- the structure (35) is supported by means of two blocks (37) and (60) which in turn are attached to the bases of the former (39) and (61), these bases are attached to the supports (43 ) (47) (65) and (68) by means of spacer blocks (41) (49) (63) and (70) the block (37) is attached to the support (39) and the structure (35) by by means of two rotating screws (36) and (38), the block (60) is connected to the structure (35) and to the support (61) by means of rotating screws (58) and (59), the blocks ( 37) and (60) serve to be able to keep the entire formation unit together in such a way that when it is required to change the formation fabric (72) they are only removed and the entire unit remains in cantilever allowing the installation of the new fabric to be done in the minimum time.
- the support (39) that is immediately below the support roller is attached to the bases (43) and (47) by means of spacers (41) and (49) that are held by screws (40) and (50)
- the support (61) that is immediately below the chest roller is attached to the bases (65) and (68) by means of spacers (63) and (70) these supports are held fastened by means of screws ( 62) and (71),
- the equipment of the present invention has a system of slices (45), (46) and (66) that allow the unit to rest on the rails (44) and (67) when removing the spacer blocks (63) (70) ( 49) and (41), this allows the unit to be completely removed from the machine without stopping the production process.
- This unit has a position control system of the plastic forming fabric (72) by means of a guide roller (51)
- the mechanism for operating this guide roller is as follows, the guide roller (51) is supported by means of a bearing (57), this bearing is connected to a support plate (56) which is operated by two pneumatic bellows (54) (55), the support plate (56) is held in position by means of a slice (52 ) and (53), these slices maintain the horizontal and vertical position of the support plate, the pneumatic bellows (54) and (55) adjust the position of the guide roller (51) by varying the pneumatic pressure in each of them.
- This equipment consists of a forming roller (82), this roller is attached to the structure (35) by means of screws (101) that fix to the bearing (83) where the forming roller rotates.
- This forming roller is constructed with a steel core (138) which is coated with a resin (82) whose surface is machined to give it an aerodynamic profile (139), which allows to generate a positive pulse in the first contact with the fabric and another negative pulse at the time that this profile ceases to be in contact with the plastic forming fabric, the peripheral speed of the roller is lower than that of the forming fabric allowing a water injection from the bottom of the fabric to the top where the fibrous suspension is, this causes a rearrangement in fiber dispersion.
- the chest roller (97) rotates on bearings that are housed in a bearing block (98), which is attached to the structure (35) by means of screws (99) and (100) the position of the chest roller it is adjusted with a spindle (91) which by means of nuts (95) and (96) adjusts its position.
- the spindle (91) is attached to a structure (88) that also supports the base of the forming blades (86) this base is attached to the structure (88) by means of a thyme (87).
- the base of the forming blades adjusts their position against the chest roller by means of a spindle (92) and fixing nuts (93) and (94) the structure
- This training equipment has a flow distribution box, which is composed of a conical manifold (121) whose function is to distribute the fibrous suspension flow uniformly across the formation unit. Attached to this conical manifold is a stepped diffuser (114) by means of a throat (117), the stepped diffuser seals in its lower and upper part by means of a plastic tube (118). To avoid bending the stepped diffuser, there is a plate (115) that completely covers it. This plate is connected to the manifold and to the top of the distribution box by means of screws (119) and (120). The main function of the step diffuser is to keep the fibers in a complete state of dispersion.
- the distribution box has a lower lip (109) and an upper activity lip (108), the upper lip adjusts its opening position to control the discharge flow by means of screws (122) that are at the ends of the distribution box, the profile of the box is adjusted by means of other screws (104) that are inside the distribution box, in both cases the screws are adjusted by means of fixing nuts (106) and (104 ), the internal (104) and external (122) screws are attached to a bridge (105) that allows the movement of the lip to be uniform.
- the upper activity lip (108) has a label (110) which is supported on a plate (112) and a fixing unit (111) this allows the upper activity lip (108) to move freely without leaking fibrous suspension.
- the upper activity lip at its discharge end has a profile that is designed to create activity in the fibrous suspension and to be able to orient the fiber in high concentrations, also allows to obtain a paper of lower density, this profile is composed of an inclined part ( 136) and a straight part (135) that cause the flow of the fibrous suspension to have a speed change in the horizontal and vertical part.
- the activity profile is spaced across the box distribution by means of sectors (137) that retain the same thickness of the upper lip, the hydraulic pattern generated internally by the upper activity lip causes cross-flow on the formation table when leaving the fibrous suspension the distribution box. This causes the fibrous orientation in the transverse direction to be improved, that is, that the ratio of fiber orientation in the machine direction between the fiber orientation in the transverse direction decreases. With this it is achieved that the values of the physical properties of the paper in a transverse direction tend to be similar to those of the machine sense.
