filed by the applicant, is made of heat-sealable paper; has a thin wire portion 7 wound around the outside of the holding chamber 2, which is smaller than that of the holding chamber. Long in profile, the remaining length 8 of the thread is gathered and held between the surfaces 9a, 9b of the lifting label 6;

[0020] The plant 100 mainly comprises such a structure, distributed from left to right in Fig. 3, in the production line for carrying ou...

Abstract

An apparatus (200) for automatically and continuously forming envelopes (51) to contain filter bags (1) for an infusion product comprises: means (60; 129, 131) for forming the envelopes, designed to make on a web (126) of packaging material moving along a predetermined feed path (174) a longitudinal fold line delimiting two adjacent flaps (127) defining an interposed opening through which the web (126) can be laterally accessed by the filter bags (1); manipulating means (123, 148, 128) designed to receive the filter bags (1) in succession, to turn them so that they lie in substantially the same plane as the web flaps (127) and to move the filter bags (1) along a feed path (62a, 62b, 62c) having at least one end stretch (62c) that is substantially centred relative to the web flaps (127), the filter bags (1) moving along the stretch (62c) in the same direction as the paper web (126) before the manipulating means release the filter bags (1) between the web flaps (127).

Description

technical field [0001] The present invention relates to the automated production of filter bags, in particular filter paper, containing products such as tea, chamomile and similar herbs, which are designed to be submerged in liquids for infusion for various purposes, such as beverages or Dip for various medicinal purposes. [0002] In particular, the present invention relates to an apparatus for use in a continuous production process for the automatic formation of envelopes containing filter bags containing infusion products, if necessary, for hygienic purposes and for maintaining the odor and other characteristics of the infusion, and / Or to protect the filter bag itself, the envelope can be sealed. Background technique [0003] In the automated production of filter bags for soaking products, the preparation of the envelope and the insertion of the filter bag into the envelope are carried out by specific devices or units, which are known, namely: handling the envelope web...
