Abstract: A branched stent includes a main branch having a tubular main lumen and a side branch that branches off from the main branch. The main branch and the side branch are made from a strand-shaped starting material. The side branch is configurable between a first state in which the side branch lies within the main lumen and a second state in which the side lies outside the main lumen. In the second state, the side branch defines a tubular side branch fluidically connected to the main lumen. The side branch is formed at least in part of a shape-memory material.

Abstract: A loop structure includes a first element having a first loop, and a second element having a second loop, the first loop interlocking with the second loop. Each of the first and second elements include a plurality of strands, wherein at least a portion of the strands are formed from a flexible material. The strands of the first and second elements are processed in a textile-like manner into one of a braided, woven, knitted, or enmeshed structure defining at least two webs spaced-apart along a longitudinal direction of the first and second elements. The strands are divided into longitudinally extending sections between the webs, the sections forming wings that connect the webs. In the first element, the wings form the first loop, and in the second element, the wings form the second loop.

Abstract: A braided structure and associated method of making include a primary limb braided from a group of filaments and at least two secondary limbs. Each secondary limb is braided from filaments, wherein a totality of the filaments associated with the secondary limbs is the same as the group of filaments of the primary limb. A transitional region is braided from the group of filaments of the primary limb formed between the primary limb and the secondary limbs.

Abstract: The invention relates to a bifurcated stent (1) made of strand-shaped starting material, in particular of threads and/or wires (9), comprising a main branch (2), which includes an essentially tubular main lumen (4), and a side branch (3), which branches off from the main branch (2), wherein the side branch (3) can be transferred from a first state, in which the side branch (3) lies at least partially, preferably completely, inside the main lumen (4), into a second state, in which the side branch (3) lies outside the main lumen (4), wherein the side branch (3) in the second state comprises an essentially tubular side branch lumen (6), which is fluidically connected to the main lumen (4). According to the invention, the side branch (3) comprises a shape-memory material.

Abstract: This invention relates to a loop structure (7) comprising at least two elements (1), wherein each element (1) comprises at least one loop (5) that interlocks with at least one loop (5) of an additional element (1). In accordance with the invention, it is proposed that each of the elements (1) has a multiple number of strands (2), at least partially made of flexible material, wherein the strands (2) of the element (1) are processed in a textile-like manner into at least two webs that are spaced apart from each other in the longitudinal direction of the element (1); in particular, they are braided, woven, knitted and/or enmeshed, and the strands (2) are divided into sections and each part is processed in a textile-like manner into a wing (4), wherein at least two wings (4) connect two of the webs (3) to each other and the loops (5) are formed from the wings (4). Furthermore, the invention relates to a method for producing a loop structure (7) as described above and an element (1) that has a loop (5).

Abstract: The invention relates to a textile machine comprising a sliver channel (2) arranged in a rotating plate (1) for a cycloid-shaped deposit of a fiber sliver in a can. The sliver channel (2) is characterized in that the cross-section thereof is divided into a guiding cross-section (4) and a remaining cross-section (5). The invention also relates to a method for guiding a fiber sliver within a sliver channel (2), characterized in that the tensioning of the fiber sliver is such that the fiber sliver extends in a guiding cross-section (4) in the sliver channel (2).

Abstract: A process for the level adjustment of the can plate of a sliver can is proposed which is in a filling position at the output of a textile machine to be filled with fiber sliver F. The can plate is moved before the start of the filling process by a first moving device from a lower can plate position into a higher can plate position and is moved into the lower can plate position during the filling of the sliver can. The process according to the invention is characterized in that the can plate is moved before the start or during the starting phase of the filling process by a second moving device from the higher can plate position into an upper filling position after the sliver can enters a position to accept sliver from the textile machine. Furthermore, a suitable apparatus to perform the process is presented.

Abstract: For the stretching of textile fibers, a new process is proposed, wherein a portion of the necessary force for stretching is exerted by at least one fluid (7), which is brought into contact with the fibers to be stretched in such a manner, that the said fluid (7) entrains the fibers (6) and brings to bear at least a portion of the necessary tensile force for the stretching thereof. The apparatus for the stretching of textile fibers includes a stretch chamber (1) in which the fibers are stretched, wherein an inlet apparatus (11) is located for the injection of at least one fluid (7) to fibers (6) being transported within said stretch chamber (1) and said inlet apparatus, together with the stretch chamber (1), is so constructed that the added fluid (7) imparts the necessary tensile force for the stretching to at least a portion of the fibers (6).

Abstract: A process for the level adjustment of the can plate (14) of a spinning can (10, 100) is proposed which is in a filling position at the output of a textile machine to be filled with fiber sliver F, whereby the can plate (14) is moved before the start of the filling process by a first moving device 17 from a lower can plate position into a higher can plate position and is moved into the lower can plate position during the filling of the spinning can (10, 100). The process according to the invention is characterized in that the can plate (14) is moved before the start or during the starting phase of the filling process by a second moving device (9; 109) from the higher can plate position into an upper filling position as the spinning can (10, 100) is in filling position. Furthermore a suitable apparatus is presented.

Abstract: Upon filling cans with fiber band, the movable bottom of the cans, as the filling process proceeds, moves downwardly from an initial upper to a lower final position. As this happens, between two elements, one inside, one outside the circumferential shell of the can, a force field is built up in such a way that the element inside the can supports the can bottom and because of the force field, this bottom is held at the same elevation as the element outside of the can. Further, the desired operating height of the can bottom can be correspondingly held. For the lowering of the can bottom, one of the two elements between which the force field exists, is moved relative to the other in the direction of the lower final positioning of the can bottom and the remaining element follows after, because of said force field, until both elements again stand across from one another at the same height.
