Description

Circulation softening machine (softener) for hemp, jute and other plant fibers The invention relates to a cycle soft machine (Softener), in which the Hemp or other vegetable fibers in the cycle once or several times, depending on the desired Degree of machining, run by the machine with no additional operator required than is necessary to place and remove the work item.

There are already circuit soft machines of other types known, and in Figs. 1, 2 and 2a such is illustrated in elevation and plan. These usually consist of two soft machines (S1 and S2) set up side by side in opposite directions, which are connected to one another by an arched roller table R (Fig. 2) or by longitudinal and transverse slat tables Ll, L2 and L3 (Fig. 2a). The work item placed on the support table la (Fig. I) runs through the row of rollers i and at the end of the same reaches the rollers r of the roller table R (Fig. A), which feed it to the second row of rollers k. After passing through the same, the work item is removed from the discharge table i. If the product has not yet softened sufficiently and is to be circulated a second time, it must be brought from the discharge table i to the infeed table h by hand.

The main deficiency of the arrangement according to Figs. I, 2 and 2a is that that the machine system takes up a lot of space. Also, there are at least two Workers needed to work on the roller table R or on the slat tables L1, L, and L3 with it are busy setting up the work goods and falling down at the bend or prevent at the turning points. The arched roller table R for transferring the work material from the first to the second soft machine has the disadvantage that the work piece, which is placed on the support table k parallel to the grain direction and has run through the row of rollers i in an orderly manner, in the curve by the change of direction gets into disorder, from which it naturally suffers. If instead of the roller table If a transverse conveyor belt is arranged (see Fig.2a), this situation occurs to an even greater extent than that which emerges in the form of a ribbon from the row of rollers i Work goods are placed on the conveyor belt running transversely to the direction of work L. is agglomerated and comes in the form of an elongated bead on the Work table L3, which in turn is arranged and arranged according to the grain direction and distributed must become.

All of these deficiencies are eliminated with the new machine. The space requirement for this is about a third of the previous one, which when comparing Fig. q. and 2 is readily apparent. The work piece arrives parallel to the fiber from the feed table a (Fig. 3 and q.) in the form of an uninterrupted belt through the first row of rollers h and the diverting rollers c, which can be designed as work rollers, to the second Roller row d and, when this has been run through, in the same form through the double Discharge table e out of the machine.

If the discharge table e is brought into the dotted position f, then the work goods in an orderly condition, again in the form of a band, on the support table a automatically applied for renewed circulation. Except for laying up and No operation is required to remove the work item. The cycle within the The machine does not require any supervision.

The removal table e, because of its steep working position in the position f is designed as a double conveyor belt, z. B. by a crank mechanism be pivoted about the axis m and thus reaches the position f g is also pivotable about point n and is before lowering the discharge table folded up into position f.

Claims (3)

PATENT APPLICATION: i. Circulation softening machine (softener) for hemp, jute and other plant fibers, characterized in that the work material from an infeed table (a) after passing through a first row of corrugated rollers (b) through conveyor rollers (c) connected to these rollers is above a second is fed to the first row of rollers (d), runs through it and, after passing over a removal table (e) above the infeed table (a), leaves the machine or is brought to rest again on the infeed table (a) in the case of repeated processing. 2. Machine according to claim i, characterized in that the conveyor rollers (c) are designed as work rolls from the lower row of rolls to the upper row. 3. Machine according to claims i and 2, characterized in that the removal table (e) is arranged at the end of the upper row of rollers so as to be pivotable about an axis (m).
