K. LOHMANN DEVICE FOR CUTTING ENDLESS BANDS OF ARTIFICIAL FiBERS Filed NOV. 20, 1934 Afforneys Patented Jan. 3, 1939 UNITED STATES PATENT OFFICE DEVICE FOR CUTTING ENDLESS BANDS OF Karl Berlin-Treptow, Germany, assignor to I. G. Farbenindnstrie- Aktiengesellsehaft, H-ankfort-on-the-Main, Germany Application November 20, 1934, Serial No. 753,962 In Germany November 21, 1933 1 Claim. (01. 111-1) My present invention relates to cutting endless bands of. artificial fibers.
One of its objects is an improved process of producing a sliver of cut artificial fibers. Another object is a cutting device for producing the sliver of cut artificial fibers. Further objects will be .seen from the detailed specification following hereafter. Reference is made to the accompany s drawing in which Fig. 1 is aside view of the apparatus, Fig. 2 is a plan of the apparatus shown in Fig. 3 shows'a development of the surface of the cutting roller, which illustrates the i8 ment of the cutting blades. v
By means of this new cutting device it is possible to obtain a sliver which between the cutting and the drawing out device still retains a good union and after leaving the drawing out de- 90 vice is characterized by a particularly good union of the individual fibers.
Freshly produced bands consisting of endless parallel artificial fibers have been dry-crimped in direct sequence to their manufacture or after arrangetheproductionofaspinninghanlrinasingle operationandhavethenbeencuttostaples, that isto say,intolengths ofasiseaccordingtorquirement and drawn to produce a new band; the band of fibers is subdivided by cuts which 30 extend over the whole breadth of the band. Artificial fiber bands have been cut by means of arotating knife roller which also makes the cut co-extensive with the breadth of the band.
The present invention relates to the produc- 85 tion of aband of cut artificialfibers, having an essentially improved union of the fibers, by subdividing the hitherto usual complete cut into partial cuts, which are so distributedcnthebandofendlessartificialfibersto 40 be cutthat' the sliver is subdivided by the cuts in such a manner that it is impossible for an uncut endless fiber to pass through the cutting device.
The invention consists in a rotary cutter having cutting blades in compound at. 4 'lhebladesmaybearrangedonthecylindrical surface of the roller in such a manner that either the whole sliver is subdivided into pieces of equal length or into pieces of periodically recurring lengths. This is attained in the first case .by a uniform arrangement of the blades and in the 8 second case by an irregular arrangement of the blades on the cylindrical surface. This cutting roller has a double function. It servesas a roller for feeding the band and also as a cutting roller. For these two functions it is necessary that the 10 surface between the blades should consist of rubher or the like. As a counter-support for the cutting roller there may be used either a roller having an elastic surface or, a table having an elastic cover. It is essential that the support should move at the peripheral speed of the cutting roller.
In Fig. 1 the band 1 to be cut passes between the feed rollers 2, 3 and is then subjected to the cutting operation between the cutting roller. I carrying the knives i and the elastic coating 8.
The supporting roller is shown at I. The'band is then engaged by a pair of draft rollers- I and drawn through the drawing out device Qln the formof a gill box with single set of fallers by meansofasecond'pairofdraftrollers ll.
Fig.2 showsaplanviewot thatpartofthe device below theilber band I.
Fig. 3 shows an arrangement of cutting blades on the cutting roller according to this invention.
What I claim is:
In a device for cutting to static lengths endless bundles of rayon fibers without the application of any considerable tension. in combination a cutting roller having a surface made of resilient material carrying a series of blades, said blades being so arranged in staggered relation as to cover the whole breadth of said cutting roller,
a supporting means having a resilient surface pressing said endless rayon bundle against said cutting roller, said supporting means being moved at a speed identical with the peripheral speed oi said cutting roller.
