摘要:
The apparatus comprises a carousel (1), rotatable about a central axis (2) with respect to a base frame (3). To the carousel (1) many couples of forms (4 and 4') are connected, cantilever mounted, which follow a circular trajectory indicated as dotted line. The couples of forms (4 and 4') can be arranged, radially or parallel to each other, on the carousel substantially according to the sides of a polygon. The forms have anatomical shape like a leg with foot end and are stiff enough from staying vertical oriented towards the above. The carousel moves through a loading station (5) of the stockings on the forms (4,4'), a station (6) for stretching the stockings on the forms; a steaming station (7), for steaming the stockings; an air drying station (8) and an outlet station (9) of the finished articles. At each station of the carousel the tights present on the couples of forms (4 and 4') are treated at the same time or in turn. The carousel (1) comprises a tubular body (10) having a prismatic wall (11), pivotally connected to the base frame (3). The wall (11) has the main function of rotating, and then to be the frame of the carousel (1), and it holds also radially the forms (4) arranged as cantilevers so that they do not extend from the bases. A steaming chamber (20,20') is provided that can move from an open position that allows the free rotation of the forms (4,4') to a closed position that embraces completely both couples of forms (4,4') sealingly contacts the wall (11).
摘要:
A method for longitudinal orientation of tubular knitted elements such as socks (2), knee socks or the like, wherein a stretching step of the sock (2) is provided in a duct (3) of orientation with its two ends aligned longitudinally. Then the position of an end that is either a tip portion (2') or a band portion is detected by means of sensors (13). At the detecting step the sock (2) is conveyed in the duct (3) in a direction according to which the position is known of the band portion with respect to the tip portion (2'), whereby before the introduction of the sock (2) in a loading duct (3) a step is provided of inversion of the sock (2) if the band portion is not oriented in the chosen direction, or a step of rejection. The sock (2) is selectively conveyed in the duct (3) by an air flow in either one or in the other direction. Also the preliminary stretching step of the sock (2) is carried out by an air flow after preliminary grasping first end thereof, whereby the second end engages the sensors. A mechanical dragging is provided (12) of the sock starting from its second end through the sensors (13), which scan at least part of the first end.
摘要:
A device for dispensing at least one thread at a feed or drop of a circular machine for knitting hosiery or the like, particularly for single-cylinder circular machines. The device comprises at least one thread guide (2,3) which is arranged at a feed or drop of a circular machine (4) for knitting hosiery or the like and has an end (2a,3a) for dispensing a thread which laterally faces the needle cylinder (5) proximate to its upper end, in the needle work area of the machine (4). The thread guide (2,3) can controllably move with respect to the needle cylinder (5) for shifting its thread dispensing end (2a,3a) along a path which has a component substantially parallel to the tangent, located in a plane which is substantially perpendicular to the axis (5a) of the needle cylinder (5), to the needle cylinder (5) in a region at which it is arranged.
摘要:
Apparatus for the automatic orientation of tubular articles, such as stockings and the like, in which one end is thicker than the other, comprising a tubular chamber (1) with an inlet section (I) and an outlet section (U) for, respectively, the admission and exit of the articles (2), characterized in that said chamber (1) is provided with two cascade filter-valves (3, 30) each of which, when in operating condition, prevents the passage of the thicker end (21) and allows the passage of the thinner end (20) of the articles to be treated, said chamber (1) exhibiting a branch (10) whose mouth is in correspondence of the space between said filter-valves (3, 30) and being associated, in conjunction with its branch (10), to an aspirator (9) by means of which an air flow is generated able to convey the in-process articles as desired.
摘要:
Apparatus for the formation of gussets to be applied in the crotch region of pantyhose articles upon the assembly thereof on a machine having a plurality of shapes (2) over which the stockings to be assembled to form pantyhose articles are fitted in pairs, the gussets being formed out of a ribbon (30), coming from a relevant input section (I), by means of a cutter (4) located downstream of said section (I), characterized in that it comprises a first plane (7) upstream of the cutting unit (4), a second and a third planes (8,9) each of which is apt to engage a corresponding side of the ribbon (30), said second plane (8) being movable from and to the ribbon (30)-inputting section (I) and said third plane (9), located downstreaam of the cutting unit (4), being movable between a position in which it results in face-to-face relationship with the second plane (8) and a position in which it engages the individual gussets (66) already formed, in an arrangement suitable for the transfer thereof to the crotch region of the pantyhose article (Fig. 1).
摘要:
A slider for double-cylinder circular knitting machines which comprises an elongated laminar body (12) which has a first longitudinal side (13) which is meant to be rested on the bottom (80a) of an axial slot (80) formed in the curved surface of the lower needle cylinder (81) or in the curved surface of the upper needle cylinder (81) and at least two heels (15,16) which protrude transversely to the longitudinal extension of the laminar body (12) on the second longitudinal side (14) of the laminar body (12) that lies opposite the first side. The laminar body (12) has, proximate to one of its longitudinal ends, a hook (17) for engagement with a needle (8). A first one (15) of the two heels (15,16) is arranged on a portion of the laminar body (12) which can move with respect to the remaining part of the laminar body (12) in a direction which has a component which is transverse with respect to the longitudinal extension of the laminar body (12) for the transfer of the first heel (15) from an inactive position to an active position, or viceversa. The first heel (15) is spaced from the first side (13) of the laminar body (12) more in the active position than in the inactive position.
