摘要:
A device for winding and unwinding a wire, such as a relatively thin electric cable is described. It comprises a winding element (1) suitably in the form of a drum and a wire guidance means (4) which is rotatable relative to the winding element (1) and axially movable in relation to same. The device is characterized particularly in that the circumference of the winding element (1), speed of rotation and axial speed are so adjusted mutually and to the diameter of the wire that the wire on winding is wound up on the winding element (1) by means of the wire guidance means (4), rotation by rotation repetitively, from the surface of the winding element (1) up to a maximum radial extension.

The present invention relates to a chain winder which has a casing, a chain housed at least partially within the casing and extension means operable to cause the chain to extend out from the casing and also to retract back into the casing. The chain winder also includes a clutch mechanism which is operable to allow the chain to be extended out from the casing, or retracted back into the casing, without operating the extension means.

An extendible, coilable member (2) is reversibly configurable between a coiled form and an extended form (2a). At least one surface of the member (2), typically an inner surface, is provided with resilient protrusions (2b). Upon extension of the member (2) to the extended form, the protrusions (2b) adopt a first state in which they protrude from the surface of the member (2). Upon rolling of the member (2) to the coiled form, the protrusions (2b) flex so as to lie between the turns of the coiled member (2).

A reel assembly (10) having a spool (20) comprising a drum core (22) and side disc flanges (24) attached to the drum core (22) for retaining a wound hose (26) on the spool (20), and a release mechanism (120) operatively engaging the spool (20) via a drive shaft (110). The release mechanism (120) has a pair of rotatable hubs (132, 134) arranged in axial alignment and having a clamping spring (136) fitted around the rotatable hubs (132, 134) and arranged to clamp the hubs (132, 134) together in fixed rotational relation, wherein the clamping spring (136) opens to releases the rotatable hubs (132, 134) when the spool (20) is rotated in a payout direction so that the rotatable hubs (132, 134) disengage and the spool (20) can freewheel.

A device (1) for feeding self-adhesive or "pressure sensitive" labels to a labelling machine comprises a frame (2) and supporting means (3) comprising a supporting plate (17) for supporting a reel (4) of web (5) with labels applied to it, and also comprises at least one guide element (28, 29) designed to be at least partly inserted in a central hole (7) of the reel (4) which can rotate about it. The device (1) also comprises a detaching station (8) for detaching the labels from the web (5), feeding means (9) for feeding the web (5) to the detaching station (8) and recovery means (10) for recovering the web (5) without labels. The supporting plate (17) is removably associated with the frame (2) and the supporting means (3) also comprise a containment head (30) switchable between an open configuration, in which it allows the coupling with and uncoupling from the frame (2) of the supporting plate (17), with the reel (4) placed on it, and an operating configuration, in which it allows the reel (4) to be held between itself and the supporting plate (17), allowing reel (4) rotation.

Trata-se de sistema de instalação (10) de pares de cabos solares (c1)/(c2) em cada respectivo módulo fotovoltaico ou painel solar (PS) que, em conjunto a outros idênticos, compõe uma usina fotovoltaica (UF) ou similar capaz de produzir energia elétrica a partir de energia solar; dito sistema de instalação (10) de pares de cabos solares (c1)/(c2) é compreendido por conjunto de manobras fabris e operacionais 'in loco', ou seja, no terreno de instalação dos módulos (MF), conjunto de manobras que é realizada em duas etapas básicas, quais sejam: - etapa (E1) - operacional fabril idealizada para o planejamento dimensional (PD) dos 'lances longos' e 'curtos' dos cabos (c1)/(c2), bem como, a montagem dos cabos (c1)/(c2) preparados com conectores (20) em embalagens individuais (30) como carretéis, rolos ou bobinas, por sua vez, dispostos em carrinhos condutores que podem ser tracionados de forma mecânica (40A) (por veículo motor) ou de forma manual (40B) (por operário); ditos cabos 'preto' (c1) e 'vermelho' (c2) para a instalação simultânea de fase e neutro são instaladas numa mesma embalagem (30); - etapa (E2) – operacional de instalação 'in loco' dos cabos solares (c1)/(c2) em suportes (50) previamente instalados nos perfis estruturais (61) de 'trackers' (60) da linha de painéis solares (PS); nesta etapa os cabos solares (c1)/(c2) são fornecidos em embalagens individuais (30) acomodadas em membros de apoio (41) previstos em qualquer dos carrinhos condutores (40A) ou (40B).
摘要:
A dispensing system for dispensing cutting wire to be used in a glazing panel cut out procedure has a mounting device with a docking station for docking a wire store device. The wire store device mounts on the docking station in order to dispense the wire. The mounting device can have a rotary means operable to pay out cutting wire from the system. The rotary means is controllable to adjust the applied torque required to operate the rotary means.
