CA 2197450

A web coating apparatus (20) includes a supply roll (26) of web (22) and a wind-up spindle (86) for receiving a discrete length of the web (22). Fluid is discharged from a coating die (92) in a direction toward the wind-up spindle (86) to coat the web (22) as the web (22) is wound about the wind-up spindle (86). A variable speed pump (108) directs fluid through the coating die (92) at flow rate that is proportional to the speed of advancement of the web (22). The apparatus (20) is particularly useful for coating discrete lengths of orthopedic splinting and casting tape that is packaged for single patient use.

Un appareil (20) de revêtement pour bande comprend un cylindre d'alimentation (26) de bande (22) et un axe (86) d'enroulement servant à recevoir une longueur discrète de la bande (22). Du fluide sort d'une matrice (92) de revêtement dans un sens allant vers l'axe (86) d'enroulement pour recouvrir la bande (22) lorsque cette dernière (22) s'enroule autour de l'axe (86) d'enroulement. Une pompe (108) à vitesse variable dirige le fluide dans la matrice (92) suivant un débit proportionnel à la vitesse de marche de la bande (22). Cet appareil (20) est particulièrement utile pour recouvrir des longueurs discrètes de bandes de contention et de bandes plâtrées utilisées en orthopédie conditionnées pour un usage unique par le patient.
